Scope

1.1 This practice provides for the separation and identification of monomeric plasticizers in poly (vinyl chloride) (PVC) compounds by gas chromatography (GC).

1.2 The values in SI units are to be regarded as standard.

1.3 The text of this practice references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in Tables and Figures) shall not be considered as requirements of this standard.

1.4 Test Method D 2124 is an alternative infrared procedure.

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.

There is no ISO equivalent for this standard.

Significance and Use

Separation and identification of plasticizer components in PVC is necessary to correlate performance properties with polymer composition. This test method provides a means of determining monomeric plasticizers including adipates, azelates, benzoates, citrates, phthalates, sebacates, and trimellitates.

Other methods successfully used to analyze plasticizers are column chromatography, HPLC, GPC, FTIR, and GC/MS.

This method is not applicable to plasticizers with molecular weights over 700 g/mol including epoxidized soybean oil and polymeric plasticizers.
