Air leakage

  • Product Code: EN-13180-59
Air leakage

The reference test element shall be placed horizontally with two end caps sealed. The test apparatus

comprises an air supply with variable air flow rate, an air flow meter and a pressure gauge meter as

shown in Figure 4. The air flow capacity shall be sufficient to maintain the required pressure levels

specified in Table 5.


The test pressure shall be maintained for five minutes and at the end of this period the leakage flow
rate shall be recorded.
The leakage factor shall be determined by the air leakage rate divided by the surface area π. dn.L where L is the length of the reference test element and dn  is its nominal diameter.
