Hydrostatic Testing Equipment – ISO 6792 Compliance

Iran National Standard 6792 defines the procedures, technical requirements, and acceptance criteria for performing periodic hydrostatic testing of gas cylinders. This standard ensures the safety, integrity, and reliability of cylinders used in medical, industrial, and laboratory applications.

Purpose and Scope

  • Primary Application: Periodic testing of steel, aluminum, and composite gas cylinders.
  • Intended Users: Cylinder testing centers, cylinder manufacturers, gas distribution companies, and regulatory authorities.

Key Provisions of Standard 6792

  1. Hydrostatic Test Conditions
    • Test Pressure: Typically 1.5 × the cylinder’s Working Pressure (WP).
    • Holding Time: Minimum of 30 seconds, depending on cylinder type.
    • Test Medium: Water or other temperature-controlled compatible fluid.
  2. Acceptance / Rejection Criteria
    • Permanent Expansion: Must not exceed the specified allowable limit.
    • Leak Detection: No visible leaks or surface cracks permitted.
    • Deformation: No unacceptable distortion of the cylinder body.
  3. Required Equipment
    • Hydrostatic Testing Machine capable of precise pressure application and volumetric expansion measurement.
    • Safety Systems to prevent accidents or explosions.
    • Calibrated Measuring Instruments for accurate results.
  4. Documentation
    • Record applied pressure, permanent volume change, and cylinder’s visual condition.
    • Affix a tag or marking on tested cylinders for traceability.
