    Significance and Use

    5.1 Identification and quantification of phthalates: DBP, BBP, DEHP, DNOP, DINP, and DIDP are required for regulated articles. Regulations include: EU—Directive 2005/84/EC, US—Consumer Product Safety Improvement Act of 2008—section 108, Japan—Health, Labor and Welfare Ministry guideline No.336 (2010). This test method provides a procedure to identify and quantify regulated phthalates in PVC.

    5.2 Other techniques successfully used to separate and identify phthalates in PVC include GC/MS, HPLC/UV, HPLC/MS, FTIR, and GC/FID (flame ionization detector).

    1. Scope

    1.1 This test method provides a procedure to identify and quantify six phthalates by thermal desorption (TD) gas chromatography (GC) mass spectrometry (MS). The phthalates are BBP, DBP, DEHP, DNOP, DINP and DIDP.

    Note 1The method can be extended to include other phthalates.

    1.2 Within the context of this method, “low level” is defined as 1000 ppm.

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

    1.4 This test method includes references, notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in the tables and figures) shall not be considered as requirements of this method.

    1.5 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 2There is no known ISO equivalent to this test method.
