Standard Test Method for Rigidity of Polyolefin Film and Sheeting
 N D2923

Annotation

This test method describes two procedures for measuring the rigidity of polyolefin film and sheeting.

Procedure A prescribes a procedure using high-voltage static eliminators and the use of TFE-fluorocarbon2-coated plates to overcome the spurious effects of static electricity and friction.

Procedure B prescribes the use of a fine powder on uncoated plates to achieve a similar effect.

NOTE 1—Although the two procedures are designed to achieve similar effect, they may not achieve the same results.

The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use.

NOTE 2—There is no known ISO equivalent to this standard.
