Field notes
The homepage groups its references into six sections, from Electrical and Machining to Music and Textile. Listed details include cable ampacity across 60, 75, and 90 °C columns, tap-drill recommendations for two thread-engagement levels, and washer dimensions under ISO 7089. The site says its figures come from published standards; that source claim is presented on the homepage, not independently verified in the supplied evidence.
