    Abstract - (Show below) - (Hide below)

    ISO 1167-1:2006 specifies a general test method for determining the resistance to internal hydrostatic pressure at a given temperature of thermoplastics pipes, fittings and piping systems for the transport of fluids. The method accommodates water-in-water, water-in-air and water-in-liquid tests.
