CEN/TC 321/WG 2 - High Explosives

This European Standard specifies a method to calculate the detonation characteristics at the constant-volume explosion state and some parameters derived thereof.

This European Standard specifies the requirements for high explosives for civil uses when subjected to test methods defined in the standards referred herein.

This document specifies a series of boosters for testing purposes.

This document specifies a method for determining the sensitiveness to friction of explosives. This method is not applicable to liquid products.

This document specifies a method for determination of the quantity of nitrogen oxides and carbon oxides produced by the detonation of explosives for use in underground works.

This European Standard specifies a method for the verification of the initiation of a high explosive by a specified initiation system.
This method is applicable to high explosives in cartridge or bulk form, both unconfined and confined.

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.

This European Standard specifies a method for the determination of the ability of cartridged explosives to transmit detonation.

This European Standard specifies a method for determining the velocity of detonation of an explosive. The method is applicable to explosives for civil uses in cartridged or bulk form.

This European Standard specifies methods for determining the density of high explosives for civil uses, in cartridged or bulk form.

This European Standard specifies a method for determining the sensitiveness to impact of explosives.

This European Standard specifies a method to assess the stability of explosives by subjecting them to elevated thermal conditions.

This European Standard specifies a method for determining the ability of high explosives for civil uses to detonate while under applied hydrostatic pressure.
This method is applicable to high explosives in cartridges and as bulk products intended for use under conditions where hydrostatic pressure may adversely affect their safety and reliability. The method is limited to explosives that are able to detonate without confinement at normal atmospheric pressure.

This European Standard specifies a method of determining the resistance to water of cartridged or bulk high explosives for civil uses, which are designed to be used for blasting operations in wet conditions.
