COATING INFORMATION:
Hydrant Risers available coated with a thermal bonded polymeric coating system in accordance with AS4158. This standard specifies a minimum film thickness and performance characteristic to ensure continuity in the coating and subsequent product. The following table identifies the critical coating thickness requirement of AS4158 for both types of standard thermal coating systems in use in the Australian water industry.

Coating Type	Internal Surfaces	External Surfaces
Thermoplastic (RN11)	250um	200um
Thermoset (FBE)	350um	300um
Note. um = microns (film thickness)
