Quality, testing and certification

Every lot traces back to its heat. Every certificate says what was measured, not what was intended.

What a certificate states

The difference between a document and a claim.

  • The heat number the material came from.
  • The measured diameter, next to the tolerance it had to meet.
  • The measured resistivity or EMF, next to the minimum or the class.
  • Tensile and elongation results for the lot.
  • The standard the lot was tested against, named by number.

If something does not meet the specification

It is found before the spool ships, or it is declared.

A lot outside the tolerance is not shipped as if it were inside. Either it is reworked and re-measured, or the deviation is stated before delivery so the buyer can decide whether it is usable. A deviation found after delivery costs both sides more than a conversation before it.
