ASTM D5537-03<\/h3>\n

Historical Standard: Standard Test Method for Heat Release, Flame Spread, Smoke Obscuration, and Mass Loss Testing of Insulating Materials Contained in Electrical or Optical Fiber Cables When Burning in a Vertical Cable Tray Configuration<\/h4>\n
\n

ASTM D5537<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This is a fire-test-response standard.<\/p>\n

1.2 This test method provides a means to measure the heat released and smoke obscuration by burning the electrical insulating materials contained in electrical or optical fiber cables when the cable specimens, excluding accessories, are subjected to a specified flaming ignition source and burn freely under well ventilated conditions. Flame propagation cable damage, by char length, and mass loss are also measured.<\/p>\n

1.3 This test method provides two different protocols for exposing the materials, when made into cable specimens, to an ignition source (approximately 20 kW), for a 20 min test duration. Use it to determine the heat release, smoke release, flame propagation and mass loss characteristics of the materials contained in single and multiconductor electrical or optical fiber cables.<\/p>\n

1.4 This test method does not provide information on the fire performance of materials insulating electrical or optical fiber cables in fire conditions other than the ones specifically used in this test method nor does it measure the contribution of the materials in those cables to a developing fire condition.<\/p>\n

1.5 Data describing the burning behavior from ignition to the end of the test are obtained.<\/p>\n

1.6 This test equipment is suitable for measuring the concentrations of certain toxic gas species in the combustion gases (see Appendix X4).<\/p>\n

1.7 The values stated in SI units are the standard (see IEEE\/ASTM SI 10); the values stated in parentheses are for information only.<\/p>\n

1.8 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.<\/p>\n

1.9 Fire testing of products and materials is inherently hazardous. Employ adequate safeguards for personnel and property in conducting these tests.<\/p>\n

1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n
