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, installation, commissioning, inspection, operation, and maintenance of spray booths using flammable or combustible liquid coatings in coating operations. It covers various types of equipment including dry-type spray booths, wet-type spray booths, and electrostatic spray booths. It is mandatory for all manufacturers and operators utilizing these facilities within China. The standard specifically excludes structural requirements for building fire protection, which are covered by other regulations.

技術要求

The standard specifies comprehensive safety requirements for the overall structure, equipment, and facilities of spray booths. It mandates that spray booths must be equipped with safety ventilation devices and paint mist catchers. The structural materials must be non-combustible or flame-retardant, and the equipment must maintain negative pressure during operation to prevent gas leakage. Facilities must also comply with strict occupational exposure limits for toxic substances in the workplace air. For ventilation systems, the standard defines specific control airflow speeds based on the booth type (large, small, or spot repair) and operational mode (manual or automatic). It explicitly requires that the ventilation system must interlock with automatic spraying equipment; if ventilation fails, spraying must automatically stop. Additionally, combustible gas detectors must be installed with alarm thresholds set at no more than 25% of the lower explosive limit (LEL). Regarding electrical safety, the standard details the classification of explosive gas environment hazard zones (Zone 0, 1, and 2) based on the booth's configuration and opening types. Equipment in these zones must meet strict explosion-proof requirements. Furthermore, anti-static systems are mandatory; all conductive parts must be reliably grounded, and electrostatic spray booths must feature static elimination devices at entrances. Portable lighting is strictly prohibited inside the spray area during active spraying operations.

試験方法

Compliance verification involves checking design documents, product manuals, and certification records, combined with on-site inspections. Key evaluations include verifying the configuration of fire protection systems, measuring control airflow speeds using anemometers, and inspecting the setup of explosion-proof electrical equipment and anti-static grounding. Annual testing of ventilation performance and electrical safety parameters is required, along with the review of operational logs and maintenance records.

よくある質問

What products and facilities are regulated under GB 14444-2025?

It applies to the design, manufacturing, installation, commissioning, inspection, operation, and maintenance of spray booths using flammable or combustible liquid coatings. It is a mandatory national standard.

What are the main updates in GB 14444-2025 compared to the 2006 version?

The new edition removes certain obsolete terms and calculation examples, while adding specific requirements for dry-type spray booths, combustible dust explosion prevention, ventilation system interlocks with automatic spraying equipment, and human body static elimination devices. It also updates the control airflow speed design values.

How does GB 14444-2025 define explosion hazard zones?

The standard defines the spraying area as Zone 1, with adjacent areas classified as Zone 2 depending on the booth's opening configuration. Electrical equipment and lines must comply with the explosion protection requirements of GB 50058.
