Backflow Insulation Requirements

In the 2017 OPSC, 603.4.7 freeze protection, it lists a reference standard for outdoor enclosures, ASSE 1060. Most enclosures we see are in ground enclosures. Short of buying the ASSE book, the only thing I've found online is with a manufacture for backflow covers, safe-t-cover. Does anyone have info on the ASSE 1060 standard, what class we are using for these type of in ground enclosures, and the minimum R-value for these type of enclosures?
