【国外标准】 Standard Test Method for Determination of the Blooming of Brominated Flame Retardants onto the Surface of Plastic Materials by Ion Chromatography

5.1 This test method will allow the quantitative determination of the bromine originating from the flame retardant that has bloomed onto the surface after aging under specified conditions. Based on the known structure of the flame retardant used, the amount of the flame retardant that bloomed can also be calculated.5.2 Section 14 contains some safety recommendations.1.1 This test method covers the quantification of the blooming of brominated flame retardants onto the surface of plastic materials by an ion chromatographic method.1.2 The test method involves recovery of the deposits on the surface of plastic materials, containing brominated flame retardants, on unaged specimens, on specimens aged at 70°C for 14 days and on specimens aged at 70°C for 35 days. These deposits are quantitatively analyzed to obtain the fraction of brominated flame retardant that has bloomed onto the surface.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: There is no known ISO equivalent to this standard.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
