ASTM WK28497

    New Practice for Preparing Consumer Electronic Devices (CEDs) Containing Liquid Crystal Displays (LCDs) For Waste-Leaching Tests

    (What is a Work Item?)

    Developed by Subcommittee: D34.01.02 | Committee D34 | Contact Staff Manager


    1. Scope

    1.1 This practice describes a procedure to disassemble, segregate, cut and mill, and sample consumer electronic devices (CEDs) containing liquid crystal displays (LCDs) for the determination leachable metals and other substances. Applicable waste-leaching methods include the Federal toxicity characteristic leaching procedure (TCLP). 1.2 This practice is applicable to both laptop computers and other devices with LCD monitors. 1.3 This practice is not applicable for preparing CED components for mercury testing. 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 and health practices and determine the applicability of regulatory limitations prior to use.


    waste leaching; e-waste sampling


    This standard is needed to provide a recommended practice for preparing consumer electronic devices containing liquid crystal displays for determining total and extractable concentrations of leachable metals and other substances that may pose a potential risk to human health and the environment when disposed as waste.

    The title and scope are in draft form and are under development within this ASTM Committee.
