ASTM D5477-02

Заменен
Standard Practice for Identification of Polymer Layers or Inclusions by Fourier Transform Infrared Microspectroscopy (FT-IR) (Withdrawn 2011) — 4 стр.
Причина отмены

This practice described the techniques used for detecting two different polymer entities as follows: (1) Abnormal specks or spots on a surface or in the film that are objectionable as defects and (2) Layers of different polymeric sheets commonly used as barrier films made by coextrusion.

Formerly under the jurisdiction of Committee D20 on Plastics, this practice was withdrawn in January 2011 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

A speck will ultimately cause a failure to occur by virtue of its appearance in a film or by the decrease in electrical or mechanical properties in the polymer substrate (see Specification D 1248).

Область применения

1.1 This practice describes the techniques used for detecting two different polymer entities as follows:

1.1.1 Abnormal specks or spots on a surface or in the film that are objectionable as defects and

1.1.2 Layers of different polymeric sheets commonly used as barrier films made by coextrusion.

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

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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.

Note 1—There is no similar or equivalent ISO standard.
