Compliance overview
Scope and applicability
This standard specifies the main methods for controlling static electricity, protective measures against static hazards, and management protocols in rubber product manufacturing. It is applicable to the engineering design, static electricity safety management of rubber product factories, and the design and manufacturing of rubber machinery. It is mandatory for facilities involved in the production of various rubber goods. It references GB 12158-1990 and GB/T 15463 for general static safety guidelines and terminology.
Technical requirements
The standard outlines fundamental measures to prevent static electricity hazards, focusing on controlling the electrostatic potential of insulators in environments with flammable mixtures. Specific limits for electrostatic potential must be strictly adhered to in order to prevent explosions and electric shocks. It mandates the use of anti-static shoes, anti-static clothing, and anti-static flooring in explosion and fire hazard zones. For static grounding, the standard specifies that the total grounding resistance between static conductors and the earth must not exceed specific limits. It also recommends increasing the relative humidity of the local environment to above 50% to prevent static accumulation on hydrophilic insulating materials. The use of various static eliminators (such as self-inductive, external power, radioactive, and ionized types) is detailed for different operational contexts. The standard provides specific protective measures for major manufacturing processes, including rubber mixing, cement manufacturing, coating, calendering, cutting, and forming. For instance, in cement manufacturing using flammable solvents, gear transmission or anti-static V-belts are required, and solvent flow velocities must be restricted. Each process has tailored mandatory or recommended safety configurations.
Testing methods
The standard outlines testing procedures to analyze hazard levels, research preventive measures, and evaluate the effectiveness of static elimination. Key testing parameters include measuring the electrostatic potential of charged bodies, ambient temperature and relative humidity, operating speed, and flammable gas concentration. It also involves testing the ground resistance of conductive floors. Various instruments like electrostatic voltmeters, high resistance meters, and human body comprehensive resistance testers are referenced for these evaluations.
