Test Methods

Part A of the Annex to the Test Methods Regulation provides the following test method which may be regarded in the assessment of HP 1 ‘Explosive’: — A.14. Explosive Properties Wastes containing substances listed in Table 8 should be tested for explosive properties in accordance with the ECHA CLP Guidance. Separate sections are provided in ECHA CLP Guidance for testing of mixtures containing: — organic peroxides — self-reactive substances and mixtures — explosives. The CLP Regulation classifies self-reactive substances and mixtures in one of the seven categories of ‘types A to G’, see the ECHA CLP Guidance. Waste containing an organic peroxide or a self-reacting substance, where the waste is classified by testing as Type A (H240) or Type B (H241), displays HP 1. Where this is not the case, a waste classified as Type C, D, E or F (H242) displays HP 3. A waste containing another substance listed in Table 8, where the waste is classified by testing as Unstable Explosive (H200), Division 1.1(H201), 1.2(H202), 1.3(H203) or 1.4(H204), displays HP 1. A detailed example for an assessment of organic peroxides according to HP 1 can be found in Annex 1, Section 1.4.7.
