Overview
EN ISO 11148-5:2011 - Hand‑held non‑electric power tools - Safety requirements - Part 5: Rotary percussive drills (ISO 11148-5:2011) is a CEN-adopted ISO standard that specifies safety requirements for hand‑held, non‑electric rotary percussive drills used to make holes in hard materials (rock, concrete). It applies to plug‑hole drills, rock drills and rotary hammers powered by compressed air, hydraulic fluid or internal combustion engines, intended for single‑operator hand support (with or without a balancer). The standard addresses foreseeable misuse but excludes equipment for potentially explosive atmospheres.
Key topics and requirements
EN ISO 11148-5:2011 focuses on minimizing significant hazards throughout the tool lifecycle. Major technical topics include:
- Hazard identification and risk reduction for rotary percussive drills (see informative Annex A).
- Mechanical safety: guarding, retention of inserted tools and structural integrity.
- Thermal safety: prevention of hazardous hot or cold surface contact.
- Noise reduction: requirements and measurement methods for declared noise emission (references ISO 15744).
- Vibration control: emission measurement and declaration methods (references ISO 28927-10, EN 12096).
- Controls and start/stop devices: ergonomic placement, hold‑to‑run and throttle design to prevent unintentional start.
- Materials and emissions: guidance on hazardous substances produced, used or exhausted.
- Ergonomics: design for operator safety and comfort, including balance and suspensions.
- Verification and testing: defined test conditions for noise, vibration, unintentional start and construction checks.
- Information for use: marking, labels, instruction handbook content, operating and maintenance instructions (detailed in Clause 6 and Annexes).
- Special provisions: normative annexes include symbols for labels and additional requirements for internal combustion engine versions.
Applications
This standard is used to ensure safe design, manufacture, testing and documentation of hand‑held rotary percussive drills in construction, mining, civil engineering, tunnelling and quarrying. Practical uses include:
- Developing compliant product designs and user manuals.
- Performing conformity testing and issuing vibration/noise declarations.
- Preparing procurement specifications and safety assessments.
- Guiding maintenance procedures and operator training.
Who should use this standard
- Tool manufacturers and product designers
- Safety and compliance engineers
- Test laboratories and certification bodies
- Procurement specialists and asset owners (construction, mining)
- Technical writers preparing instruction handbooks
