ASTM Dll

The trapezoid test method (ASTM Dll 17) is recommended for determining the tear resistance of nonwoven fabrics. An outline of a trapezoid is marked on a 7.5 x 15 — cm specimen, and the nonparallel sides are clamped in the jaws of the tensile-testing machine. The load is applied to the specimen in such a way that the tear propagates across the specimen width. The value of the breaking load is obtained from the load—elongation curve and is determined primarily by the bonding or interlocking of the fibers of the composite structure.

In ASTM, fire standards are developed primarily by committee ES (Fire Standards), but are also developed by other committees. The most important materials committees developing fire standards are D20 (Plastics), D9 (Electrical Insulation), Dll (Rubber), D13 (Textiles) and others have also developed fire standards, particularly F7 (Aircraft), F15 (Consumer Products), F23 (Protective Clothing), F25 (Ships) and F33 (Correctional Facilities), which tend to be related to the interests of specific members. 

Mortality testing is carried out where textile samples are enclosed with a number of larvae for fourteen days. Weighings before and after exposure are taken and visual damage is recorded 46), Results can be reported according to standard test method Insects, Resistance of Textiles to AATCC Test Method 24-1994 (47), or similar test methods such as ASTM D 582, Dll 16-65, IWTO-9-62, and IWTO-14-64, and ISO 3998.
