This document specifies a method to determine the tendency of a propellant to undergo transition from deflagration to detonation (DDT). It applies to propellants of a grain size up to 8 mm. This method does not apply to black powder and rocket propellant.
NOTE 1   Due to the nature of the shape of grains (heterogeneous), the combustion of the rocket propellant can cause a crack of the grain causing an explosion of the rocket motor.
NOTE 2   Black powders properties differ significantly from propellant and explosives because black powders are capable of maintaining stable combustion at high velocities without experiencing deflagration - detonation transition.

This document specifies a test method for the verification of the insensitiveness to friction of explosives for blasting and explosive substances.
This document is also applicable to black powder used for blasting.
This document is not applicable to boosters.
This document is not applicable to compact solid explosives.
This document is not applicable to liquid explosives.
This document also applies to solid gun propellants, solid rocket propellants, black powder used as propellants, for safety fuse or for pyrotechnics and powder cakes as covered by FprEN 13938-1:2025.

This document specifies a method for the determination of burning rate under ambient conditions for solid gun propellants. It is applicable to solid gun propellants and black powder in their original form up to a grain size of 8 mm.
NOTE 1   Knowledge of burning rate is of high importance to manage risks associated with handling such explosives and of high importance to assess whether performance characteristics are met.
NOTE 2   In cases where propellants having grain size higher than 8 mm are generally used, their burning rate is more influenced and controlled by parameters of element containing thereof, and thus knowledge of their burning rate at ambient condition is not of high importance.

This document specifies a test method for the verification of the thermal stability at 75 °C of explosives for blasting, boosters and explosive substances.
This document also applies to black powder when used for blasting.
This document also applies to solid gun propellants, solid rocket propellants, black powder used as propellants, for safety fuse or for pyrotechnics and powder cakes as covered by FprEN 13938-1:2025.

This document specifies a test method for the verification of the resistance to water of explosives for blasting and boosters.
NOTE   This test method applies to situations where an explosive for blasting or a booster is subjected to high humidity and contact with water.
This document does not apply to black powder.
This document does not apply to explosive substances.

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 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 document specifies a test method for the verification of the resistance to hydrostatic pressure of explosives for blasting and a test method for the verification of the resistance to hydrostatic pressure of explosives for boosters.
This document does not apply to black powder.
This document does not apply to explosive substances.

This document specifies a method for checking small rocket motors for voids and fissures and provides a list of non-destructive testing (NDT) methods for detecting voids and fissures in other solid rocket propellants.

This document specifies a method for the determination of resistance to electrostatic energy for propellants containing a mass fraction of at least 5 % of particles which pass through a 1 mm sieve. This method does not apply to black powder.
NOTE   If the mass fraction of particles smaller than 1 mm size is less than 5 % the propellant is considered to be insensitive to electrostatic energy and this test is not performed.

This document gives guidance on the issues related to the conformity assessment of explosives manufactured on-site.
On one hand, it specifies requirements to be considered for the assessment during the design phase of the explosive and a simple and robust approach to follow for the assessment of the conformity in the production phase.
And on the other hand, it specifies requirements for the mobile manufacturing units and their accessories as a contribution to the guarantee of the conformity of explosives produced in on-site conditions with no access to a laboratory.
This document gives guidance on also basic requirements for explosives loading equipment.
This document does not apply to the preparation of multi-component explosives as they neither require manufacturing equipment nor mechanical loading.
NOTE 1   This document does not address the requirements of the transport of dangerous goods regulations.
NOTE 2   This document does not address the requirements established in Directive 2006/42/EC (Machinery).
NOTE 3   Despite the provisions given in this document, other provisions provided for in state, federal or local regulations apply.
NOTE 4   The intention of this document is not to hinder the development and use of new technologies (including equipment and processes) for the on-site manufacture of explosive, but because of limited access to testing resources on site, the approach consisting of having specified requirements for the equipment is valid to ensure the conformity of future products and technologies.
