Overview

SIST EN 13763-6:2025 is a European standard developed by CEN addressing the verification of resistance to cracking of leading wires used in electric and electronic detonators for explosives in civil applications. The standard specifies a precise test method to assess the durability of plastic insulation on leading wires under low-temperature conditions, aimed at preventing insulation failure that can compromise electrical performance and safety.

This 2025 revision supersedes the previous EN 13763-6:2003 standard, introducing significant updates in test procedures, apparatus requirements, and reporting protocols. It applies exclusively to electric and electronic detonator leading wires, excluding non-electric detonators, detonating cord relays, surface connectors, shock tubes, and electronic initiation systems.

Key Topics

• Test Scope: Focus on electric detonators’ leading wire insulation, especially its resistance to cracking at low temperatures reflecting conditions in practical civil explosive uses.

• Test Principle: The method involves making loops in wire samples, conditioning them at minimum operation temperatures, then subjecting them to a sudden pulling force by dropping a weight to reveal potential insulation cracks.

• Apparatus Requirements:

  • Conditioning chamber maintaining temperature tolerance ±2 °C
  • Rigid frame for securing wire samples
  • Specified weights (500 ± 10 g)
  • Release system (e.g., electro-magnetic) to drop the weight consistently

• Sample Preparation:

  • 25 test specimens, each about 500 mm long
  • Loops made with specific diameter requirements to simulate stress points
  • Testing includes twin and single insulated wire configurations

• Testing Procedure:

  1. Attach wire with loops to a frame and weight
  2. Condition at low temperature for at least 1 hour
  3. Release the weight causing stress to the insulated wire
  4. Visually inspect for any cracks exposing the electrical conductor
  5. Repeat the process for all samples until failure is detected or completed

• Results Evaluation: The test passes only if none of the 25 samples shows cracks exposing the wire; otherwise, it fails.

• Reporting: Mandatory inclusion of test conditions, specimen ID, temperature, and outcome ("pass" or "fail") with descriptive observations if a failure occurs.

Applications

SIST EN 13763-6:2025 is essential for manufacturers, quality control laboratories, and regulatory bodies involved in the production, certification, and supervision of explosives with electric or electronic initiation systems. Its implementation ensures:

• Reliable detonator performance in cold environments by confirming insulation durability.
• Enhanced safety by reducing risk of accidental failure due to insulation cracking.
• Support for manufacturers in meeting EU regulatory requirements, especially Directive 2014/28/EU on explosives for civil uses.
• Standardized testing that facilitates market acceptance and regulatory compliance across Europe and EFTA countries.

This testing standard is critical for industries such as mining, demolition, construction, and quarrying, where the use of civil explosives demands rigorous quality assurance under varying environmental conditions.

Related Standards

• EN 13763-1:2025: Specifies general requirements for detonators and relays, including vocabulary and apparatus details referenced in SIST EN 13763-6:2025.
• EN 13857-1:2025: Provides terminology for explosives for civil uses, which supports consistent definitions in EN 13763-6.
• EN ISO/IEC 17025:2017: General requirements for testing laboratory competence, informing test report and laboratory practices though not mandated for test conformity in EN 13763-6.
• Directive 2014/28/EU: European legislation governing market availability and safety supervision of civil explosives, with SIST EN 13763-6:2025 recognized as a harmonized standard providing presumption of conformity.

By adhering to SIST EN 13763-6:2025, stakeholders ensure that electric detonator leading wires maintain integrity under low-temperature stress, aligning product quality with stringent safety and regulatory frameworks critical for explosives used in civil sectors worldwide.
