Overview
EN 50632-1:2015 is a European standard developed by CLC that defines the general requirements for dust measurement procedures in electric motor-operated tools. These tools, powered either by mains or batteries, are commonly used in environments where dust, including hazardous mineral dust containing silica or wood dust, is generated during operation. This standard focuses on measuring dust emissions to ensure operator safety and workplace air quality.
The standard applies to tools with or without dust extraction units, providing a consistent method for assessing dust concentration produced by these tools under standardized conditions. It aims to quantify inhalable and respirable dust fractions, important metrics for evaluating health risks associated with airborne particles during tool operation.
Key Topics
Scope and Dust Types
EN 50632-1 distinguishes two key dust size fractions based on EN 481 classifications:- Inhalable dust - dust particles that enter the mouth or nose and can be breathed into the respiratory system.
- Respirable dust - finer particles capable of reaching the pulmonary alveoli, posing greater health risks.
Test Environment and Procedures
Dust measurements must be conducted in a controlled test room meeting specified criteria:- Minimum 200 m³ volume and adequate spacing (≥ 2 m) from walls to prevent dust accumulation bias.
- No external air pollution sources or ventilation during tests.
- Ambient temperature maintained at 20° ± 5°C and relative humidity ≤ 75%.
Testing involves skilled operators simulating typical tool use, with standardized work and rest cycles totaling at least one hour.
Instrumentation and Accuracy
The standard mandates high-precision instruments for measuring voltage, speed, temperature, and humidity to ensure test consistency. Dust samplers compliant with EN 13205 must accurately capture inhalable and respirable dust.Dust Extraction Units
The document covers both integral and external dust extraction devices used alongside tools. It specifies how to evaluate their airflow rate, vacuum pressure, and dust collection efficiency during testing periods.Reporting Requirements
Detailed documentation is mandatory, covering:- Tool specifications and used accessories
- Test materials and operating conditions
- Dust extraction system descriptions and measurements
- Measurement results with statistical analysis including uncertainty calculations
- Environmental and instrumentation data
This structured reporting ensures test reproducibility and comparability across different laboratories.
Applications
EN 50632-1:2015 serves as a foundational standard useful for:
- Manufacturers assessing and declaring dust emission levels of electric motor-operated tools.
- Test laboratories conducting standardized dust concentration measurements to support product certification.
- Workplace safety professionals performing preliminary assessments of dust exposure risks in occupational environments.
- Regulatory bodies establishing compliance frameworks for occupational health and safety relating to airborne dust from power tools.
- Designers of dust extraction systems validating the effectiveness of dust control attachments under controlled conditions.
By following EN 50632-1, stakeholders can compare dust emissions reliably, optimize dust control technologies, and reduce health hazards linked to silica and wood dust exposure in industrial and construction settings.
Related Standards
The EN 50632-1:2015 standard is to be used alongside specific parts that address particular tool types and supplementary requirements:

Introduction
Inhalable dust emitted by electric motor-operated tools may present a hazard to the operator and
other exposed persons.
Therefore, this standard specifies a procedure how to measure the dust concentration produced by an
electric power tool under standardized conditions representing typical applications. However, the dust
concentration during actual use of the power tool may differ from the dust concentration measured in
accordance with this standard depending on the ways in which the tool is used.
The results of dust measurements can be used:
- for a declaration of the dust emission;
- for comparing the dust emission from tools of the same type;
- in a preliminary assessment of dust exposure at a workplace.
For all purposes, it is important to specify measurement procedures with known accuracy so that the
results of measurements taken by different laboratories can be compared.
The measurements of dust concentration are made in accordance with the standard EN 1093-9 for
the test room.
1 Scope
1.1 General
This European Standard specifies general requirements for the dust measurement of electric motor-
operated tools supplied from mains or from batteries. This European Standard applies to those tools
with and without dust extraction unit where dust such as mineral dust containing silica or wood dust
is expected.
1.2 Types of dust
Dust is a disperse distribution of solid substances in gases, particularly air, resulting from mechanical
processes. According to EN 481, two size categories are to be differentiated: the inhalable dust and
the respirable dust fraction. Inhalable dust refers to the entire inhalable fraction of the dust through
mouth and/or nose. Respirable dust relates to the fraction of the inhalable dust that can reach the
pulmonary alveoli due to its small particle size.
