PREFACE

BCGA was established in l971, formed out of the British Acetylene Association, which existed since l901. BCGA members include gas producers, suppliers of gas handling equipment and users operating in the compressed gas field. The main objectives of the Association are to further technology, to enhance safe practice, and to prioritise environmental protection in the supply and use of industrial gases, and we produce a host of publications to this end. BCGA also provides advice and makes representations on behalf of its Members to regulatory bodies, including the UK Government. Policy is determined by a Council elected from Member Companies, with detailed technical studies being undertaken by a Technical Committee and its specialist Sub-Committees appointed for this purpose. BCGA makes strenuous efforts to ensure the accuracy and current relevance of its publications, which are intended for use by technically competent persons. However this does not remove the need for technical and managerial judgement in practical situations. Nor do they confer any immunity or exemption from relevant legal requirements, including by-laws. For the assistance of users, references are given, either in the text or Appendices, to publications such as British, European and International Standards and Codes of Practice, and current legislation that may be applicable but no representation or warranty can be given that these references are complete or current. BCGA publications are reviewed, and revised if necessary, at five-yearly intervals, or sooner where the need is recognised. Readers are advised to check the Association’s website to ensure that the copy in their possession is the current version.

TERMINOLOGY AND DEFINITIONS

Critical Temperature The temperature above which the substance cannot exist in a liquid state.

Gas A substance which:

(a) at 50°C has a vapour pressure greater than 3 bar absolute; or

(b) is completely gaseous at 20°C under standard pressure of 1013 mbar

* Note: 1013 mbar = 760mmHg

High-pressure Liquefied

Gas

A gas which has a critical temperature greater than -50ºC and less than or equal to 65ºC.

Low-pressure Liquefied

Gas

A gas which has a critical temperature above 65°C.

Note: Hydrogen cyanide and anhydrous hydrogen fluoride, which are liquid at 1013 mbar* pressure at 0°C but which boil at or below 30°C at that pressure shall be treated as low-pressure liquefied gases.

Compressed Gas A gas which has a critical temperature below -50°C.

Filling Ratios The ratio of the mass of gas to the mass of water at 15°C that would fill completely a pressure receptacle fitted ready for use.

Note: The water capacity stamped on the receptacle may refer to the minimum designed water capacity of the receptacle without fittings, in which case the net water capacity must be ascertained.

Although water capacity is defined as a mass it may be expressed as a volume.

Developed Pressure

Maximum permissible

pressure

The pressure developed by the contents of the receptacle at the reference temperature for developed pressure as given in table 2.

The test pressure of the receptacle or such lower maximum allowable value as is appropriate depending on the design of the receptacle.

2

Reference Temperature for

Filling Ratio

The temperature at which the liquid density is to be evaluated for calculating the filling ratio.

Reference Temperature for

Developed Pressure

Receptacle

The temperature at which the developed pressure is to be determined.

Pressure receptacle or tank.

1 SCOPE

This code of practice specifies the maximum filling ratios and developed pressures to be used when filling, selecting or designing receptacles of above 0.5 litre water capacity for carriage of liquefied or compressed gases by road/rail within the United Kingdom. Most of the data presented in this Code of Practice is derived from BS5355, which was withdrawn by BSi in 2008.

Note 1 As guidance only, for overseas markets outside the EU, corresponding filling ratio and developed pressure data for climatic areas other than the United Kingdom are given in informative Appendix B.

Note 2 The requirements of this code of practice may be considered for use with receptacles of 0.5 litre and less, but particular attention should be given to the accuracy of filling these small receptacles.

2 GENERAL

2.1 Table 1 classifies those gases conveyed in commercial quantities for which data are given in this Code of Practice. The classification of gases as toxic, flammable or corrosive may affect the design or use of receptacles.

2.2 The reference temperatures for filling ratio and for developed pressure referred to in this Code of Practice vary with the size of receptacle. The relationship between reference temperature and receptacle volume is given in Table 2.

2.3 Where filling ratios and developed pressures are not specified for gases or gas mixtures, the procedure to be followed is included as Appendix A to this code of practice.

2.4 The developed pressure figures quoted in the various tables are assumed to be for pure gases. If impurities are present the effect on the developed pressure must be taken into account, for example, by treating the impure substance as a mixture for the purposes of Appendix A.

2.5 The filling ratios and charging pressure defined are maxima, and shall not be exceeded. In filling a receptacle, allowance shall be made for the tolerances in the weighing or charging measurements; declared filling weights will be lower than the maxima. In no case shall the developed pressure at the specified reference temperature exceed the test pressure of the receptacle or the maximum permissible pressure according to the design standard of the receptacle.

2.6 Notwithstanding the use of this Code of Practice, filling restrictions imposed in 4.1.4.1 P200 (10) of ADR shall be observed in all cases.

diameter exceeds 4.5, the volume of the receptacle may be taken as that volume contained in a length 4.5 times the external diameter.

3 LIQUEFIED GASES

3.1 Low Pressure Liquefied Gases

3.1.1 Filling Ratios

The chosen filling ratio shall be such that in no circumstances shall the liquid portion of the gas occupy more than 97% of the volume of the receptacle at the filling ratio reference temperature, nor shall the receptacle be liquid full at a temperature 5°C greater than the filling ratio reference temperature. The filling ratios to be used for the commercially pure gases listed in Table 1 are given in Table 4.

7

3.1.2 Developed Pressures

The developed pressures at the reference temperatures applying in the United Kingdom are given in Table 4.

The developed pressure at 5°C greater than the reference temperature shall not be more than 20% above the maximum permissible pressure.

Vapour pressure data for commercial butane and commercial propane as defined in BS 4250 (1) are given in Table 5.

3.1.3 Mixtures of liquefied petroleum gases

For mixtures of liquefied petroleum gases Tables 6 to 13 should be used for obtaining filling ratios appropriate to the reference temperature. The density of the mixture shall be determined experimentally at a convenient temperature and for any given reference temperature the maximum permissible filling ratio is the value at the intersection of the row beginning with the value determined for the density and the column headed by the temperature at which it was determined.

3.1.4 Mixtures of liquefied petroleum gases consisting wholly of saturated

hydrocarbons

Tables 6, 8, 10 and 12 give the maximum permissible filling ratios for mixtures of liquefied petroleum gases consisting wholly of saturated hydrocarbons.

3.1.5 Mixtures of liquefied petroleum gases consisting wholly of unsaturated

hydrocarbons or containing more than 2 mol% of C2 hydrocarbons

Tables 7, 9, 11 and 13 give the maximum permissible filling ratios for mixtures of liquefied petroleum gases consisting wholly of unsaturated hydrocarbons, or containing more than 2 mol% of C2 hydrocarbons.

3.1.6 Mixtures of liquefied petroleum gases containing both saturated and

unsaturated hydrocarbons

For mixtures consisting only partly of unsaturated hydrocarbons the maximum permissible filling ratio shall be determined

a) by reading from Tables 7, 9, 11 or 13 as appropriate;

or

b) by linear interpolation between the value in Tables 6, 8, 10 or 12 as appropriate to the reference temperature for filling ratio, density determined and temperature of density determination, and the corresponding value in Tables 7, 9, 11 or 13.

For example if 'x' is the proportion by mass of unsaturated hydrocarbons in the mixture, (FR)a and (FR)b are the filling ratios given in Tables 6, 8, 10 or 12 and Tables 7, 9, 11 or 13 respectively for the given density, temperature

8

of density determination and reference temperature, and (FR)m is the filling ratio appropriate to the mixture

(FR)m = (FR)a - x [(FR)a - (FR)b]

3.1.7 Other mixtures of low pressure liquefied gases

For other mixtures of low pressure liquefied gases the method specified in Appendix A must be followed.

3.2 High pressure liquefied gases

Filling ratios and the associated developed pressures at the reference temperatures applying in the United Kingdom for different sizes of receptacles are given in Table 3. The developed pressure shall not exceed that appropriate to the design of the receptacle. The relationship between developed and test pressure is defined in the construction standards. If it is desired to use receptacles designed for developed pressures other than those given in Table 3, then the filling ratio appropriate to the developed pressure and reference temperature shall be used.

4 Large insulated receptacles

In the case of large insulated receptacles used for the conveyance of compressed or high pressure liquefied gases at sub-normal temperatures, the mass of the gas to be filled into the receptacles shall be such that the liquid portion shall occupy not more than 98% of the receptacle volume at the highest temperature likely to be reached in conveyance or at the pressure at which any safety devices fitted operate.

* Calculated

Note: Refrigerant 114 (Dichlorotetrafluoroethane). The data is that for 1,2-dichloro-1,1,2,2-tetrafluoroethane. For 2,2,dichloro-1,1,1,2-tetrafluoroethane the density is slightly greater and the vapour pressure slightly less. The filling ratios and developed pressures recommended relate to the former isomer and are applicable to both isomers or to a mixture of these.

APPENDIX A – Determination of filling ratios and developed pressures

This appendix details the basis on which the filling ratios and developed pressures are determined, and defines the way in which they should be applied in practice. Examples are given of how properties of mixtures can be calculated. For gases not listed in this standard other known data may be used. There are available various other theoretical methods which enable properties to be predicted. When properties are calculated or estimated, a sufficient margin should be allowed to cover the uncertainties in the methodology.

A.1 Low pressure liquefied gases

A.1.1 Filling ratios for single components (see 2.4)

The filling ratio is defined so as to leave a guaranteed free space of 3% at the appropriate reference temperature. It is normally calculated from the formula

(Formula 1)

Where;

ρl is the density of liquid phase of gas at the reference temperature of filling ratio

C is the confidence limit on data for liquid density %

ρw is the density of water at 15°C.

Formula 1 assumes that the whole of the contents are in the liquid phase. If the mass of gas in the vapour phase is allowed for, slightly greater ratios could apply, calculated from the formula

Where;

ρg is the density of gaseous phase of gas at the reference temperature for developed pressure.

Note: The adjustment afforded by Formula 2 is of value only when density of the gaseous phase exceeds 0.33 g/cm3.

A.1.2 Filling ratio for mixtures

Where receptacles are to be filled with a mixture of gases or of gases and liquids, for which experimental data are not available and where the liquid densities of the individual components are known, the filling ratio can be calculated as follows.

26

An adjustment shall be made to the percentages of the components in such a manner as to reduce the filling ratio. When experience is available, and figures for tolerances of filling are known, these can be used. Otherwise a value of 2% is recommended. For example, for a mixture of 30%/70% H/L where H is the heavier component, the ratio should be calculated on the basis of 28%/72% H/L.

The formula for a mixture of two components X1/Y1 of a/b is

where;

ρa, ρb are the densities of liquid phase of components a and b at the reference temperature for filling ratio

Ca, Cb are the percentage confidence limits for liquid densities of components a and b

X1, Y1 are the nominal mass fractions of components a and b

X2, Y2 are the mass fractions of components a and b after correction for tolerances.

The procedure can be extended for mixtures of three or more components.

Note: Mixtures of hydrocarbon gases are addressed in Tables 6 to 13.

A.1.3 Pressure of mixtures

For the purposes of assessing the developed pressure of a mixture of gases where this is not known experimentally an assessment may be made by assuming that the mixture follows perfect gas laws, and the pressure depends on the molar concentration of the constituents. However for an azeotrope, which develops a pressure higher than any of its individual components, the pressure of the azeotrope shall be the value which is to be used.

Note: Mixtures of hydrocarbon gases are addressed in Tables 6 to 13.

A.2 High pressure liquefied gases

A.2.1 Filling ratio for single components (see 2.4)

A.2.1.1 Two phases.

When the design of the receptacle is such that contents when carrying an HP liquefied gas are in two phases (e.g. cryogenic conditions) then the filling ratio is defined as in A.1.1, except 2% guaranteed free space is allowed.

A.2.1.2 Single phase.

Apart from cryogenic conditions, it is more usual for a high pressure liquefied gas to be in a single phase at the reference temperature. The pressure developed at a given temperature is dependent on the filling ratio, and must be determined experimentally.

The maximum filling ratio is that which produces, at the reference temperature, a developed pressure equal to the test pressure of the receptacle, or equal to such lower value as is appropriate depending on the design of the receptacle.

A.2.2 Filling ratio for mixtures

A.2.2.1 Mixtures, which may be of high pressure liquefied gases alone or with low pressure liquefied gases, should only be assessed under such conditions as enable Formula 3 to apply i.e. the filling ratios used are sufficiently low to ensure two phase conditions (note that the densities used are those of the liquids at the references temperature for developed pressure).

A.2.2.2 Higher filling ratios than those obtained under A.2.2.1 may be permissible but

should be backed by experimental evidence.

A.3 Compressed gases

A.3.1 Mixtures of compressed gases

A.3.1.1 If a mixture has one component of more than 98% by mass, then the charging pressure may be determined as if the main component were 100% of the contents.

A.3.1.2 For mixtures other than those falling under A.3.1.1 the charging pressure may be

determined as if the component with the highest ratio of developed pressure at reference temperature to charging pressure, were 100% of the contents (except that components present in concentrations less than 0.5% by mass can be aggregated with the major component).

A.3.2 Mixtures of compressed and liquefied gases

A.3.2.1 If one component is a compressed gas of concentration 98% or more of the mixture by mass, then the charging pressure may be determined as if the main component were 100% of the contents.

A.3.2.2 Where experimental evidence is not available then theoretical methods can be used, but a generous safety margin should be applied, particularly if the compressed gases could be soluble in the liquefied gas.

APPENDIX B - Reference temperatures, filling ratios and developed pressure for

countries other than the United Kingdom

B.1 This Appendix gives details of reference temperatures, filling ratios and developed pressures for liquefied gases and developed pressures for compressed gases, which may prove useful in the design filling of receptacles intended for export outside the United Kingdom and the EC. However, exporters and those intending to supply receptacles as ships equipment should be aware that statutory requirements exist which would preclude the use of some of this data.

Conveyance of gases in ships is subject to the International Maritime Dangerous

Goods Code (IMDG) (2) which became mandatory on 1 January 2004. The IMDG contains the same P200 as the ADR (3) and the UN Model Regulations, therefore shipping conditions preclude the use of filling ratios greater that those listed in the IMDG. It is possible that other ratios could be used if there is a waiver by the competent authority for example, on short sea crossings. In the UK a Marine Guidance Note issued by the Maritime and Coastguard Agency would put this into effect for voyages between the UK and e.g. Belgium, or France or the Republic of Ireland.

Carriage of gases into the EU involves either IMDG (2), or ADR (3)/RID (4) or

both, so again the filling ratios on these international journeys cannot exceed those given in the ADR/RID P200.

Those involved should therefore ascertain the statutory requirements before using

the data in Appendix B. B.2 Table 15 classifies countries according to the absolute maximum shade

temperature attained in those countries. B.3 Table 16 lists the reference temperatures for filling ratios and developed pressures

according to the climatic areas given in Table 15. B.4 Filling ratios and developed pressure data for high pressure liquefied gases at the

reference temperatures given in Table 16 are given in Table 17. B.5 Filling ratio and developed pressure data for low pressure liquefied gases at the

reference temperatures in Table 16 are given in Table 18. B.6 For mixtures of liquefied petroleum gases, Tables 19 to 28 should be used for

obtaining filling ratios appropriate to the reference temperature. The density of the mixture should be determined at a convenient temperature, and for any given reference temperature the maximum permissible filling ratio is the value at the intersection of the row beginning with the value determined for the density and the column headed by the temperature at which it was determined. Tables 19, 21, 25 and 27 give the maximum permissible filling ratios for mixtures of liquefied petroleum gases consisting wholly of saturated hydrocarbons.

29

Tables 18, 22, 24, 26 and 28 give the maximum permissible filling ratios for mixtures of liquefied petroleum gases consisting wholly of unsaturated hydrocarbons, or containing more than 2% by volume of C2 hydrocarbons.

For mixtures containing both saturated and unsaturated hydrocarbons reference

should be made to 3.1.6. B.7 Developed pressure data for permanent gases at the reference temperatures given

in Table 16 are given in Table 29.

Table 15 - Classification of countries and territories of the world other than the United Kingdom into

climatic areas in relation to observed absolute maximum shade temperatures (1 of 2)

Values asterisked are assumed, by relation to adjacent countries, in the absence of data for the country or territory in question.

Values marked by a dagger † are the recorded maximum for the country or territory but due to the relative insufficiency of observations and the proximity of high recorded maxima in bordering countries, the classification has been raised to avoid anomaly.
