1. Scope

1.1 This specification covers polyolefin monofilament yarn materials, and test methods for standard polyolefin monofilaments. While designed primarily for testing standard polyolefin monofilaments, many of the procedures can be used, with little or no modification, for other polyolefin monofilaments. However, testing on non-standard polyolefin monofilaments should be conducted with caution. See for a definition of standard polyolefin monofilament.

1.2 Only on condition that interlaboratory precision data are available for the specific procedure is any test method described, or referenced in this specification, recommended for acceptance testing of commercial shipments of polyolefin monofilaments.

1.3 The specification for polyolefin raw materials appears in Section 4.

1.4 The test methods for individual properties appear in the following sections:

In most instances, the suitability of these procedures for polymeric yarns in general, and polyolefin monofilaments in particular, is already accepted in commercial transactions (see ).

1.5 The values stated in SI units are to be regarded as standard; the values in English units are provided as information only and are not exact equivalents.

The following safety hazards caveat pertains only to the test methods described in this specification: This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems, 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.
