Textiles - Determination of lead release
WARNING - Persons using this document shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.
1 Scope
This document describes the test method for determining lead release from textiles and textile product accessories after artificial saliva treatment using the inductively coupled plasma optical emission spectrometer (ICP-OES), graphite furnace atomic absorption spectrometer (GFAAS) or inductively coupled plasma mass spectrometer (ICP-MS).
This document is applicable to the detection of textiles and textile product accessories (buttons, zippers, etc.).
2 Normative references
The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 6682 Water for analytical laboratory use - Specification and test methods
GB/T 18886-2019 Textiles - Tests for colour fastness - Colour fastness to saliva
GB/T 30156 Method of corrosion and wear for the coated accessories of textile products
GB/T 30158-2013 Determination of nickel released from accessories on textile products
GB/T 40139 Measuring method for surface areas of materials - Three dimensional area measurement based on hyperspectral imaging
3 Terms and definitions
No terms and definitions are listed in this document.
4 Principle
Place the prepared specimen in artificial saliva for oscillation treatment, use the inductively coupled plasma optical emission spectrometer, graphite furnace atomic absorption spectrometer or inductively coupled plasma mass spectrometer to determine the lead concentration in artificial saliva after oscillation treatment, and calculate the lead release from the specimen per unit time based on the specimen area. The amount of lead released shall be expressed in micrograms per square centimeter hour [μg/(cm2·h)].
