Description / Abstract:

This fire-test-response test method covers a small-scale laboratory procedure for determining the relative burning characteristics and the resistance to burn-through of plastics using small bar and plaque specimens exposed to a 125-mm (500-W nominal) flame.

NOTE 1—This test method is equivalent to IEC 60695-11-20.

NOTE 2—For additional information on comparative burning characteristics of solid plastics in a vertical position, see Test Method D3801.

This test method was developed for polymeric materials used for parts in devices and appliances. The results are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application. The final acceptance of the material is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment.

The classification system described in Appendix X1 is intended for quality assurance and the preselection of component materials for products.

If found to be appropriate, it is suitable to apply the requirements to other nonmetallic materials. Such application is outside the scope of this technical committee.

This test method is not intended to cover plastics when used as materials for building construction or finishing

Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

This standard is used to measure and describe 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 hazards or fire risk assessment of materials, products, or assemblies under actual fire conditions.

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. See 6.1.1 for a specific hazard statement.
