EN ISO 11148-8:2011 PDF

Overview

EN ISO 11148-8:2011 - "Hand-held non-electric power tools - Safety requirements - Part 8: Sanders and polishers" is a type‑C safety standard published by CEN/ISO. It specifies safety, verification and information‑for‑use requirements for hand‑held non‑electric sanders and polishers used for polishing and sanding with rotary, orbital or reciprocating motion. Covered tools include belt sanders, orbital sanders, polishers, random orbital sanders, rotary sanders and straight‑line sanders powered by compressed air, hydraulic fluid or internal combustion engines (operator‑held, single‑operator use).

The standard addresses all significant hazards when tools are used as intended or under reasonably foreseeable misuse, except use in potentially explosive atmospheres and fixture‑mounted special modifications.

Key Topics

• Scope and definitions: Tool types, movements and intended use; normative terminology aligned with ISO vocabulary documents.
• Mechanical safety: Requirements to reduce risks from rotating/reciprocating parts, abrasive product retention and flying debris.
• Thermal safety: Measures related to hot or cold surfaces and operator contact.
• Noise and vibration: Guidance on noise reduction, vibration control and test methods for emission measurement.
• Materials and emissions: Consideration of hazardous substances produced or used during sanding/polishing.
• Ergonomics and controls: Design for safe handling, controls to prevent unintentional start and instructions for safe operation.
• Verification and testing: Test conditions and methods for noise, vibration, structural integrity and unintentional start.
• Information for use: Marking, labelling, instruction handbook, maintenance and operating instructions.
• Annexes: Lists of significant hazards, examples of covered tool types, symbols for labels and examples of abrasive products.

Applications and Users

EN ISO 11148-8:2011 is practical for:

• Manufacturers and designers developing compliant pneumatic/hydraulic hand‑held sanders and polishers.
• Product safety engineers performing risk assessments and implementing mitigation measures.
• Test laboratories verifying noise, vibration and mechanical safety according to referenced test methods (e.g., ISO 28927 series).
• Technical purchasers and maintenance teams requiring specification and safe‑use information.
• Conformity bodies and notified bodies assessing compliance with the Machinery Directive (2006/42/EC) where this standard provides a presumption of conformity for applicable essential requirements.

Practical uses include product design validation, creating instruction manuals, defining protective measures in workshops and supporting CE marking and regulatory compliance.

Related Standards

EN ISO 11148-8:2011 is part of the ISO 11148 series (hand‑held non‑electric power tools) and references general standards such as:

• ISO 12100 (risk assessment and risk reduction),
• ISO 28927-3 (vibration test methods for polishers and sanders),
• other ISO vocabulary and measurement standards for noise, ergonomics and hydraulic/pneumatic tools.
