    Several testing standards are used to evaluate the performance of lift check valves, including those manufactured in China. These standards ensure that the valves meet specified criteria for functionality, safety, and reliability.

    Some commonly used testing standards for lift check valves, including those applicable to products manufactured in China, may include:

    1. GB/T (Guo Biao / 国标): GB standards are Chinese national standards that cover various industries and products. Several GB standards may apply to lift check valves, including:

      • GB/T 13927: Steel valves - Lift check valves.
      • GB/T 9124: General specification for steel pipe check valves.
      • GB/T 12235: Valve pressure test.
    2. API (American Petroleum Institute): While API standards are not specific to Chinese products, they are widely recognized internationally and may be referenced for evaluating lift check valves, especially in applications within the oil and gas industry. Relevant API standards include:

      • API 598: Valve inspection and testing.
      • API 6D: Specification for pipeline valves.
      • API 6FA: Fire test for valves.
      • API 607: Fire test for soft-seated quarter-turn valves.
      • API 6DSS: Subsea pipeline valves.
    3. ISO (International Organization for Standardization): ISO standards are globally recognized and may be referenced for evaluating lift check valves manufactured in China. Relevant ISO standards include:

      • ISO 5208: Industrial valves - Pressure testing of metallic valves.
      • ISO 5752: Metal valves for use in flanged pipe systems - Face-to-face and center-to-face dimensions.
      • ISO 15848: Industrial valves - Measurement, test, and qualification procedures for fugitive emissions.
    4. BS (British Standards): Although originating from the UK, BS standards are often used or referenced internationally. Relevant BS standards for lift check valves may include:

      • BS EN 12266: Industrial valves - Testing of metallic valves.
      • BS 1868: Steel check valves (flanged and butt-welding ends).
      • BS 5153: Specification for copper alloy globe, globe stop and check, check and gate valves.
    5. JIS (Japanese Industrial Standards): While primarily used in Japan, JIS standards may also be referenced for evaluating lift check valves, especially in East Asian markets. China lift check valve  Relevant JIS standards include:

      • JIS B 2062: Steel valves - Flanged and butt-welding ends.
      • JIS B 2071: Steel globe valves.
      • JIS B 2074: Steel globe stop and check valves.

    These are just a few examples of the testing standards that may be used to evaluate the performance of lift check valves, including those manufactured in China. The specific standards applicable to a particular product will depend on factors such as industry requirements, application specifications, and regulatory compliance. It's essential for manufacturers and users to ensure that the valves meet relevant standards to ensure safety, reliability, and compliance with industry requirements.
