3.1 after flame time length of time for which a material continues to flame, under the specified test conditions, after the ignition source has been removed 3.2 afterglow time time for which a material continues to afterglow, under specified test conditions after cessation of after flaming or after removal of the ignition source 3.3 back of the glove back of hand, excluding fingers 3.4 cuff part of the glove that extends beyond the opening of glove body to cover the wrist area and sometimes part of the forearm 3.5 debris material separating from the specimen during the test procedure and falling from the specimen without flaming 3.6 dripping detachment of molten droplets during the melting process 3.7 flaming debris material separating from the specimen during the test procedure and igniting the filter paper 3.8 hands protective equipment against thermal risks equipment which protect hand and/or areas of the hand intended to be exposed to thermal risks Note 1 to entry: See examples in Annex A. 3.9 high thermal resistant gloves gloves which claimed at least level 3 for one of the following properties: convective heat, contact heat, radiant heat, small metal splashes, large quantities of molten metal 3.10 hole opening, break, or discontinuity of any size in the original structure of the test specimen’s material caused by application of the test flame 3.11 melting liquefaction of the material under the influence of heat 3.12 innermost layer layer closest to the wearer’s skin 3.13 reinforcement additional layer which does not cover the full area where the protection is claimed Note 1 to entry: Most of the time, this area has a limited surface to preserve comfort and dexterity of the gloves.
4 General requirements 4.1 General Where protection against other than thermal risk is needed the specific standard shall be used. The protective gloves according to this document shall meet all the applicable requirements of ISO 21420:2020. When parts of the glove are made from dissimilar materials, these dissimilar materials shall be tested separately, except if another way is specified in the standard. The results of each material shall comply with the requirements given in 4.5. In those circumstances when the sample size is significantly larger than the particular part of the glove or hands protective equipment against thermal risks being tested, then the manufacturer shall be requested to supply samples of identical material. 4.2 Cleaning All tests required in this document shall be performed on unused gloves or hand protective equipment unless otherwise specified.
