Standard Test Method for Package Yield of Plastic Film
 N D4321

Annotation

This test method covers the determination of yield (area per unit mass) of plastic film.

Also described in this test method is the means for calculating nominal yield, given values for nominal density, and nominal thickness. This is needed since, in material specifications, limits for yield are normally stated in terms of the percent deviation of actual yield from nominal yield.

The values stated in SI units are to be regarded as the standard. The values given in brackets 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 1—This standard and ISO 4591 address the same subject matter, but differ in technical content.
