Standard: 2016
Section: V1M2, Section 5.6.4.2 (d)
REQUEST:
"All containers of prepared standards, reference materials, and reagents shall bear a unique identifier and expiration date."
If the reagent is from the same lot but came in multiple bottles, do they need a unique ID? For example, if a case of Methylene Chloride came in a pack of 4 bottles, can all 4 bottles share the same ID or do they need to be distinguished despite having the same manufacturer lot number?
TNI FINAL RESPONSE:
For the example given, each container does not require a distinct unique identifier. Clause 5.6.4.2 d) refers to standards, reference materials, and reagents prepared in the laboratory, not original containers received from the manufacturer or vendor.
