ASTM E3171-21a

Redline Standard: Standard Test Method for Determination of Total Silver in Textiles by ICP-OES or ICP-MS Analysis

ASTM E3171

Scope

1.1 This test method covers the use of inductively coupled plasma–optical emission spectrometry (ICP-OES) and inductively coupled plasma–mass spectrometry (ICP-MS) analyses for determination of the mass fraction of total silver in consumer textile products made of any combination of natural or manufactured fibers. Either ICP-OES or ICP-MS analysis is recommended as a first step to test for and quantify silver in a textile and results can be used to inform subsequent, more detailed analyses as part of the tiered approach described in Guide E3025 to determine if a textile contains silver nanomaterial(s).

1.2 This test method prescribes acid digestion to prepare test sample solutions from samples of textiles utilizing an appropriate internal standard followed by external calibration and analysis with either ICP-OES or ICP-MS to quantify total silver.

1.3 This test method is believed to provide quantitative results for textiles made of fibers of rayon, cotton, polyester, and lycra that contain metallic silver (see Section 17). It is the analyst’s responsibility to establish the efficacy (ability to achieve the planned and desired analytical result) of this test method for other textile matrices and forms of silver.

1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurements are included in this standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
