IEC 62841-2-5:2014

Overview - IEC 62841-2-5:2014 (Part 2‑5)

IEC 62841-2-5:2014 specifies safety requirements for electric motor‑operated hand‑held circular saws (hereafter “saws”). It is a particular part of the IEC 62841 series and is to be read in conjunction with IEC 62841-1:2014. The standard addresses hazards encountered in normal use and reasonably foreseeable misuse of hand‑held circular saws and transportable combinations (hand‑held saws mounted on supports). It excludes saws designed for abrasive wheels (these are covered by IEC 62841-2-22).

Scope limits include:

• Rated voltage not more than 250 V for single‑phase a.c. or d.c., and 480 V for three‑phase a.c.
• Rated input not more than 3 700 W
• Battery tool applicability and limits given in Annex K

The committee recommends a transitional adoption period (not earlier than 36 months from publication) to allow manufacturers and test labs to implement new requirements.

Key topics and technical requirements

This Part 2‑5 supplements IEC 62841-1 with circular saw‑specific provisions. Key topics include:

• Guarding system requirements (upper guard, lower guard, base plate, riving knife) and performance tests
• Kickback hazards - definitions and protective measures (mechanical design and guards)
• Mechanical hazards - blade exposure, cutting edge zone, plunge‑type saw considerations
• Starting, input and current, heating, overload and endurance tests to ensure safe operation under normal and abnormal conditions
• Protection against access to live parts and insulation/earthing provisions
• Noise and vibration measurement (Annex I) and battery tool requirements (Annex K)
• Specific annexes: riving knife (Annex AA), lower guard for saws without riving knife (Annex BB)
• Marking and instructions, test conditions, mechanical strength and construction requirements

Figures and dimensional requirements (e.g., base plate geometry, guard clearances, blade exposure angles) are provided to standardize safety margins and testing.

Applications - who uses this standard

IEC 62841-2-5 is essential for:

• Circular saw manufacturers (design, verification, technical files)
• Test laboratories and certification bodies performing safety and conformity testing
• Regulatory authorities and procurement teams specifying safe tools for workplaces
• R&D and safety engineers designing cutting tools and guarding systems
• Compliance professionals preparing user manuals, markings and safety instructions

Applying this standard helps reduce cutting‑related incidents (kickback, blade contact), ensures product conformity, and supports market access in regions adopting IEC/EN requirements.
