Rubber- or plastics-coated fabrics -- Determination of resistance to penetration by water

ISO 1420:2016 specifies two methods for the determination of the resistance of rubber- or plastics-coated fabrics to water penetration (hydrostatic resistance) when subjected to a specific hydrostatic pressure over a fixed period of time. Method A specifies the procedure for a low and high hydrostatic pressure and Method B for a low hydrostatic pressure.

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

Introduction

The resistance to penetration by water is often used as a measure of the water-proofing of rubber-

or plastics-coated fabrics when a product made from the coated fabric is exposed to various service

conditions in the field. There are some environmental factors that affect the resistance to water

penetration such as temperature, pressure or chemicals in water, however, the methods in this

International Standard only measure the property at a low to high hydrostatic pressure level at ambient

temperature.
