Explosives for civil uses - High explosives - Part 7: Determination of safety and reliability at extreme temperatures
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.

Overview
prEN 13631-7:2021 - "Explosives for civil uses - Explosives - Part 7: Determination of safety and reliability at extreme temperatures" (CEN) defines how to verify that civil-use explosives perform safely and reliably when exposed to extreme temperatures. This draft European Standard (submitted for CEN enquiry and intended to supersede EN 13631-7:2003) applies to explosives (excluding black powder) and clarifies adaptations to existing test methods for low and high temperature conditions.
Extreme temperatures are defined as below −40 °C or above +80 °C.
Key topics and technical requirements
- Scope: Extends and modifies specific test methods to cover extreme temperatures; focuses on where reliability could be affected by temperature.
- Covered test methods (modifications specified):
- Determination of resistance to hydrostatic pressure (prEN 13631-6): procedures for temperatures up to 100 °C and above 100 °C, including water circulation, thermocouple monitoring, heating arrangements (e.g., electric heating ribbon - min. 2 000 W per 5 L steel tube), insulation and maintenance of target temperature for 1 hour.
- Verification of the means of initiation (prEN 13631-10): conditioning in a thermostatically controlled oven/refrigerator (±2 °C), thermocouple monitoring, temperature hold for ≥1 h, initiation within ±5 °C of conditioning temp, three test repetitions.
- Determination of transmission of detonation (prEN 13631-11): whole test arrangement conditioned as above and tested per the initiation procedure.
- Test controls and instrumentation: conditioning chambers, thermocouples, insulated containers and adherence to thermostat accuracy of ±2 °C.
- Test reporting requirements: conformity with EN ISO/IEC 17025:2017 plus specific data (temperature/time to reach test temp, cartridge dimensions, wrapping material, initiation means, density, maximum air gap for transmission, etc.).
- Explicit exclusions: no standardized extreme-temperature methods are provided here for friction sensitivity, impact sensitivity, resistance to water, booster initiating capability, or velocity of detonation - the manufacturer must supply suitable methods for these.
Practical applications and users
Who uses prEN 13631-7:
- Explosive manufacturers and R&D teams validating product safety at temperature extremes
- Independent test laboratories performing conformity and performance testing
- Regulatory bodies and notified authorities assessing compliance with Directive 2014/28/EU
- Safety engineers specifying explosives for harsh-environment civil applications (mining, construction, seismic operations)
Practical value:
- Ensures predictable initiation and detonation performance in cold and hot climates
- Provides harmonized procedures for conditioning, monitoring and reporting test results
- Supports conformity assessment and market surveillance in the EU
