EN 15051-2:2013/FprA1

Workplace exposure - Measurement of the dustiness of bulk materials - Part 2: Rotating drum method

This European Standard specifies the rotating drum test apparatus and associated test method for the reproducible production of dust from a bulk material under standard conditions, and the measurement of the inhalable, thoracic and respirable fractions of this dust, with reference to existing European Standards, where relevant (see Clause 6).
This method is suitable for general bulk material handling processes, including all those processes where the bulk material is dropped, or can be dropped. It differs from the continuous drop method presented in EN 15051 3 in this European Standard, the same bulk material is repeatedly dropped, while in EN 15051 3, the bulk material is dropped only once, but continuously.
Furthermore, this European Standard specifies the environmental conditions, the sample handling and analytical procedures, and the method of calculating and presenting the results. A classification scheme for dustiness is specified, to provide a standardised way to express and communicate the results to users of the bulk materials.
This European Standard is applicable to powdered, granular or pelletised bulk materials. A standard sample volume is used.
This European Standard is not applicable to test the dust released when solid bulk materials are mechanically reduced (e.g. cut, crushed) or to evaluate handling procedures for the bulk materials.

Overview

EN 15051-2:2013/FprA1 is a CEN European Standard that defines the rotating drum method for measuring the dustiness of bulk materials. It specifies the test apparatus, sample handling, environmental conditions, analytical procedures and the way to calculate and present results for the reproducible production of dust under standard conditions. The method quantifies the inhalable, thoracic and respirable fractions generated from powdered, granular or pelletised materials. The 2016 draft amendment (FprA1) modifies test timing in Clause 5.7, clarifying a 1 min 5 s test sequence (5 s drum rotation with pump off, then 1 min with pump on) and post-test handling and reweighing of foams/filters.

Key Topics and Requirements

• Test apparatus and setup: Defines the rotating drum chamber and associated sampling outlets used to generate and collect airborne dust under controlled conditions.
• Fractional measurements: Requires measurement and reporting of inhalable, thoracic and respirable dust fractions in alignment with relevant European sampling conventions.
• Standard sample volume: Uses a defined sample volume for powdered, granular or pelletised bulk materials to ensure comparability.
• Environmental controls: Specifies laboratory environmental conditions (temperature, humidity, etc.) and controlled handling to minimise variability.
• Analytical procedures: Covers collection media (foams, filters), conditioning, weighing and calculation methods for dust mass and fractionation.
• Result presentation and classification: Includes a dustiness classification scheme for standardised communication of dust release potential.
• Scope limitations: Not applicable to dust generated by mechanical size reduction (cutting, crushing) or to evaluate specific handling procedures outside the controlled drop/rotation scenarios.

Applications and Users

• Occupational hygienists and workplace exposure assessors using dustiness data to model airborne concentrations and assess inhalation risk.
• Testing laboratories performing standardised dust generation and fractionation testing for powders, granules and pellets.
• Manufacturers and suppliers of bulk materials (chemicals, minerals, food powders, plastics) who need consistent dustiness classification for product stewardship and safety data sheets.
• Health & safety professionals and regulators setting controls for handling, storage and transport of dusty materials.

Related Standards

• EN 15051-3 (continuous drop method) - complementary method for materials dropped continuously rather than repeatedly in the same bulk.
• Other European standards on workplace atmospheres and sampling are referenced where relevant by EN 15051-2.

Keywords: EN 15051-2, rotating drum method, dustiness, bulk materials, inhalable thoracic respirable, workplace exposure, dust classification, test apparatus, sample handling.

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical
Committee CEN/TC 137.
This draft amendment A1, if approved, will modify the European Standard EN 15051-2:2013. If this draft becomes an
amendment, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for
