Supplier qualification
Provisions
Material is obtained and analysed before any commitment; a supplier is judged on what it sends, not what it says
The certificate presented must correspond to the batch actually shipped; a generic product certificate, one with no batch identifier, or one whose batch does not match the vials is disqualifying
The supplier's own certificate is treated as a claim to be checked, not as evidence
Qualification does not carry forward: every batch is analysed on arrival regardless of how the previous one performed
Requalification is triggered by any change of source, process or specification
Scope. This document forms part of the Lyze Labs quality system and applies to
research reference material supplied for in vitro laboratory use. It is not a
marketing authorisation, a regulatory approval, or a claim that material may be used
in humans.

an external body. A superseded revision is archived rather than destroyed, so what was
in force on any given date can be established.
