NOTE 1 For applications operating at constant temperatures greater than 20°C and up to 40°C, see annex A of EN 12201-1:2001 EN 12201 covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes. These fittings can be of the following types: - fusion fittings; - butt fusion fittings; - socket fusion fittings (see annex A) - electrofusion fittings; - mechanical fittings; - compression fittings; - flanged fittings.
