Technical guides for specifiers and contractors
Each guide answers one question, in the order an engineer asks it. They are written for use in a specification or a procurement review, not as marketing content.
Engineering notes
Published guides are listed newest first. Filter by topic to read the notes that match the decision in front of you.
One page, one question
Guides are added as questions come in from projects, exhibitions and sample orders, so the library grows around what specifiers actually need to decide.
Answers first
Each guide opens with the direct answer, then the working behind it. Parameters are tabulated rather than buried in prose.
Standards referenced
Where a standard governs a decision, it is named — principally IEC 60947-6-1 for changeover equipment and the IEC 61439 series for assemblies.
Published with an authority note
Every guide closes with a source and authority statement so a reader can see who maintains it and on what basis.
