Resistance spot-, projection- and seam-welding. Method for determining the transition resistance on aluminium and steel material Ingestion-build-141043 Note 2: BS EN 523

Note 2: BS EN 523 does not cover plastic sheaths

International Machinery Directives require that manufacturers of escalators and moving walkways ensure testing of their products before placing them into service or after any major modifications as clearly there is a risk of harm to users if either are installed or manufactured incorrectly

BS EN 755-3:2008 Aluminium and aluminium alloys

The modifications included in this standard are not a change of test criteria

Resistance spot-, projection- and seam-welding. Method for determining the transition resistance on aluminium and steel material Ingestion-build-141043 Note 2: BS EN 5231 Scope This International Standard specifies the procedure and the experimental set up for determining the transition resistance of a single sheet or two overlapping sheets of aluminium or steel, with or without surface treatment, and with or without surface coating.
