Standard Test Methods for Flammability of Electrical Insulating Materials Used for Sleeving or Tubing

Importancia y uso:

5.1 Test Method A is the required flammability test for: crosslinked chlorinated polyolefin heat-shrinkable tubing for electrical insulation (Specification D2903), crosslinked poly(vinylidene fluoride) heat-shrinkable tubing for electrical insulation (Specification D3144), and crosslinked and noncrosslinked poly(vinyl chloride) heat-shrinkable tubing for electrical insulation (Specification D3150).

5.2 Test Method A is also one of the flammability tests used for nonrigid vinyl chloride polymer tubing used for electrical insulation (in Test Methods D876), flexible treated sleeving used for electrical insulation (Test Methods D350), and heat-shrinkable tubing for electrical use (Test Methods D2671).

5.3 Test Method B is another flammability test (together with Test Method A) used for flexible treated sleeving used for electrical insulation (Test Methods D350).

5.4 Test Methods C and D are other flammability tests (together with Test Method A) used for heat-shrinkable tubing for electrical use (Test Methods D2671). In both tests the electrical insulating material is fitted with a metallic core. The electrical insulating material is tested after shrinking, but using different mandrels.

5.5 In these test methods, the test specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. The results are therefore valid only for the fire-test-exposure conditions described in this procedure.
