Overview

EN 13630-8:2025 - published by CEN - specifies a laboratory test method for verification of resistance to water of detonating cords and safety fuses used in civil explosives. The standard defines immersion arrangements, sample preparation, test conditions and the criteria for a pass/fail result. It replaces EN 13630-8:2002 and is intended to verify whether these initiation products maintain performance after water exposure.

Key topics and technical requirements

• Scope: Verification of water resistance for detonating cords and safety fuses (freshwater from the tap).
• Test samples:
  • Detonating cord: 5 samples, (2 000 ± 50) mm each; seal both ends.
  • Safety fuse: 5 samples, (1 500 ± 50) mm each; seal both ends.
• Immersion conditions:
  • Temperature: (23 ± 10) °C (water and ambient).
  • Duration: 24 h immersion for each sample.
  • Immersion depth: test pieces positioned so at least 1 000 mm is below the water surface; bottom part at 500 mm depth.
• Apparatus (examples):
  • Water tank, pulleys (min. Ø100 mm) and a tensile weight arrangement for detonating cords.
  • Weight of (500 ± 50) g for safety fuses to hold midpoint against tank bottom.
  • Means of sealing (non-reactive), length gauge, thermometer, hygrometer.
  • Witness plate (EN AW‑6082 aluminium) and detonators for verifying detonation on cords.
• Post-immersion verification:
  • Detonating cords: test initiation reliability per EN 13630-7:2025.
  • Safety fuses: measure burning duration (unconfined) per EN 13630-12:2025 and calculate time per 1 m.
• Pass/fail criteria: All five samples must pass the respective follow-up tests to be recorded as “pass”; otherwise, “fail”.
• Test report must cite EN 13630-8:2025 and include identification of the explosive, environmental conditions, water temperature, tensile load (for cords), witness method, burning durations (for fuses) and observations.

Practical applications

• Verifying field robustness of detonating cords and safety fuses after water exposure.
• Quality control and product development for manufacturers of initiation systems.
• Pre-qualification testing for suppliers used in mining, quarrying, civil demolition and controlled blasting where wet conditions may occur.
• Regulatory compliance documentation and conformity assessment related to Directive 2014/28/EU (informative Annex ZA).

Who should use this standard

• Explosive manufacturers and R&D labs
• Accredited testing laboratories and quality assurance teams
• Procurement and specification engineers in mining, construction and demolition
• Regulatory bodies and conformity assessors
