ISO/TC 117/WG 7 - Performance testing of fans

This document establishes a uniform method of laboratory testing for the determination of airflow propelled through an open personnel door by a positive pressure ventilator. NOTE The test described by this document is not entirely in accordance with ISO 5801, though it references several subclauses of ISO 5801 (such as the measurement of pressure and airflow). This document does not specify a testing procedure for the design, production or field test of any PPV, nor is it the purpose for this document to serve as a manual for the construction, validation or calibration of the test facility. This document does not apply to any item of equipment designed or intended for applications other than positive pressure ventilation.

ISO 5801:2017 specifies procedures for the determination of the performance of fans of all types except those designed solely for air circulation, e.g. ceiling fans and table fans. Testing of jet fans is described in ISO 13350. ISO 5801:2017 provides estimates of uncertainty of measurement and rules for the conversion, within specified limits, of test results for changes in speed, gas handled and, in the case of model tests, size are given.
