This fire-test-response standard covers a small-scale laboratory
procedure for determining comparative burning characteristics of
solid-plastic material, using a 20-mm (50W) premixed flame applied
to the base of specimens held in a vertical position.
NOTE 1—This test method and the 20 mm (50W) Vertical Burning
Test (V-0, V-1, or V-2) of ANSI/UL 94 are equivalent.
NOTE 2—This test method and Test Method B of IEC 60695–11–10 are
equivalent. IEC 60695–11–10 has replaced ISO 1210.
NOTE 3—For additional information on materials that burn up to
the holding clamp by this test method, see Test Method D635. For
test methods of flexible plastics in the form of thin sheets and
film, see Test Method D4804. For additional information on
comparative burning characteristics and resistance to burn-through,
see Test Method D5048.
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 the appendix is intended
for quality assurance and the preselection of component materials
It is possible that this test is applicable to nonmetallic
materials other than plastics. Such application is outside the
scope of this technical committee.
This test method does not cover plastics when used for building
construction, finishing or contents such as wall and floor
coverings, furnishings, decorative objects etc. In addition, the
fire resistance (in terms of an hourly rating), flame spread, smoke
characterization and heat release rate are not evaluated by this
test. Other fire tests exist and shall be used to evaluate the
flammability of materials in these intended end use product
The values stated in SI units are to be regarded as standard. No
other units of measurement are included in this standard.
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 hazard or fire risk assessment of the
materials, products, or assemblies under actual fire
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.
