Where a waste contains substance assigned H260 or H261, i.e. a substance which is capable of releasing a highly flammable gas at a rate in excess of 1 litre of gas per kilogram of substance per hour when water is added, it is possible to calculate the minimum concentration of the substance in the waste that would make it hazardous by HP 3 (fifth indent). Below this concentration the waste is not considered hazardous pursuant to HP 3 (fifth indent). At or above the concentration the waste is considered to be HP 3, or tested. Examples of substances and calculation are provided by the UK Guidance and are presented in the following section.
