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 design, manufacturing, testing, inspection, use, and maintenance of various hand-held electrostatic spray guns—including both liquid and powder coating variants—and their auxiliary devices. It covers essential equipment such as gun controllers, high-voltage generators, and high/low voltage cables. Manufacturers and engineers involved in industrial coating equipment must comply with these mandatory safety requirements.

技術要求

The standard outlines comprehensive mechanical structure and electrical safety requirements. Mechanically, it mandates robust housing strength to withstand impacts and drops, along with strict IP54 ingress protection per GB/T 4208. Equipment must feature a conductive handle surface of at least 20 cm² with a grounding resistance not exceeding 1 MΩ to prevent static accumulation. Electrically, the standard specifies that high-voltage cables must have reliably grounded shielding, and non-current-carrying metal parts must be securely connected to the ground terminal. The high-voltage generator must be controlled by the spray gun's switch, which must default to the 'off' position without any locking mechanism for the 'on' state. Furthermore, the equipment must pass high-voltage insulation and short-circuit tests without experiencing breakdowns or component damage. A critical safety parameter is the ignition energy limit: liquid electrostatic spray guns must not exceed a safe ignition energy of 0.24 mJ, while powder spray guns are limited to 2 mJ. All pressurized components must also withstand specific hydrostatic and pneumatic pressure thresholds without leakage.

試験方法

GB 14773-2025 mandates a series of rigorous evaluations, including impact and drop tests to verify mechanical durability, and a cable pull test applying a 150 N tensile force. Environmental and electrical integrity are verified through an IP54 protection test, a high-voltage insulation test, and a short-circuit test. Crucially, an ignition test using specific gas mixtures (propane for liquid guns, methane for powder guns) is required to ensure the safe ignition energy limits are met under maximum output voltage.

よくある質問

What products are regulated under GB 14773-2025?

The standard regulates hand-held electrostatic spray guns (both liquid and powder) and their auxiliary devices, including gun controllers and high/low voltage cables.

Are there any major updates from the previous GB 14773-2007 version?

The 2025 version removes the maximum temperature rise marking requirement, updates definitions for controllers and cables, and modifies the drop height and impact test parameters. It also introduces stricter requirements for testing environments and high-voltage insulation procedures.

How does GB 14773-2025 differ from ISO or IEC standards?

It aligns with international safety principles but is a mandatory Chinese national standard. It specifically references GB/T 4208 for IP54 ratings and GB/T 3836.1 for explosive environment equipment, requiring localized compliance verification for the Chinese market.
