コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the scientific research, production, testing, and acceptance of commercial detonators. It covers various types including industrial electric detonators, industrial electronic detonators, and nonel detonators. It is not applicable to detonators used in oil and gas wells or other special applications.

技術要求

This standard specifies comprehensive safety and technical requirements for commercial detonators. It mandates that all products must have traceable identity information and specific material restrictions; for instance, aluminum and its alloys must not be used in certain components for coal mine permissible detonators. Manufacturers must ensure strict adherence to these material and identification guidelines. The standard outlines rigorous performance criteria including anti-vibration, tensile strength, and anti-impact properties to ensure detonators do not explode or suffer structural damage under mechanical stress. It also introduces specific electrical safety parameters such as maximum non-firing current and electrostatic sensitivity. Products must demonstrate reliable safety under various environmental and mechanical stresses. For industrial electronic detonators, the standard defines advanced electrical immunity requirements, including resistance to DC voltage impulses, AC voltage shocks, and radio frequency (RF) sensitivity. Additionally, coal mine permissible detonators must meet strict combustible gas safety degree requirements to prevent igniting methane environments. Compliance with these electrical and environmental thresholds is mandatory for market access.

試験方法

The standard details various testing procedures to verify compliance. Key tests include the anti-vibration test (using a specific cam-type vibration machine) and the tensile strength test (applying a static tensile force), which are elaborated in the normative appendices. These tests are designed to simulate harsh transportation and usage conditions. Other evaluations involve electrostatic sensitivity testing per WJ/T9042, RF sensitivity testing per GB/T27602, and combustible gas safety testing per GB18096 for coal mine applications. Manufacturers must follow these exact methodologies during batch and type inspections.

よくある質問

What products are regulated under GB 19417-2025?

This standard regulates commercial detonators used in general industrial blasting, specifically categorizing them into industrial electric detonators, industrial electronic detonators, and nonel detonators. It does not apply to detonators specifically designed for oil and gas wells or other special applications.

Are there any major updates from the previous GB 19417-2003 version?

The 2025 version is a comprehensive revision of GB 19417-2003. It introduces new requirements for electronic detonators, including voltage impulse and RF sensitivity tests, and adds strict safety criteria for anti-impact, anti-drop, and temperature resistance. It also mandates traceable identity information and specific material restrictions for coal mine applications.

How does GB 19417-2025 differ from international ISO standards?

While the standard references general concepts found in international frameworks, it heavily relies on Chinese national (GB) and industry (WJ/T, GA) standards for specific testing methodologies. Manufacturers must strictly follow these localized testing protocols to achieve compliance in the Chinese market.

The summary above provides a high-level overview of GB 19417-2025. To ensure complete compliance for your products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
