1.1 This test method covers primarily the determination of ignition loss of glass fiber textiles. This method applies to glass fiber strands, twisted or untwisted, coated or uncoated; and fabrics, woven, nonwoven, knitted, coated, and uncoated, and chopped strand. This procedure may be applied to other glass textiles where the amount of organic content obtained by ignition loss is required.
Note 1: This test method may be used with other glass fiber classifications, such as C or D, but a different ignition temperature and exposure time may be required. In these cases the manufacturer should be consulted for the appropriate ignition conditions.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
