Requirements before the first shipment

Before the first shipment of any package, the following requirements shall 

In the design phase of the package, documents should be prepared to define how the requirements of para. 501 are fully complied with for each manufactured packaging. Each document required should be authorized (e.g. signed) by the persons directly responsible for each stage of manufacture. Specific values should be recorded, even when within tolerance. The completed documents should be retained on file in conformance with quality assurance requirements (see para. 310). 

Containment integrity should be assessed using appropriate leakage rate tests for compliance with para. 501(b) see paras 656.1-656.12 and 656.21-656.24. 

Inspection of a packaging for heat transfer characteristics, in compliance with para. 501(b), should include a dimensional check and special attention to ventilation apertures, surface emissivity, and absorptivity and continuity of conduction paths. Proof tests, which may normally be necessary only for a prototype package, may be conducted by using electrical heaters in place of a radioactive source.
