1.1This guide establishes a classification system and references test methods for verifying the degrees of:

1.1.1The ingress of dust into the internal layers of a membrane switch.

1.1.2Ingress of water into the internal layers of a membrane switch.

1.1.3Where external test methods are referenced, this guide specifies the special conditions that shall be considered in applying these tests to membrane switches and how the results are interpreted.

1.2This guide references test methods that can be used to establish the ingress classification of a membrane switch.

1.3This guide utilizes the test methods and reporting structure of IEC 60529 – (Degrees of Protection Provided by Enclosures) modified for membrane switches.

1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
