Organization: ASTM
Publication Date: 1 July 1977
Status: inactive
Page Count: 4
scope:

This method covers a small-scale laboratory screening procedure for comparing the relative rate of burning of plastics in the form of flexible, thin sheets or films, tested in the vertical position. This method should be used to establish relative burning characteristics of plastic materials and should not be used as a fire hazard test method.

Caution-During the course of combustion, gases or vapors, or both, are evolved which may be hazardous to personnel. Adequate precautions should be taken to protect the operator.

NOTE 1-Method D 635, Test for Rate of Burning and/or Extent and Time of Burning of Self-Supporting Plastics in a Horizontal Position2, Method D 1433, Test for Rate of Burning and/or Extent and Time of Burning of Flexible Thin Plastic Sheeting Supported on a 45-deg Incline2, and Method D 2863, for Measuring the Minimum Oxygen Concentration to Support Candle-like Combustion of Plastics (Oxygen Index)2, may provide additional related information on the burning characteristics of plastics in sheet form.

This standard should be used to measure and describe the properties of materials, products, or systems in response to heat and flame under controlled laboratory conditions and should not be used for the description or appraisal of the fire hazard of materials, products, or systems under actual fire conditions.3

NOTE 2-The values stated in SI units are to be regarded as the standard.

2 Annual Book of ASTM Standards, Part 35.

3 This caveat has been placed in the standard in accordance with a policy established by the ASTM Board of Directors in September 1973. This caveat will remain in this standard until Committe E-39 on Fire Hazard Standards has approved it as a fire standard.
