GB Standards

Understand the standard family before applying the document

China uses multiple national-standard designations. In the national standards system, GB identifies mandatory national standards and GB/T identifies recommended national standards. Project applicability can also involve regulations, industry standards, local requirements, owner specifications, adopted international standards, and contractual obligations.

HazBasis uses the standards resource page to help global teams understand where a Chinese standard fits in the engineering workflow and how it relates to NFPA, ASTM, IEC / EN / ISO, API, VDI, or company requirements used elsewhere in the project.

Core GB / GB/T standards relevant to HazBasis process-safety work

This is a representative engineering map, not a complete register of Chinese standards. Standard status and project applicability should be verified against the official National Standards Full-text Disclosure System and the governing project requirements.

Combustible Dust & Dust Explosion Testing

GB 15577-2018 — Dust Explosion Prevention and Protection

A core Chinese national safety standard for facilities where combustible dust explosion hazards may exist.

GB/T 16425-2018 — Minimum Explosive Concentration (MEC)

Supports determination of the minimum concentration of a dust cloud capable of propagating an explosion under the specified test method.

GB/T 16426-1996 — Maximum Explosion Pressure and Maximum Rate of Pressure Rise

Provides test-method direction for dust explosion severity parameters used in hazard assessment and protection engineering.

GB/T 16429-2026 — Minimum Ignition Temperature of Dust Cloud

Supports evaluation of dust-cloud ignition by hot environments / surfaces under the specified test method.

GB/T 16430-2018 — Minimum Ignition Temperature of Dust Layer

Supports evaluation of hot-surface ignition hazards for deposited dust layers.

GB/T 16427-2018 — Dust Layer Resistivity

Relevant to electrostatic behavior and ignition-risk evaluation for powder / dust systems.

Electrostatic Hazards

GB 12158-2024 — General Requirements for Preventing Electrostatic Accidents

This current national standard provides a Chinese framework for prevention of electrostatic accidents. A sound assessment still requires process-specific evaluation of charge generation, accumulation, conductivity / resistivity, grounding and bonding, isolated conductors, insulating surfaces, personnel, FIBCs, transfer operations, and ignition sensitivity.

Explosive Atmospheres & Hazardous Area Classification

GB 3836.14-2014 — Explosive Gas Atmosphere Area Classification

Relevant to classification of areas where explosive gas atmospheres may occur.

GB/T 3836.35-2021 — Explosive Dust Atmosphere Area Classification

Relevant to classification of areas where combustible dust clouds or layers can create explosive-atmosphere hazards.

GB/T 3836.28-2021 and GB/T 3836.29-2021

Relevant to non-electrical equipment for explosive atmospheres and control of potential ignition sources.

GB/T 25285.1-2021 — Explosion Prevention and Protection: Basic Concepts and Methodology

Provides broader prevention / protection principles that can support ignition-source and explosion-risk discussions.

Chemical Reaction Safety & Hazardous-Chemical Operations

GB/T 42300-2022 — Fine Chemical Reaction Safety Risk Assessment

This standard is directly relevant to reaction safety evaluation in fine-chemical manufacturing and creates a strong search-to-service bridge for DSC, ARC, reaction calorimetry, adiabatic testing, VSP / DIERS, scale-up, runaway-reaction assessment, and emergency relief design.

GB 30871-2022 — Special Work in Hazardous Chemicals Enterprises

Relevant to safety management for special work in hazardous-chemical enterprises. It is useful context for operational process-safety programs, although it should not be presented as a substitute for the complete regulatory / permitting framework applicable to a facility.

Bridging China GB standards with U.S. and international standards

Multinational projects often use equipment, testing programs, corporate engineering practices, and risk criteria developed under different standards systems. The objective should not be a superficial one-to-one crosswalk. The objective is to identify whether the underlying hazard question, test method, classification logic, and protection philosophy are equivalent enough for the project decision being made.

How HazBasis can support China / APAC projects

• Document assumptions, test data, engineering interpretation, and recommended safeguards for multinational project teams.
• Identify the relevant GB / GB/T standard family and the engineering question each document addresses.
• Compare Chinese requirements with NFPA, ASTM, IEC / EN / ISO, API, VDI, UN/DOT, and owner standards where cross-border alignment is needed.
• Develop test plans for combustible dust, electrostatics, flammable gases / vapors, thermal stability, and reaction hazards.
• Perform DHA, PHA / HAZOP / LOPA / QRA, hazardous-area classification, ignition-source analysis, and reaction-hazard analysis.
