Elektromotorna orodja - Postopek meritve prahu - 2-1. del: Posebne zahteve za svedre in udarne svedre

Ta evropski standard določa splošne zahteve za meritve prahu elektromotornih orodij, ki se napajajo iz omrežja ali baterij. Ta evropski standard velja za tista orodja, pri katerih se pričakuje nabiranje prahu (na primer mineralnega prahu, ki vsebuje kremenico, ali lesnega prahu), ne glede na to, ali so opremljeni z enoto za izločevanje prahu ali ne.

Overview

SIST EN 50632-2-1:2015 is a European standard developed by CLC focusing on the dust measurement procedures for electric motor-operated tools, specifically targeting diamond core drills. This standard complements Part 1 of EN 50632 by addressing particular requirements and modifications necessary to accurately assess dust emissions from diamond core drilling operations. It aims to provide consistent and reliable methods to measure the inhalable and respirable dust generated during the drilling process, which is critical for assessing occupational safety and health risks.

This standard applies to diamond core drills designed to operate with or without water supply, capable of drilling with or without percussion, primarily into materials such as concrete and brick. The test methods and conditions outlined ensure accurate dust measurement and facilitate compliance with safety regulations related to dust exposure.

Key Topics

• Scope and Applicability
  EN 50632-2-1 applies specifically to diamond core drills, supplementing the general dust measurement procedures covered in Part 1 of EN 50632. It defines the unique testing conditions needed for these tools.

• Test Procedure and Operating Conditions
  Diamond core drills are tested under load using calcium silicate blocks as the test material.

  • Blocks must have a density between 1800 and 2000 kg/m³, thickness of at least 100 mm, and compressive strength of ≥ 20 N/mm².
  • Blocks are arranged on an A-support inclined at 15°, with specific height and orientation.
  • Drilling involves creating 20 holes of 40 mm depth within a 10-minute cycle.
  • A new drill bit of 82 mm diameter is used for each test, with speed settings adjusted according to manufacturer specifications.
  • Feed force must ensure stable tool operation and optimal drilling performance.

• Instrumentation and Measurement Parameters
  Dust measurement instruments are specified as in Part 1, focusing on inhalable and respirable dust concentration. EN 50632-2-1 requires reporting the mean value of respirable dust concentration, plus any cycle time extension if 20 holes cannot be completed within 10 minutes.

• Reporting Requirements
  Reports must include detailed operational conditions, dust concentration results, and any deviations such as extended drilling cycles. This enhances transparency and facilitates comparison across tests and products.

Applications

The standard is intended for manufacturers, testing laboratories, safety officers, and regulatory bodies involved with:

• Occupational Health and Safety Compliance:
  Ensuring diamond core drills meet dust emission limits to protect workers from harmful particulate exposure.

• Product Development and Quality Control:
  Guiding manufacturers in assessing dust emissions during tool design and production to improve safety features like dust extraction systems.

• Certification and Market Access:
  Supporting conformance assessments needed for CE marking and market entry within the European Union and other territories adopting EN standards.

• Risk Assessment and Workplace Monitoring:
  Providing a benchmark methodology for identifying and mitigating dust exposure risks when using diamond core drilling equipment on construction sites and industrial facilities.

Related Standards

• EN 50632-1:2015 – General requirements and procedures for dust measurement in electric motor-operated tools, serving as the foundational document for Part 2-1.

• ISO and CEN Safety Standards on Respiratory Protection and Dust Exposure – Complementary guidance on workplace dust limits and protective equipment.

• EN 60745 Series – Safety requirements for handheld motor-operated electric tools.

By following SIST EN 50632-2-1:2015, stakeholders can ensure accurate dust measurement tailored to diamond core drills, fostering safer work environments and supporting compliance with European safety directives.
