10 min NOTE 1 It can be dangerous to base considerations of safe wear time of given chemical protective clothing only on the value of normalized breakthrough time for a specific tested chemical. NOTE 2 For example, in the case that the permeation rate for a given clothing material and tested chemical remains slightly below 1,0 µg/(cm2·min) for greater than or equal to 480 min, this material can be rated class 6 for this chemical according to Table 7, but the cumulative permeated mass during the 480 min will be only slightly below 480 µg/cm2. This level of permeation can be dangerous depending of the toxicity of the chemical. NOTE 3 Chemical protective clothing materials should thus be better evaluated with respect to cumulative permeation and classified by cumulative permeation time, i.e. by the time to the amount of cumulative permeated mass, to which the skin can be exposed with regard to the skin/dermal toxicity of the tested chemical/mixture. 4.11.3 Classification of permeation resistance by cumulative permeation time When tested in accordance with ISO 6529, Method A (liquids) or Method B (gases) the average time to reach the cumulative permeated mass determined based on the skin/dermal toxicity classification of the chemical (see Annex D, Table D.1), to be tested, shall be classified according to the levels of performance given in Table 8. The resultant average value for the time to cumulative permeation, determined according to ISO 6529 and in accordance with Annex C, shall be used for the purpose of performance rating and classification.
