Overview

SIST ISO 49:2001/Amd 1:2018 is an important amendment to the original ISO 49:1994 standard, focusing on malleable cast iron fittings threaded to ISO 7-1. This amendment specifically addresses the chemical composition of the zinc coating applied to these fittings. Its core purpose is to adjust the zinc coating requirements to align with contemporary regulations concerning hazardous substances. The standard was developed and published by the International Organization for Standardization (ISO) in 2018.

This update ensures that the zinc coatings used on malleable cast iron fittings conform to safer environmental and health standards by limiting the presence of substances considered hazardous. Consequently, SIST ISO 49:2001/Amd 1:2018 promotes safer manufacturing practices while maintaining product quality and performance.

Key Topics

• Chemical composition of zinc coatings
  The amendment defines maximum permissible mass percentages of trace elements in the zinc coatings to reduce hazardous substances:

  • Aluminium (Al): max 0.10%
  • Antimony (Sb): max 0.01%
  • Arsenic (As): max 0.02%
  • Bismuth (Bi): max 0.01%
  • Cadmium (Cd): max 0.01%
  • Copper (Cu): max 0.10%
  • Lead (Pb): max 0.10%
  • Tin (Sn): max 0.10%

• Harmonization with related ISO standards
  The amendment updates normative references, replacing earlier editions with current ISO standards including:

  • ISO 228-1 for pipe threads dimensions and tolerances
  • ISO 2859 series for sampling procedures and inspection by attributes
  • ISO 5922 for malleable cast iron
  • ISO 6708 for nomimal size definitions of pipework components

• Compliance with hazardous substances regulations
  Ensures zinc coatings meet actual hazardous substance requirements pertinent to safety and environmental protection, minimizing toxic elements.

• Quality and testing procedures
  References standards related to coating thickness measurement (ISO 2178), hot-dip galvanizing evaluation (ISO 1460), and quality management (ISO 9001).

Applications

SIST ISO 49:2001/Amd 1:2018 applies broadly to industries utilizing malleable cast iron fittings with threaded pipe connections, including:

• Plumbing and piping systems
  Ensuring pipe fittings used in water supply, heating, and gas installations meet safety and environmental standards.

• Industrial pipelines
  Facilitates reliable and safe connections in chemical, oil, and gas industries requiring corrosion-resistant components.

• Construction and municipal infrastructure
  Compliance allows fittings to be safely embedded in infrastructure systems while adhering to hazardous substance restrictions.

• Manufacturing and quality assurance
  Enables producers to maintain manufacturing consistency with established limits on toxic substances in protective coatings.

Related Standards

• ISO 7-1 and ISO 7-2 – Specifications and verification for pipe threads where pressure-tight joints are made on threads.
• ISO 228-1 and ISO 228-2 – Dimensions and verification of pipe threads where pressure-tight joints are not made on threads.
• ISO 1460 – Gravimetric determination method for hot dip galvanized coatings on ferrous materials.
• ISO 2178 – Magnetic method for measuring coating thickness on magnetic substrates.
• ISO 2859 series – Sampling procedures for inspection by attributes, relevant to lot-by-lot and skip-lot inspection.
• ISO 5922 – Specifications related to malleable cast iron.
• ISO 6708 – Definitions and selection of nominal pipe sizes.
• ISO 9001 – Quality management system requirements ensuring consistent product quality.
