Many hospital systems and university libraries provide their staff with site-wide access to the CLSI database [3].
Passing laboratory inspections requires documented proof that your media QC protocols follow recognized standards.
Here's some proper text on the topic:
The "A3" designation indicates this is the third edition of the "A" (Approved) standard. It streamlines laboratory workflows by identifying which types of commercially prepared media require intensive user QC and which can rely on the manufacturer’s QC documentation. Key Content of the Standard

The standard's core principle is that the retesting of commercially prepared microbiological culture media is unnecessary for those media that have demonstrated proven reliability. The categorization of media that do not require retesting by the user is based on quality control data collected from surveys of clinical laboratories enrolled in the bacteriology proficiency-testing program conducted by the College of American Pathologists (CAP). These media types are well established for the recovery of clinically significant microorganisms. The standard applies to all commercial media listed in Table 2 of the document, regardless of packaging, plate, or tube design.
