This Gulf standard is concerned with specifying the general properties of polyethylene materials used for coating steel pipes used for the transportation of liquid and gaseous fluids. It is intended to be used for quality assurance purposes. When supplied with normal type coatings (N), pipes in compliance with this standard are suitable for continuous service temperatures of up to 50°C, and with special type coatings (S), for temperatures up to 70°C. For the purposes of this standard, the term 'steel pipe' includes fittings manufactured from such pipes.
