2.5 ORDERING PRINCIPLES
Water supply system fittings are specific purpose industrial fittings, therefore orders must include:
- catalogue number (equivalent to face-to-face length),
- purpose, e.g. for water supply (or sewage) systems,
furthermore:
- nominal diameter — acc. to PN-EN ISO 6708: 1998
- nominal pressure — acc. to PN-89/H — 02650
- type of body material — acc. to PN-EN 1561: 2012 or PN-EN 1563: 2012
- max. operating temperature — acc. to PN-89/H — 02650.
