Overview
IEC 60335-2-94:2008 is the IEC product-family safety standard for electric powered scissors type grass shears (hand‑held), supplementing IEC 60335-1. It applies to appliances designed primarily for cutting grass with a maximum cutting width of 200 mm and rated voltages of not more than 250 V a.c. or 50 V d.c. The third edition (2008) updates requirements on mechanical hazards, construction, endurance and resistance to rusting. EMC and environmental aspects are not covered except for noise.
Keywords: IEC 60335-2-94, grass shears safety standard, scissors type grass shears, electric grass shears safety, cutting width 200 mm.
Key Topics
The standard defines safety requirements, tests and documentation relevant to scissors type grass shears, including:
- Scope and definitions tailored to grass shears (hand‑held scissors type).
- General safety requirements from IEC 60335-1, as supplemented or modified.
- Mechanical hazards and stability (e.g., cutting means strength, mechanical strength, protection against access to moving parts).
- Electrical safety: leakage current, electric strength (dielectric), protection against live parts, starting and overload protection.
- Endurance and abnormal operation tests to verify long‑term reliability and safe behavior under fault conditions.
- Construction and materials: guidance on corrosion resistance (rusting) and component integrity.
- Human factors, marking and instructions: required labeling, instructions and symbols for safe use.
- Noise and vibration: measurement references and methods (ISO/IEC references included).
- Test and measurement topics listed in the standard’s clauses and annexes (e.g., moisture resistance, heating, terminals, wiring).
Applications and Who Uses It
IEC 60335-2-94 is used by:
- Manufacturers and product designers to validate safety in new electric scissors type grass shears.
- Test laboratories and conformity assessment bodies performing type and routine testing.
- Regulatory authorities and certification bodies for market surveillance and approval.
- Compliance engineers and technical authors preparing user manuals, warnings and markings.
- Procurement and quality teams for supplier specification and audit criteria.
Practical uses include product design validation, risk assessment, preparing technical documentation for CE/market entry, and ensuring compliance with recognized international safety practices.
