Overview
ISO/TS 15011-6:2012/Cor 1:2012 is a Technical Corrigendum to ISO/TS 15011-6:2012, part of the ISO/TS 15011 series on health and safety in welding and allied processes. It updates the laboratory procedure for sampling and quantitative determination of fumes and gases generated by resistance spot welding. Published 2012-09-15 by ISO/TC 44/SC 9, the corrigendum corrects welding parameter data (notably increasing the electrode force values by a factor of ten) in Table C.1 to ensure accurate, reproducible fume and gas measurements.
Key topics and requirements
- Scope: Laboratory method for sampling fume and gases specifically from resistance spot welding operations.
- Corrected welding parameters: The corrigendum amends the values in Table C.1 (electrode force column increased 10×). Table C.1 lists key parameters such as:
- Electrode force
- Weld time and hold time
- Sheet thickness (t)
- Electrode diameter
- Number of pulses and pause time
- Reference requirements: For coating-related X values the corrigendum refers users to ISO 18278‑2:2004, Table 5 (coating at the faying surface).
- Laboratory procedure: Emphasizes controlled, reproducible settings for resistance spot welding to obtain quantitative fume/gas data suitable for occupational exposure assessment, research, and test comparisons.
Applications and who uses it
This corrigendum (and the parent technical specification) is relevant for professionals who need standardized laboratory methods for measuring welding emissions:
- Industrial hygienists assessing worker exposure to welding fumes and gases.
- Welding engineers and metallurgists conducting emission testing during process development.
- Occupational safety and health (OSH) specialists implementing controls and compliance programs.
- Laboratories and test houses performing quantitative fume/gas analysis from resistance spot welding.
- Researchers studying fume generation, emission factors, and health impacts of welding processes.
Practical applications include development of emission profiles for specific materials/coatings, evaluation of ventilation and extract systems, comparative testing of electrode designs, and regulatory or compliance testing where reproducible lab methods are required.
