ASTM D 2859：Test Method for Ignition Characteristics of Finished Textile Floor Covering Materials
Abstract 摘要
This test method provides a procedure for identification of those finished textile floor covering materials that can be rated as flame-resistant under specific controlled laboratory conditions.This test method does not specify the use of an underlay material. If an underlay material is used to assess the effect of a specific underlay in combination with a specific floor covering, such a variation in procedure must be noted in the report.
In this test, results are observed with the specimens in a horizontal plane. Different results are possible if the same material is tested or used in any other plane.
Test Method D 2859 for testing finished textile floor covering materials for flammability is considered satisfactory for acceptance testing of commercial shipments since the method has been used extensively in the trade for acceptance testing. In cases of disagreement arising from differences in values reported by the purchaser and the seller when using this method for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller shall be determined with each comparison being based on testing specimens randomly drawn from one sample of material of the type being evaluated.
The test procedures of this standard are part of the standards for the surface flammability of carpets and rugs of the U.S. Consumer Product Safety Commission4 . The acceptance criterion of these standards requires that at least seven out of eight individual specimens of a given carpet or rug have passed the test, that is, the charred portion of a tested specimen shall not extend to within 25.4 mm [1.0 in.] of the edge of the hole in the flattening frame at any point.
