Historical (view previous versions of standard)
Significance and Use
This test method is capable of yielding duplicate test data, in 20 min or less, for a simple carbon black content determination.
This test method is suitable for manufacturing quality control, technical service, and research work.
For referee requirements, the number of replicate measurements is increased. Alternatively, a control sample of known carbon black content is tested with the unknown sample.
Test Method D 1603
1.1 This test method covers the determination of black polyethylene compounds containing channel or furnace black. It is not applicable to thermal black.
1.2 This test method is not suitable for plastics that char on pyrolysis and should not be attempted for plastics that generate corrosive fumes on pyrolysis.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 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.
