When selecting galvanised malleable iron pipe fittings for industrial, plumbing, or fire-protection systems, compliance with international standards is essential. These standards ensure that every fitting delivers reliable performance, pressure resistance, and long-term safety. As a professional manufacturer, Jizhong follows a complete certification system covering ASTM, ASME, FM, UL, and regional requirements to support global project needs.

ASTM & ASME Standards – The Core Requirements

For galvanised malleable iron pipe fittings, ASTM A197 and ASME B16.3 are the two foundational standards.

ASTM A197 – Material & Casting Requirements

This standard defines the chemical composition, production methods, and mechanical properties required for malleable iron castings.

ASME B16.3 – Dimensions & Pressure Ratings

ASME B16.3 specifies the dimensional tolerances, threading rules, and pressure ratings (Class 150) for malleable iron fittings.

Together, these two standards ensure that Jizhong galvanised malleable iron pipe fittings:

  • Meet Class 150 pressure requirements
  • Maintain structural integrity under varied operating conditions
  • Provide consistent mechanical strength and performance

FM & UL Certifications – Essential for Fire Protection

For fire-fighting and sprinkler systems, FM (Factory Mutual) and UL (Underwriters Laboratories) certifications are mandatory.

CERTIFICATE OF COMPLIANCE

These approvals confirm that Jizhong galvanised malleable iron pipe fittings:

  • Meet strict fire-protection performance standards
  • Undergo rigorous testing for pressure, leakage, and durability
  • Are approved for use in fire sprinkler systems and fire-protection networks

If your project involves fire safety, FM/UL-approved fittings are non-negotiable.

Regional Certification Requirements

Different regions also require specific approvals to meet local regulations.
Jizhong fittings support multiple international markets with certifications including:

  • ABNT — for Brazilian construction and industrial projects
  • CE — for European Union compliance
  • TSE — required for projects in Turkey

With these certifications, Jizhong galvanised malleable iron pipe fittings ensure smooth project acceptance worldwide.

ISO Quality Management Certification

Jizhong operates under ISO 9001 quality management standards, covering:

  • Stable production processes
  • Consistent batch-to-batch quality
  • Full traceability and documentation
  • Strict quality control and testing procedures
