AS 2212-1979

Provides for hose and hose assemblies, classified in two types according to pressure, for handling anhydrous ammonia in liquid or gaseous form over a temperature range of -40 degrees Celsius to +65 degrees Celsius. The hose and hose assemblies have a particular use in agriculture. Constructional, dimensional and physical properties, and resistance to ammonia, low temperature and ozone are specified. In general, tests are prescribed by reference to AS 1180 but tests for resistance to ammonia and low temperature are described in appendices. A further appendix provides recommendations for periodical inspection, testing, handling and storage of hose and hose assemblies.

This standard specifies requirements for elastomeric hose and hose assemblies used for conveying anhydrous ammonia in liquid or gaseous form. It provides for hose up to and including 50 mm internal diameter.NOTES:1. Advice to hose users on periodical inspection and testing, and on handling and storage of hose and fittings is given in Appendix A.2. Appendix B provides guidance on the use of this standard in conjunction with statistical sampling and inspection schemes.
