Applicable in China, specifying fire resistance performance and safety compliance requirements for fire doors. Products must meet GB 12955 testing standards and obtain the mandatory 3C Certification for market approval.

What is GB 12955 & 3C Certification?

GB 12955 is China's national standard for fire-resistant doors (current version: GB 12955-2008), specifying core technical requirements such as material selection, fire resistance performance, and smoke tightness. It serves as the "technical guideline" for fire-resistant door production and quality evaluation.

3C Certification (China Compulsory Certification) is a mandatory conformity assessment system. For fire-resistant doors, 3C Certification takes GB 12955 as the core technical basis. Only products meeting GB 12955 can pass 3C Certification, which is a mandatory "market access certificate" for fire-resistant doors in China.

Together, GB 12955 (technical standard) and 3C Certification (mandatory assessment) form the authoritative certification system for domestic fire-resistant doors, ensuring product safety and compliance.

Why GB 12955 & 3C Certification Matter in Fire Safety？

1.Technical Foundation for Fire Protection

GB 12955 sets clear fire resistance standards (e.g., Class A ≥1.5h, Class B ≥1.0h, Class C ≥0.5h) to ensure fire-resistant doors can block fire and smoke effectively. 3C Certification verifies compliance with this standard, eliminating substandard products.

2.Dual Guarantee for Quality and Reliability

GB 12955 unifies technical benchmarks, avoiding inconsistent quality. 3C Certification requires rigorous testing by designated institutions and confirms enterprises’ stable production capacity, ensuring both product performance and manufacturing reliability.

3.Core Prerequisite for Safety Compliance

In building fire safety, GB 12955 is the technical basis for design and acceptance, while 3C Certification is a legal requirement for procurement. Without meeting GB 12955 or holding 3C Certification, fire-resistant doors cannot be used in construction projects.
