Escopo e aplicabilidade

This standard applies to fuses used in fireworks and firecrackers within the Chinese market. It covers the classification, technical requirements, testing methods, and inspection rules for these ignition components. It is applicable to all manufacturers producing pyrotechnic fuses intended for use in China. The standard specifically categorizes fuses into slow-burning, paper, and fast-burning types, making it essential for engineers designing consumer or display fireworks.

Requisitos técnicos

This standard specifies the physical and chemical requirements for firework fuses, including strict criteria for appearance, burning speed, and moisture content. Manufacturers must ensure fuses are free from defects like mildew, empty powder sections, and leakage. The standard defines specific tolerance deviations for burning speeds across different fuse categories, such as timing fuses and fast-burning fuses. Additionally, it outlines requirements for mechanical strength and environmental resistance. Fuses must withstand specific load-bearing tests without breaking, and certain types must pass moisture resistance and water resistance tests to ensure reliable ignition. Thermal stability is also mandated to prevent self-ignition under specified elevated temperatures. Dimensional tolerances for length and lateral dimensions are strictly regulated based on the fuse type.

Métodos de ensaio

The standard mandates several evaluation procedures, including visual inspection, dimensional measurement using calipers, and burning speed determination using precision stopwatches. Environmental testing is critical, involving moisture resistance, water resistance, and thermal stability tests. Chemical properties are evaluated through moisture content and hygroscopic rate determination (referencing QB/T 1941.5). Mechanical integrity is verified via load-bearing tests, and specific burning characteristics like side-ignition time are measured.

Perguntas frequentes

What products are regulated under GB 19595-2004?

This standard regulates fuses used in fireworks and firecrackers, including slow-burning fuses (such as timing fuses and safety fuses), paper fuses, and fast-burning fuses (such as kraft paper and waterproof fast fuses).

Is GB 19595-2004 a mandatory standard?

Yes, all technical requirements in this standard are mandatory for applicable products. It also includes a normative appendix (Appendix A) detailing the classification of product defects.

Are there any related standards referenced in GB 19595-2004?

The standard references several related Chinese standards, including GB 10631 for fireworks safety and quality, GB/T 10632 for sampling inspection rules, and QB/T 1941.5 for pyrotechnic powder hygroscopicity determination. Manufacturers should ensure compliance with these referenced standards as well.
