コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to all industrial centrifuges (including industrial dehydrators) equipped with metal drums. It comprehensively covers the safety requirements for the design, manufacturing, installation, and operation of these machines across various industries such as food, pharmaceuticals, chemicals, and metallurgy. It is mandatory for all industrial centrifuge manufacturers targeting the Chinese market. The standard does not apply to laboratory or non-industrial centrifuges.

技術要求

GB 19815-2021 establishes a comprehensive hazard identification and risk reduction framework based on the principles of GB/T 15706. It mandates that centrifuges must adopt intrinsic safety design measures to eliminate or minimize risks at the source. Manufacturers must ensure that residual risks are adequately addressed through safety guards and clear usage information. The standard details specific mechanical safety requirements for both design and manufacturing. This includes strict strength calculations for the rotating drum, reliable anti-loosening measures for fasteners, and the use of appropriate materials. Welding procedures for critical components like the drum must be performed by certified personnel and undergo non-destructive testing. It also introduces specific requirements for centrifugal casting drums. Regarding electrical system safety, the standard requires automatic monitoring and alarm functions for critical parameters like vibration, temperature, and pressure. Equipment intended for use in explosive or flammable environments must possess valid explosion-proof certifications and comply with relevant hazardous area classifications. Emergency stop circuits must be capable of halting all dangerous operations. Furthermore, the standard sets material and operational safety requirements to handle toxic, corrosive, or volatile substances. Centrifuges processing flammable materials must feature reliable inert gas protection systems with automatic shutdown capabilities upon protection failure. Comprehensive product and technical archives must be maintained by the manufacturer throughout the machine's design lifespan.

試験方法

Compliance is evaluated through a combination of document review, visual inspection, and physical testing. Key evaluation areas include drum strength verification via calculation reports, non-destructive testing of welds, and dynamic balancing checks. Physical measurements for noise, vibration, and temperature rise must be conducted in accordance with referenced national testing standards. The standard utilizes a pass/fail matrix where all critical items must achieve 100% compliance, and at least 85% of major items must pass.

よくある質問

What products are regulated under GB 19815-2021?

The standard applies to all industrial centrifuges with metal drums, including industrial dehydrators, regardless of whether they are sedimentation, filtration, or mixed-type models. It is mandatory for all manufacturers targeting the Chinese market.

Are there any major updates from the previous version, GB 19815-2005?

The 2021 version restructures the hazard list and safety requirements, adds specific safety provisions for centrifugal casting drums, and modifies the dynamic balancing requirements for rotating parts. Manufacturers previously certified under the 2005 version must update their compliance documentation.

How does GB 19815-2021 differ from international standards like EN 12547?

While GB 19815-2021 is primarily based on Chinese industry practices and referenced GB standards, it was partially revised with reference to EN 12547:2014 (Centrifuge - Common safety requirements). Engineers familiar with EN standards will find many conceptual similarities, but specific testing thresholds and documentation requirements remain distinct to China.

The summary above provides a high-level overview of GB 19815-2021.
