About this list

  • Titles are given as published, in the publication language. Relevance notes are original summaries and do not reproduce the content of the standards.
  • Edition and status. Entries marked as verified were checked against publisher information at the date shown. For the others, and in any case before placing an order, check the current edition with the publisher: standards are revised, amended and withdrawn, and ASTM standards carry a year suffix that changes frequently. European and national adoptions (EN ISO, DIN EN ISO, BS EN ISO, NF EN ISO, NEN-EN-ISO) may carry different dates from the ISO edition.
  • Contractual edition. Unless a dated edition is cited on the drawing or order, agree which edition applies.
  • Scope of the list. The list covers general industrial investment casting. Sector-specific specifications, for example for aerospace, pressure equipment, nuclear or medical applications, apply in addition and are not listed here.
