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 the safety of commercial electric water boilers and liquid heaters used for boiling or heating beverage liquids, not intended solely for household use. It covers single-phase appliances with a rated voltage not exceeding 250V and other appliances up to 480V, commonly used in restaurants, food shops, hospitals, and bakeries. It does not apply to industrial-design appliances, electrode-heated appliances, or equipment used in explosive environments.

技術要求

This standard specifies the essential safety requirements for commercial liquid heating appliances, focusing on protection against electric shock, thermal hazards, and mechanical dangers. It mandates that appliances must be Class I for electric shock protection and have a minimum IPX3 rating for water ingress. Manufacturers must ensure strict adherence to these classification requirements. The standard outlines specific structural requirements, including the mandatory installation of pressure relief devices for appliances operating above atmospheric pressure to prevent overpressure. It also specifies requirements for internal wiring, such as the durability of thermostat capillary tubes, and mandates that power cords must be oil-resistant. Appliances must be designed to prevent liquid overflow from affecting electrical insulation. Additionally, it details requirements for markings and instructions, such as specifying rated pressure, indicating liquid levels, and providing detailed installation precautions. For abnormal operation, the standard requires that thermal cut-outs protecting heating elements must be of the non-auto-reset type. Engineers must verify that all safety warnings and electrical ratings are clearly marked on the appliance.

試験方法

The standard references various testing procedures to verify compliance, including normal operation tests where appliances are run at specific voltages and water pressures to establish stable states. It includes specific splash water tests (using a designated apparatus) for IPX3/IPX4 rated appliances to ensure electrical insulation is not compromised by water exposure. Appliances must also undergo hydrostatic pressure tests on their pressurized components to verify structural integrity. Other tests involve abnormal operation conditions, such as running the appliance without water or with controllers disabled, to ensure safety mechanisms function correctly.

よくある質問

What products are regulated under GB 4706.36-2014?

The standard applies to commercial electric water boilers and liquid heaters used to boil or heat beverages, typically found in restaurants, food shops, hospitals, and bakeries. It covers appliances with a rated voltage not exceeding 250V for single-phase and 480V for others. It does not apply to industrial-purpose appliances, electrode-heated appliances, or equipment used in corrosive/explosive environments.

Are there any significant updates from the previous GB 4706.36-1997 version?

The 2014 version introduces several key updates, including new definitions for ordinary, boiling, and stepping type water boilers. It also mandates a minimum IPX3 ingress protection rating, modifies leakage current limits, and adds specific structural requirements for pressure relief and capillary tube durability. Manufacturers previously compliant with the 1997 version must update their designs to meet these new safety criteria.

How does GB 4706.36-2014 relate to international IEC standards?

GB 4706.36-2014 is based on the framework of IEC 60335-2-63:1990 but has been redrafted to suit Chinese national conditions. It must be used in conjunction with GB 4706.1-2005 (the general safety requirements). Engineers should review both standards simultaneously to ensure full compliance, as this particular standard only specifies deviations and additional requirements.

The summary above provides a high-level overview of GB 4706.36-2014. To ensure complete compliance for your products entering the Chinese market, a precise and professional translation of the full technical specifications is essential.
