Material certificate

Grade and thickness, traceable to the batch

Last specification

The five measurements and the tolerance each is held to

Size record

Which sizes were measured and how many pairs of each

Pairing record

Left against right, because a per-nominal tolerance does not cover it

Bond test record

Strength and how it was measured, on samples

Weight record

Per pair, because a stack that gains weight has drifted

Revision statement

Which last revision the run was graded from

Interchangeability statement

What the component fits, and what it does not

An illustrative list for a fictional range. A real programme agrees which documents are required, in what form, and how long they are retained.

The one that is most often missing.

The pairing record. A tolerance quoted per nominal leaves the one thing a wearer actually experiences, and it cannot be reconstructed after the pairs are boxed.

Why the bond record is a strength and not a yes.

Because a bond either holds or it does not. A statement that the sole is attached describes a join; a strength figure describes how much load it takes.
