The short regulatory answer is 49 CFR 173.127. The better regulatory answer is the UN Manual of Tests and Criteria, Third Revised Edition (1999). That is the standard; you need someone to test in accordance with the standard. We have used Stresau Labs is the past based on recommendations from other organizations and enjoyed the experience.
I would be very careful if attempting to extrapolate or interpret data from other test standards (SW-846, etc.) or other tests (strips or wet chemistry). Being slightly musical, it don’t mean a thing if it ain’t got that swing. DOT will look at testing personnel (especially experience), testing procedures, and testing equipment to ensure the results are in accordance with UN standards (The Orange Book).

Subject: [DCHAS-L] Testing company for oxidizer determination
We have a colleague with the following question. Can anyone point him in the direction of a testing lab or other expert that can make the determination?
You can reply directly to me and I will collate the responses and post them to the list in a single post.
Where can I send a sample of liquid to have a determination done as to classification for shipping/storage/handling purposes as to whether it is an oxidizer?
It is essentially a suspension of zinc oxide, with some sodium nitrate.
