ISO 9237 Air Permeability

Standard:

ISO

Method:

ISO 9237

Title:

Determination of the permeability of fabrics to air

Scope

ISO 9237 Air Permeability describes a method for measuring the permeability of fabrics to air and is applicable to most types of fabrics, including industrial fabrics for technical purposes, nonwovens and made-up textile articles that are permeable to air.

Principle

The rate of flow of air passing perpendicularly through a given area of fabric is measured at a given pressure difference across the fabric test area over a given time period.

Samples

IPS uses a 100 Pa pressure differential for apparel fabrics and a 200 Pa pressure differential for industrial fabrics unless a different pressure differential is specified by the customer. IPS conditions and tests at 50% RH and 23°C.
