prEN 13631-7

This European Standard specifies the special conditions and procedures permitting the extension to wider ranges of applicability of the following test methods: - determination of resistance to hydrostatic pressure; - verification of the means of initiation; - determination of transmission of detonation. Standardised test methods at extreme temperatures for the following purposes are not given: - determination of sensitiveness to friction; - determination of sensitiveness to impact; - determination of resistance to water; - determination of the initiating capability of boosters; - determination of velocity of detonation. NOTE In these cases, the manufacturer of the explosive should provide a suitable test method and, in cases where the results should be checked by an independent institution or authority, the manufacturer and the institution or authority should agree upon a suitable test method.
