EN ISO 17652-4:2003 PDF

Overview

EN ISO 17652-4:2003 is a European and international standard that specifies the requirements and test methods for evaluating the influence of shop primers on the emission of fumes and gases during welding and allied processes. Developed and maintained by CEN in collaboration with ISO Technical Committee 44, this standard focuses specifically on Part 4 of a series addressing shop primers used in welding environments.

The standard outlines how to prepare test pieces coated with shop primers and provides a systematic procedure for measuring and analyzing the emission rates of fumes and gases generated during welding. It aims to support occupational health professionals by offering standardized data to assess environmental and health impacts in welding workplaces.

Key Topics

• Scope Defines rating criteria for shop primers regarding their effect on fume and gas emissions during welding.

• Test Piece Preparation

  • Mild steel plates (S275 according to EN 10025) sized 10 mm x 100 mm x 500 mm
  • Abrasive blasting to remove mill scale (Sa 2½)
  • Application of shop primer with uniform thickness per manufacturer’s instructions
  • Reference specimens without shop primer for baseline emissions comparison

• Welding Procedure

  • Metal Active Gas Welding (MAG), process 135 (EN ISO 4063)
  • Specific welding parameters including current (250 A ± 5%), voltage (28-30 V ± 5%), and speed (300 mm/min ± 5%)
  • Shielding gases: either 100% CO or a mixture of 82% Ar, 18% CO₂ (EN 439)
  • Use of wire electrodes classified G3Si1, diameter 1.2 mm (EN 440)

• Emission Testing and Analysis

  • Fume box technique compliant with EN ISO 15011-1 and prEN ISO 15011-2 for sampling fumes and gases
  • Analysis for key chemical elements (Fe, Mn, Zn, Cu, Pb, Cr, F) and gases (NO, NO₂, CO)
  • Calculation of average emission rates for primer-coated versus uncoated test pieces
  • Determination of emission changes attributed to shop primers

• Reporting Requirements

  • Detailed test report including shop primer details, welding setup, observed film thickness, emission rate changes, and environmental impact assessment
  • Documentation to assist compliance with health, safety, and environmental regulations

Applications

EN ISO 17652-4:2003 serves multiple practical applications within welding, manufacturing, and occupational health fields:

• Occupational Hygiene Enables industrial hygienists to assess potential health hazards related to fumes and gases when welding coated materials.

• Quality Control in Fabrication Shops Assists fabricators and quality managers to select shop primers with minimal harmful emissions, improving workplace safety.

• Environmental Compliance Supports regulatory compliance by providing standardized emission data to meet national environmental and workplace safety laws.

• Primer Development and Certification Allows coating manufacturers to evaluate and certify their shop primers for low emission properties during welding processes.

• Safety Risk Assessment Facilitates risk evaluations linked to welding of coated metals by quantifying harmful fume and gas output influenced by primers.
