Overview
ISO 11148-3:2012 - Hand-held non-electric power tools - Safety requirements - Part 3: Drills and tappers - specifies safety requirements for hand-held non-electric drills and tappers. It applies to rotary drilling, tapping and thread-cleaning operations in materials such as wood, metal, concrete and plastics. Covered power sources include compressed air (pneumatic), hydraulic fluid, and internal combustion engines. The standard is a Type C standard (per ISO 12100) and addresses significant hazards when drills and tappers are used as intended or under reasonably foreseeable misuse (excluding use in potentially explosive atmospheres).
Key Topics and Technical Requirements
ISO 11148-3:2012 sets out technical safety requirements and verification measures, including:
- Mechanical safety: requirements for surfaces, edges, stability, chucks and service tools to reduce cutting and contact hazards.
- Control devices and start/stop functions: definitions and safety for hold-to-run, lock-on, lock-off and positive on-off throttles to prevent unintentional starts.
- Thermal safety: protection against hot or cold surfaces and related ergonomic guidance.
- Noise and vibration: provisions for measuring, declaring and reducing noise and vibration emissions (references include ISO 15744, ISO 20643 and ISO 28927-5 for test methods).
- Materials and emissions: considerations for materials and substances processed, used or exhausted by the tool.
- Ergonomics and human factors: design guidance to reduce operator strain (including suspension devices and two-handle heavy‑duty drills).
- Verification and testing: test conditions and verification clauses for noise, vibration, unintentional start and power tool construction.
- Information for use: marking, warning signs, operating and maintenance instructions, and data requirements.
- Annexes: lists of significant hazards, examples of covered tools, symbols for labels, and additional requirements for internal combustion powered tools.
Practical Applications and Who Uses This Standard
ISO 11148-3:2012 is used by:
- Manufacturers of pneumatic, hydraulic and combustion-driven drills and tappers to design and certify compliant products.
- Product safety engineers and designers implementing risk reduction measures per ISO 12100.
- Test laboratories and certification bodies conducting noise, vibration and safety verifications.
- Procurement and compliance officers specifying safe hand-held non-electric power tools for industry (construction, metalworking, maintenance).
- Maintenance teams and trainers who rely on standardized instructions for safe operation, servicing and hazard communication.
Using this standard helps reduce operator injuries, improve ergonomics, and ensure regulatory and market acceptance for non-electric hand-held drilling and tapping tools.
