BS 4993-3 guides you on the procedure and calculation

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

bridge restraints and a few other selected topics

as confirmed by thermal resistance and thermal conductivity tests

How does it work

Resistance spot-, projection- and seam-welding. Method for determining the transition resistance on aluminium and steel material Ingestion-build-141043 BS 4993-3 guides you on1 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.
