(Test Method)Standard Test Method for Carbon Black Content in Olefin Plastics
Standard Test Method for Carbon Black Content in Olefin Plastics
SIGNIFICANCE AND USE
The information provided by this test method is useful for control purposes and is required by various material specifications and for the calculation of optical absorptivity.
SCOPE
1.1 This test method covers the determination of the carbon black content in polyethylene, polypropylene, and polybutylene plastics. Its use with acrylic or other polar monomer modifications which might affect the accuracy is not recommended. Determinations of carbon black content are made gravimetrically after pyrolysis of the sample under nitrogen. This test method is not applicable to compositions that contain nonvolatile pigments or fillers other than carbon black.
1.1.1 This test method is not applicable to materials containing brominated flame retardant additives at the end.
1.2 The values stated in SI units are to be regarded as standard. The values in brackets are given 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.
This test method is similar to ISO 6964-1986(E) in title only. The technical content is significantly different.
