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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

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.
