IEC 62841-2-7:2024

Overview

IEC 62841-2-7:2024 is an international standard developed by the International Electrotechnical Commission (IEC) setting out specific safety requirements for electric motor-operated hand-held spray guns designed for non-flammable materials. This standard addresses tools with a rated voltage not exceeding 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools, with rated input not more than 3,700 W. It is intended for all users involved with spray guns in both domestic and professional settings.

This standard supplements IEC 62841-1:2014, which provides general safety requirements for electric motor-operated hand-held tools, transportable tools, and lawn and garden machinery. IEC 62841-2-7:2024 aims to mitigate hazards that could arise from normal and reasonably foreseeable misuse of hand-held spray guns, and is essential for manufacturers, testing organizations, regulatory bodies, and professionals concerned with electric tool safety.

Key Topics

Coverage and Scope

• Applies to electric and magnetically driven hand-held spray guns for non-flammable materials.
• Covers safety risks during anticipated regular use and foreseeable misuse.
• Specifies rated voltage and power limitations:
  • Up to 250 V for single-phase a.c./d.c. tools
  • Up to 480 V for three-phase a.c. tools
  • Maximum rated input: 3,700 W
• Defines the applicability for battery tools, further detailed in Annex K (battery tools and packs) and Annex L (battery tools with mains connection).

Exclusions

• Does not apply to tools for explosive atmospheres, medical usage, food preparation, cosmetics, pharmaceutical use, or industrial machine-tool equipment.
• Not intended for household appliances covered by IEC 60335 or similar standards.

Modifications to General Requirements

• Supplements and modifies clauses in IEC 62841-1 as they pertain specifically to hand-held spray guns.
• Contains additional or specialized requirements addressing:
  • Protection from live parts
  • Marking, instructions, and user information
  • Overload protection, mechanical hazards, and safety testing for specific applications

Transitional and Implementation Guidelines

• Recommends a national implementation period of not less than 36 months from the date of publication for manufacturers and testing organizations to adapt to the new or revised requirements.

Applications

Manufacturers and Designers

• Essential reference for manufacturers during product design, development, and conformity assessment of electric spray guns.
• Ensures compliance with international safety benchmarks, facilitating market access and regulatory approval.

Testing Laboratories and Certification Bodies

• Provides standardized methods and requirements for testing electrical, mechanical, and operational safety.
• Supports harmonization in conformity assessment procedures across markets.

Occupational Safety

• Guides occupational health and safety practitioners in assessing compliance of hand-held spray guns used in maintenance, painting, and construction.
• Reduces potential injury or accidents related to electrical shocks, overheating, mechanical faults, or unintended operation.

National and International Market Access

• Assists organizations in aligning with global best practices, enhancing product acceptance in multiple regions.
• Key reference for governments and regulators updating or developing electrical safety regulations for hand-held tool categories.
