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.
