    Abstract - (Show below) - (Hide below)

    Defines 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.

    Scope - (Show below) - (Hide below)

    This document 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 ISO13350.

    This document 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.
