EN ISO 11148-12:2012 PDF

Overview

EN ISO 11148-12:2012 (CEN adoption of ISO 11148-12:2012) sets safety requirements for hand‑held non‑electric power tools used for sawing - specifically circular saws, oscillating saws and reciprocating saws. It applies to tools powered by compressed air, hydraulic fluid or internal combustion engines and intended to be used by a single operator, hand‑held or suspended (e.g., balancer). The standard is a type‑C safety standard in the ISO 11148 series and addresses foreseeable use and misuse, excluding use in potentially explosive atmospheres and fixtures/mounted tool variants.

Key topics and technical requirements

EN ISO 11148-12:2012 covers the full lifecycle of saw tools with emphasis on practical safety measures and verification:

• Scope and definitions for circular, oscillating and reciprocating saw types (including jig saws, power hack saws, circular knives, oscillating knives and small-radius oscillating blades).
• Mechanical safety: guards, blade exposure, kickback prevention and constructional safeguards.
• Thermal safety: managing hot surfaces and heat generation during operation.
• Noise reduction and vibration requirements and methods for measuring and limiting operator exposure.
• Materials and emissions: handling of hazardous materials processed, used or exhausted by the tool.
• Ergonomics and controls: safe operator interfaces, start/stop controls and prevention of unintentional starts.
• Verification and testing: prescribed tests for noise, vibration, retractable lower guards, unintentional start and overall power tool construction.
• Information for use: marking, labels, warning signs, instruction handbook, maintenance and operating instructions required for safe use and conformity assessment.

Practical applications and users

This standard is essential for:

• Manufacturers and product designers of pneumatic, hydraulic or internal combustion driven saws to design compliant, safer products.
• Safety engineers and compliance officers who prepare risk assessments, technical files and conformity documentation.
• Test laboratories and certification bodies conducting verification tests (noise, vibration, guarding, start‑up safety).
• Procurement teams and site safety managers who specify safe hand‑held saws and evaluate vendor claims.
• Technical writers preparing user manuals, marking and maintenance instructions to meet regulatory expectations.

By following EN ISO 11148-12:2012 manufacturers demonstrate alignment with EU machinery requirements (2006/42/EC) and achieve a presumption of conformity within the standard’s scope.
