This International Standard applies to reinforced thermosetting resin pipe systems with nominal diameter (DN) 0 through 1 200 mm and nominal pipe sizes (NPS) 0 through 48, which are to be used in marine piping systems. Values stated in SI units are to be regarded as the standard. Values given in English units are for information only. The dimensionless designators DN and NPS have been substituted for traditional terms such as “nominal diameter”, “size”, and “nominal size” The following safety hazard caveat pertains to the test methods that are included in this International Standard. This standard does not purport to address all of the safety concerns associated with its use. SAFETY PRECAUTIONS —It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
