There are of course the technical standards you need, so having them available, having folks trained, taking care of the test samples, controlled environment, and technical records, are all part of normal lab operations.....
To go beyond that for a more complete lab management, then obtain a copy of ISO/IEC 17025 and begin to implement that, including theprocess and documentation structures, and lab management involvement and oversight.....
Once you are ready, since you are in China, contact one of your accrediting bodies, CNAL or HKAS, to complete the accreditation process.
Hope this helps.
