ISO 6594:2006 PDF

Overview

ISO 6594:2006 - Cast iron drainage pipes and fittings - Spigot series - specifies the technical characteristics, dimensions and test methods for cast iron drainage systems used for waste and sewage discharge, rainwater downpipes and ventilation pipe systems. The standard covers the spigot (plain-end) series for a defined range of nominal sizes (DN 40, 50, 70, 75, 100, 125, 150, 200, 250, 300, 400, 500 and 600) and includes dimensional tables, coating and marking requirements, and control testing procedures.

Key topics and technical requirements

• Scope and application: Products covered are for gravity discharge pipelines (wastewater, sewage, rainwater and ventilation) and are intended for the listed nominal sizes (DN 40–600).
• Type of ends and jointing: Pipes and fittings are the spigot type (without sockets); joint characteristics and tolerances are to be defined in national standards or manufacturer catalogues. Minimum free end lengths are specified to ensure satisfactory assembly.
• Material quality: Cast iron grade must be at least 150 (per ISO 185) with phosphorus content
