Report11. API CRA Testing Program, Paul Javora, Baker Hughes, Chair

Implement and monitor the API CRA Testing Program.

Funding Year 3 completed and the final results were reviewed and sent to the Participants.

Funding Year 4 was initiated in 2010, tests were discussed and planned, and the first four tests were implemented. Results expected in February.

The first in a series of meetings to critically review Year 1 and 2 results was held December 2010.

Hydrometers & Density measurements

Bernard Fraboulet, TOTAL Technology Specialists

TG # 6

Density & specific gravity measurements Hydrometers

Density hydrometerConcept : mass per unit of volume (ρ) SI Graduations in g/ml - kg/m3 USC Graduations in ppg Reference temperatures SI 20°C USC : 70°C ( 21.1°C)

Relative density (specific gravity) hydrometerConcept : ratio of ρ sample by ρ water at the same temperatureGraduation dimensionless Reference temperature 15.56°C /60°FRatio of sample density to water density at 60°F :

999,012 kg/m3 ≡ 0, 999 012 g/ml (8,337 ppg)

TG # 6

Hydrometer and normative references

ISO 387: 1977 Principles of construction and adjustment

ISO 649:1981 Density hydrometer for general purposes

part 1 : SpecificationsPart 2 : Test methods and use

for both part : no adoption by USA

ISO 650 :1977 Relative density 60/60°F hydrometers for general purposes

Not adoption by France and Germany and then by CEN

TG # 6

Reference & Reporting temperatureISO 387 Reference temperature

• Clause 4.1 - density hydrometer : − 20 °C (68°F) − In special circumstances : substitution to 15°C (59°F) or 27°C

(80.6°F)− 27°C i.e 80°F recommended − other reference temperatures ? USA : 70 °F ?

• Clause 4.2 : relative density hydrometer − 60°F ( 15,56°C) for liquid and water

Density reporting temperature For any measurement done at a temperature which is not the reference one, a

correction is required. General reporting : when density hydrometer is used why to report at a

different temperature than the reference ’s one ? Does it need to get a direct conversion between SI ref. temperature to

USC’s (20°C – 68°F) or between USC ref. temperature to SI’s (70°F – 21°C) ?

• Reporting temperature proposal : SI report : 20°C USC report : 70°F Left to users

TG # 6

Clause 6.2.1 Hydrometer description

More accurate description • As per ISO’s : class M100 hydrometer• 6.2.1.1 Density hydrometer• 6.2.2.1 Relative density hydrometer

Calibration :• at least quarterly

TG # 6

Temperature Correction factor

Density hydrometer • Only a correction linked to hydrometer volumetric

change is required : − Standard glass thermal volume expansion 20 x 10-6 − Table linked to readings and temperature − Minor difference lower than uncertainty if the same

table is used for 20°C or 70°F as reference temperature

− Two tables ( SI and USC) possible

TG # 6

Temperature Correction factor

Relative density hydrometer• Reference temperature 60°F • Correction whatever the reporting temperature • Correction linked to

− Glass volumetric change − Water temperature density variation

Correction factor : − Complex equation − tables of coefficient − variations as per author/references

TG # 6

Proposed changesClause 6.4.1 Temperature correction for hydrometer

6.4.1.1 Density hydrometerCorrection factor (unit kg/m3 or 10-3 g/ml)

6.4.1.2 Relative density hydrometer sub clause 6.4.1 no changes Add SI equations
