aPI 607 vs ISO 10497 valve
API 607 applies to verifying the pressure resistance of quarter-turn valves (whether with non-metallic or metallic seats) and other valves equipped with non-metallic seats during and after fire testing. The standard explicitly excludes testing requirements for valve actuators other than manual gearboxes or similar mechanisms.
ISO 10497 specifies the requirements and methods for fire resistance testing of valves to verify their pressure resistance during and after fire testing. This international standard does not include fire resistance testing requirements for actuators other than manual gearboxes or other similar mechanical components derived from valve assembly. Other types of valve actuators (e.g., electric, pneumatic, or hydraulic) require special protection to ensure the valve can operate under set conditions during testing; fire resistance testing of such actuators is not within the scope of this standard.
| Dimension | API 607 | ISO 10497 |
|---|---|---|
| Standard Type | Industry-specific (Oil & Gas/Chemical) | International General Standard |
| Valve Coverage | Soft-seated ball, plug, butterfly valves | All industrial valves (gate, globe, etc.) |
| Fire Test Duration | Fixed 30 minutes | 15 or 30 minutes (declared in advance) |
| Operational Test | Mandatory post-fire cycling under pressure | Optional (typically excluded) |
| Leakage Criteria | Internal/External leak ≤100 mL/min | External leak ≤100 mL/min (looser internal req.) |
| Primary Use Cases | Oil platforms, refineries, high-risk zones | Power, marine, general global projects |
