This could causematerial

27、 from the primary charge to become loose creating a risk of inadvertent initiation because of friction or otherstimuli on the loose explosive.1 ScopeThis European Standard specifies a method for assessing the ability of the explosive content of plain detonators towithstand the vibration likely to be

28、 experienced in normal use and handling.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated referenc

29、es, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

39、 to EN 60068-2-6 with the following procedure:With the 25 detonators in position in the pockets of the detonator holder, secure the latter firmly in place in thecentre of the vibrating table.Set the maximum vibration amplitude (zero to peak) to 0,25 mm.Start the vibrator.Stop the vibrator after 60 m
