Escopo e aplicabilidade

This standard applies to the design, installation, operation, maintenance, and management of electrostatic powder coating processes and their associated equipment. It is also applicable to the acceptance of electrostatic powder coating engineering projects. It serves as a mandatory safety code for facilities utilizing powder coating technologies. Additionally, it can be referenced for fluidized bed and electrostatic fluidized bed coating methods.

Requisitos técnicos

The standard mandates comprehensive safety protocols for powder coating operations, focusing heavily on explosion prevention and worker safety. It reclassifies traditional fire hazard zones into explosion hazard zones, requiring strict adherence to dust explosion prevention principles. Facilities must ensure that the average suspended powder concentration in the spray booth remains below 50% of its lower explosive limit (LEL). For equipment design, the standard specifies that spray booths, recovery units, and purification devices must be constructed from non-combustible or flame-retardant materials. It dictates strict interlock control mechanisms; for instance, if the recovery or exhaust system fails, the powder spraying operation must automatically cease. Equipment surfaces contacting powder must not exceed the powder's softening point temperature to prevent ignition. Regarding ventilation and dust control, the standard requires that exhaust air volume be calculated based on both dust concentration control and dust escape prevention. The work environment must maintain a permissible dust concentration limit, and exhaust ducts must prevent powder accumulation beyond a specified thickness. Recycled air used in the working area must undergo continuous monitoring to ensure it meets strict safety thresholds.

Métodos de ensaio

Compliance verification involves regular monitoring of ventilation parameters, such as average face velocity at spray booth openings and exhaust air volume. Facilities must conduct periodic checks on dust concentration limits within the spray booth and exhaust ducts. The standard also requires routine inspection of electrostatic grounding resistance for all conductive components and verification of interlocking system effectiveness between spray, recovery, and exhaust systems. Regular cleaning and maintenance cycles for equipment and ducts are mandated to prevent hazardous dust accumulation.

Perguntas frequentes

What products and processes are regulated under GB 15607-2023?
