ISO 15848 standardizes the measurement, testing, and evaluation of industrial valve fugitive emissions. It is divided into two parts:
ISO 15848-1: Defines test procedures for valve type testing.
ISO 15848-2: Specifies requirements for valve product manufacturing.
The German fugitive emission control law TA-LUFT VDI 2440 defines leakage rates, testing, and methods.
TA-LUFT and VDI 2440: Require flange connections to meet a test pressure of 1 bar with a leakage rate less than 10−4 mbar × l/(s × m).
VDI 2200: Specifies selection, calculation, design, installation, and testing of flange connections. It references VDI 2440 for leakage rates and includes burst pressure tests to prevent flange breakage and sudden leakage.
The Clean Air Act mandates that valves, pumps, and agitators in the United States comply with EPA Method 21 (blower method) for leakage testing, with consistent testing methods.
