ISO 10306:2014规定了通过在两种规定条件下测量棉纤维塞的气流阻力来评估松散随机棉纤维成熟度的方法。该方法适用于从棉花捆中随机抽取的棉花。可以对棉絮、棉条或其他来源的棉絮进行测试，但如果纤维取自成捆，结果可能会有所不同。

ISO 10306:2014 specifies a method for the evaluation of the maturity of loose randomized cotton fibres by measuring the resistance to air flow of a plug of cotton fibres under two prescribed conditions. The method is applicable to cotton taken at random from bales. Laps and slivers or other sources of lint cotton may be tested, however results may differ if fibres are taken from bales.
