1.2 This test method provides three testing procedures. Procedure A involves top surface ignition, Procedure B involves propagating ignition, and Procedure C is a short procedure involving the comparison with a specified minimum value of the oxygen index.
1.3 Test specimens used for this test method are prepared into one of six types of specimens (see Table 1).
| Test Specimen TypeA | Dimensions | Material Form | |||
| Length, | Width, | Thickness, mm | |||
|
| I | 80 to 150 | 10 ± 0.5 | 4 ± 0.25 | for molding materials |
|
| II | 80 to 150 | 10 ± 0.5 | 10 ± 0.5 | for cellular materials |
|
| IIIB | 80 to 150 | 10 ± 0.5 | ≤ 10.5 | for sheet materials |
|
| IVC | 70 to 150 | 6.5 ± 0.5 | 3 ± 0.25 | alternative size for |
|
| VB | 140 ± 5 | 52 ± 0.5 | ≤10.5 | for flexible film or sheet |
|
| VIBD | 140 to 200 | 20 | 0.02 to 0.10 | for thin film; limited to film |
1.4 This test method provides for testing materials that are structurally self-supporting in the form of vertical bars or sheet up to 10.5-mm thick. Such materials are solid, laminated or cellular materials characterized by an apparent density greater than 15 kg/m³.
1.5 This test method also provides for testing flexible sheet or film materials, while supported vertically.
1.6 This test method is also suitable, in some cases, for cellular materials having an apparent density of less than 15 kg/m³.
1.7 This test method 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.
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.9 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. Specific hazards statement are given in Section 10.
1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
