Alcance y aplicabilidad

This standard specifies the safety and protection technical requirements for color printer and processer systems. It is applicable to silver halide imaging color printing equipment, while digital and other color photo output devices may refer to it for execution. This standard is mandatory for all manufacturers of applicable color printing equipment entering the Chinese market.

Requisitos técnicos

The standard outlines comprehensive safety guidelines focusing on the design and structural integrity of color printing equipment. It mandates that devices must prevent personal injury from electric shock and other hazards under normal, abnormal, or single-fault conditions. Key areas include requirements for enclosures (fire and mechanical), safety interlocks, and protection against dangerous moving parts. Electrical safety is a core focus, specifying requirements for touch current, dielectric strength, and grounding performance. The equipment must withstand specific AC and DC voltage tests without breakdown, and grounding connections must meet strict resistance limits to prevent corrosion and ensure safety. Additionally, the standard addresses chemical usage, requiring that hazardous chemicals be avoided or prevented from direct human contact, with appropriate warning labels if unavoidable. It also sets limits on radiation and electromagnetic interference, specifically referencing IEC 60073 for control devices and GB 7247.1 for laser products. Thermal and fire protection requirements dictate that accessible parts must not reach temperatures capable of causing burns, and components must be designed to minimize ignition risks. Manufacturers must ensure materials used do not cause allergic or toxic reactions and meet appropriate insulation and combustion ratings.

Métodos de ensayo

Testing procedures involve evaluating components according to GB 4943 for safety compliance. Key tests include dielectric strength testing by applying 1500V AC or 2121V DC for one minute to check for breakdown, and grounding resistance measurement by calculating resistance from voltage drop and current. The standard also requires verification of safety interlock systems for fail-safe operation and mechanical strength testing to ensure structural durability against foreseeable operational stresses.

Preguntas frecuentes
