Geltungsbereich und Anwendbarkeit

This standard applies to rapid prototyping machines that utilize laser as processing energy for additive manufacturing processes. It specifically targets equipment where lasers provide sufficient energy to melt, sinter, vaporize, or phase-change forming materials. This standard is mandatory for all manufacturers of laser-based rapid prototyping machines in China.

Technische Anforderungen

The standard mandates comprehensive safety measures to prevent mechanical hazards such as sharp edges, tipping, and sliding. Manufacturers must implement reliable interlocking guards and dual mechanical/electrical limit switches for moving parts. It references GB/T 15706.1-2007 for basic machinery safety concepts and requires that detachable guards weigh no more than 6kg with an opening force not exceeding 40N. Control circuits must comply with GB 5226.1 to ensure reliable operation and prevent hazards from control information interruption. Emergency stop functions must immediately isolate the laser beam, shut down the machine, and release all stored energy. Electrical equipment inside the forming chamber requires heat resistance, corrosion resistance, and explosion-proof ratings. High-voltage lasers must include mechanisms to rapidly release capacitor energy. The standard specifies strict laser radiation protection according to GB 7247.1, requiring beam isolation and fail-safe beam blocks to prevent exposure above Class 1 AEL. Manufacturers must provide adequate ventilation and exhaust systems to manage harmful substances and prevent fire risks. Additionally, the standard sets limits on noise levels and requires appropriate lighting and clear warning labels.

Prüfverfahren

The standard outlines verification procedures including visual inspections, manual checks, and specific tests. Key testing methods involve evaluating the reliability of interlocking protective devices through repeated trials, conducting electrical safety tests (protective grounding continuity, insulation resistance, and dielectric strength per GB 5226.1), and performing temperature control tests for laser heating systems. Hazardous substance emissions are tested according to GB/T 18569.1 and GB/T 18569.2.

Häufige Fragen

What products are regulated under GB 25493-2010?

It regulates rapid prototyping machines that use laser as processing energy for additive manufacturing, specifically those that melt, sinter, or vaporize forming materials.

Are the safety requirements in GB 25493-2010 mandatory?

Yes, Chapters 5 to 7 of the standard are mandatory, covering safety protection requirements, usage information, and inspection methods, while the remaining sections are recommended.

What is the maximum allowable noise level for these machines?

The overall noise sound pressure level of the machine must not exceed 75dB(A), and the machine should not produce screaming or impact sounds during operation.
