2.1.3. Terms and Definitions

<sup>1</sup> Door Assembly

A combination of fixed structures (such as doorframes), doors, and attached hardware accessories.

<sup>2</sup> Ambient Temperature

The ambient temperature of this test method is (25 ± 15) ◦C.

<sup>3</sup> Leakage

The volume of air through the door assembly under a pressure difference.

2.1.4. Leakage Regulations

The volume leakage under a pressure difference of 10 and 25 Pa should be measured separately, with the benchmark of 25 Pa pressure difference, which is converted to the volume leakage under standard conditions that should not be greater than 25 m3/h. In addition, the volume leakage under a pressure difference of 10 Pa should be free of abnormalities.
