ISO 17652-1:2003

Overview

ISO 17652-1:2003, titled Welding - Test for shop primers in relation to welding and allied processes - Part 1: General requirements, is an international standard developed by ISO in collaboration with CEN. It establishes standardized conditions and general requirements for assessing the weldability of steel materials coated with shop primers.

Shop primers are corrosion-protective coatings applied during steel fabrication to protect metal surfaces prior to final painting or use. This standard facilitates the evaluation and quality control of these primers with respect to their impact on welding processes. It is essential for suppliers and customers to ensure that shop primers do not impair welding quality or introduce welding defects.

The document supports consistent testing and communication by serving multiple roles:

• Development and quality control of new and existing shop primers by suppliers
• Declaration of shop primer performance characteristics
• Reference basis for contractual specifications between suppliers and customers
• Comparative evaluation of different primers or welding procedures

Key Topics

• Shop primer assessment: Provides standardized test methods to evaluate the compatibility of primers with welding processes.
• Welding procedure compatibility: Enables comparison between different welding techniques using a given primer, or comparisons between primers using standard welding procedures.
• Quality control: Supports suppliers in monitoring primer batches to maintain consistent weldability.
• Test types: Includes rating tests (porosity and weldability screening), weldability tests (energy and heat impact), and considerations regarding thermal cutting and emissions in related parts of the ISO 17652 series.
• Health, safety, and environmental considerations: Emphasizes precautions related to solvent emissions during primer application and fumes emitted during welding or cutting.

Applications

ISO 17652-1:2003 is applicable across various industrial sectors involving steel fabrication and welding processes, including:

• Steel fabrication shops: Ensuring primers used on structural steel do not hinder welding operations.
• Automotive and heavy machinery manufacturing: Verifying primer suitability for welding assembly lines.
• Construction and infrastructure: Assessing corrosion protection primers for steel elements that require welding during erection or maintenance.
• Supplier-customer contracts: Providing clear acceptance criteria and test references for primer deliveries and usage.
• Research and development: Guiding formulation testing of new shop primers for weldability performance.

By adhering to this standard, organizations can optimize welding operations, reduce defects such as porosity and cracking, and enhance the overall durability and corrosion resistance of steel components coated with shop primers.

Related Standards

ISO 17652-1 is part of a series that addresses various aspects of shop primers and welding processes, including:

• ISO 17652-2:2003 – Welding properties of shop primers: Detailed weldability tests, including rating and weldability assessments.
• ISO 17652-3:2003 – Thermal cutting: Evaluates the influence of primers on thermal cutting operations and quality.
• ISO 17652-4:2003 – Emission of fumes and gases: Addresses the evaluation of fume and gas emissions generated during welding of primed steel.

Additional related standards supporting corrosion protection in steel fabrication include:

• EN ISO 12944 Series: Covers corrosion protection coatings, surface preparation, and paint system execution for steel structures.
• EN 10238: Deals with automatically blast-cleaned and prefabricated primed structural steel products.

Summary

ISO 17652-1:2003 provides a comprehensive framework for the assessment and testing of shop primers used on weldable steel materials. It ensures that primers used during fabrication do not compromise welding quality or pose undue health, safety, or environmental risks. This standard is a valuable tool for manufacturers, suppliers, welders, and quality professionals to maintain high standards of weldability and corrosion protection in steel fabrication industries.
