Escopo e aplicabilidade
This standard specifies the testing rules for fire electronic products conducted by quality supervision and inspection institutions in China. It applies to various testing categories, including type testing, supervised testing, and arbitration testing. It is mandatory for all manufacturers seeking compliance certification for fire electronic products in the Chinese market. The standard references GB/T 10111 for random sampling methods and GB/T 14689 for technical drawing formats.
Requisitos técnicos
The standard outlines the fundamental regulations for the inspection process rather than specific product performance parameters. It defines the criteria for sampling methods, model designation, and derivative product control. For instance, derivative products of detectors or alarms must only differ from the main model in specific aspects like base shape or sensitivity levels. Manufacturers must submit comprehensive technical documents, including circuit diagrams and software flowcharts, that exactly match the submitted samples. Furthermore, the standard establishes strict protocols for design change control post-testing. Any significant modifications to critical technical indicators require a full re-testing process to maintain compliance.
Métodos de ensaio
GB 12978-2003 categorizes inspections into five types: type testing, entrusted testing, supervised testing, scientific achievement appraisal testing, and arbitration testing. For type testing, the institution conducts a full project examination based on the corresponding product standards. If a product fails an initial test, limited re-testing is permitted under strict conditions, including doubled sample sizes and time constraints. Supervised testing utilizes a pass/fail judgment method detailed in Annex A, categorizing nonconformities into Class A, Class B, and Class C based on severity, with specific acceptance and rejection numbers defined in normal and tightened inspection tables.
Perguntas frequentes
What products are regulated under GB 12978-2003?
GB 12978-2003 regulates the testing rules for fire electronic products, including detectors, alarms, control panels, and emergency lighting. It applies to all quality supervision and inspection institutions testing these products in China.
Are there specific rules for derivative products in this standard?
Yes, the standard defines strict rules for derivative products. For example, a derivative detector model can only differ from the main model in aspects like base shape, lack of address coding, or different sensitivity levels. Any differences must not negatively impact the overall product performance.
What happens if a product fails a test during type testing?
The standard allows for limited re-testing if a product fails. However, if the total number of test items is 15 or more, re-testing cannot exceed 2 times per item or 4 times cumulatively. If re-testing cannot be completed within 6 months, the product is automatically judged as non-compliant.
The summary above provides a high-level overview of GB 12978-2003. To ensure complete compliance for your fire electronic products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
