Updates to the AOSA Purity Testing Handbook (2020)
The AOSA Purity Testing Handbook (PTH) is available for purchase under the Store tab of this website. Understanding the AOSA Rules and the uniform application of the procedures provided in the AOSA Rules is the goal of the PTH. This handbook is not meant to be a substitute for the AOSA Rules and should not be relied upon as such. As a reminder, whenever there is a conflict between the AOSA Rules and what is stated in this handbook, the AOSA Rules always prevail.  Periodic updates to the PTH will be posted here for free download.
