8.18 Thread Heat Resistance Test.

8.18.1 Application.

This test method shall apply to each type of sewing thread used in the construction of flame-resistant lifesafety harnesses and belts.

8.18.2 Samples.

Samples for conditioning shall be lengths of thread 150 mm (6 in.) or greater.

8.18.3 Specimens.

8.18.3.1

A total of three different specimens of each thread type shall be tested.

8.18.3.2

All specimens shall be conditioned as specified in 8.1.2 prior to testing.

8.18.4 Apparatus.

8.18.4.1

An electrically heated stage having a circular depression large enough to insert a micro-cover glassshall be used. The stage shall have a variable transformer controlling the rate of heat input into thestage.

8.18.4.2

The following equipment shall also be used:

Armored stem thermometer with a range of 150°C to 300°C accurate to 1°C

Low-powered magnifying glass

Two micro-cover glasses

Spatula, pick needle, or other instrument for applying pressure to the micro-cover glasses

Soxhlet extraction apparatus

8.18.4.3

The following reagents shall be used:

Chloroform, USP

U.S. Pharmacopoeia reference standards for melting point or other pure materials for calibratingthe apparatus

8.18.5 Procedure.

8.18.5.1

The specimen shall be extracted with chloroform for a minimum of 20 extractions in a Soxhlet extractorand dried. The specimen shall then be cut into lengths of 2 mm ( 1 ⁄16 in.) or less.

8.18.5.2

The apparatus shall be calibrated by determining the melting point of a pure material of known meltingpoint. The melting point of the pure material shall be in the range of the melting point of the fiber beingtested. The value obtained shall agree within +1°C of the known value.


85 of 96 4/5/2016 1:11 PM

8.18.5.3

If the approximate melting point of the specimen is not known before testing, it shall be determined by atrial run.

8.18.5.4

In subsequent determinations immediately following the trial run or initial determination, the stage ineach case shall be cooled to approximately 50°C below the expected melting point before the specimenis placed for testing.

8.18.5.5

The specimen shall be placed in a small mound on a cover glass and covered with another cover glass.The two cover glasses shall be pressed together gently but firmly, and placed in the circular depressionon the stage. The temperature of the stage shall be raised with some rapidity to within 15°C of theexpected melting point, and thereafter at a rate of 3°C to 4°C per minute. At this rate of temperaturerise, a slight pressure shall be applied on the upper glass cover by pressing with a spatula, pick needle,or other instrument so that the complete fiber is in contact with the cover glass.

8.18.5.6

The specimen shall be observed with the aid of a magnifying glass, and the melting point taken as thetemperature at which flow of the specimen is observed. At the observed melting point, the temperatureshall be read to the nearest °C (°F).

8.18.6 Report.

8.18.6.1

The melting point of the sample unit shall be the average of the results obtained from the specimenstested and shall be recorded and reported to the nearest °C (°F).

8.18.6.2

The pass/fail results for each specimen tested shall be recorded and reported.

8.18.7 Interpretation.

One or more thread specimens failing this test shall constitute failing performance for the thread type.

Second Revision No. 81-NFPA 1983-2016 [ Section No. A.5.1.1.8 ]

A.5.1.1.8

When life safety rope is purchased, the AHJ should ensure that the product label(s) with the informationas specified in 5.15.1.1 and 5.1.2 is attached and remains with the rope until placed in service. Whenthe product label is removed from the rope, the label should be retained in the AHJ’s permanent roperecords.

It is very important that the information on the product label(s) and the information required in 5.15.1.2 tobe supplied by the manufacturer reach the persons who will actually be using the rope. It is useless for thesupply personnel or equipment officer to remove the product label and other pertinent information andsimply retain them in the rope record file. The persons who potentially will be using the rope need to beprovided with all the information available. Copies of the product label(s) and other pertinent informationshould be maintained with the rope wherever the rope is in service awaiting use so that the potential userscan consult the information.

Where life safety or escape line is purchased in long lengths and then cut by the end user agency to makeseveral life safety ropes or escape lines, the product label(s) should be photocopied or otherwisereproduced and attached to each life safety rope when it is sent into service. The end user(s) (in a firedepartment it probably would be a fire company) should keep the copy of the product label(s) and anyother pertinent information for reference and have the product label and other information readily availableso that they can be reviewed by all potential users whenever necessary.

Ropes can be damaged in use by high stresses, impact loading situations, abrasion, kinking, heat, andexposure to chemicals and other products.

Ropes should be inspected by a qualified person before and after every operation and carefully storedbetween each use. Records should provide a history of each rope and should call for regular inspectionand replacement as necessary. Any rope that fails to pass inspection or has been impact-loaded shouldbe destroyed immediately.

It is recommended that departments establish an inspection program and shelf-life criteria for their ropesbased on the conditions and environments encountered in their respective operations.

The destruction of rope means that it should be removed from service and altered in such a manner that itcould not mistakenly be used as a life safety rope. This could include disposal or removal of the label andcutting the rope into short lengths to be used for utility purposes.

A.5.2.1.1

When escape line is purchased, the purchaser or the AHJ should ensure that a product label with theinformation as specified in 5.25.2.1 and 5.2.2 is attached and remains with the rope until placed inservice. This label should be retained either in the AHJ’s rope records or with the user of the rope forreference.

Escape line is intended only for emergency self-rescue situations and cannot be used for other roperescue situations. Escape rope is designed for one emergency use only and should be destroyed afteruse. This does not include use for training where ropes are not subjected to excessive conditions such asstress, impact-loading situations, abrasion, kinking, heat, and exposure to chemicals and other products.

Escape line is intended to be carried by a fire fighter or other emergency services personnel so that it willbe available in unanticipated situations from which self-rescue using the rope is the only option. Therefore,the escape line should be carefully stored and periodically inspected by a qualified person to ensurestatus and condition of the rope. During inspection, if there is any doubt as to the suitability of the escapeline for use, it should be destroyed immediately and replaced.

A.8.7.4.1

In most cases, the portable anchor device will be weakest at its greatest (or highest) extension. However,many devices have multiple ways they can be used. Different rigging configurations could be stronger orweaker than others. It is intended that the testing be done in the configuration specified in themanufacturer's instructions to the user that would yield the lowest strength results. For example, anchorslings multiple configuration straps can be rigged in a basket, end-to-end, or choker configuration. Eachconfiguration will likely yield different results. The minimum breaking strength reported is for the weakestconfiguration allowed by the manufacturer’s instructions.
