scope:

This standard establishes a uniform method of laboratory testing for the determination of airflow propelled through an open personnel door by a positive pressure ventilator. Each test shall be limited to one PPV per test. A PPV tested in accordance with this standard shall be freestanding and without a ductwork connection to the test chamber, thereby allowing for the measurement of entrained airflow. The maximum nominal propeller diameter of a PPV tested in accordance with this standard is 0,80 m.

Note The test described by this standard is not entirely in accordance with ISO 5801, however it references several parts of ISO 5801 which are normative for this standard (such as the measurement of pressure and airflow).

It is not the purpose of this standard to specify a testing procedure for the design, production or field test of any PPV, nor is it the purpose for the standard to serve as a manual for the construction, validation or calibration of the test facility.

Any item of equipment designed or intended for applications other than positive pressure ventilation is not within the scope of this standard.
