Причина отмены This guide establishes a classification system and references test methods for verifying the degrees of ingress of dust and water into the internal layers of a membrane switch and the special conditions that shall be considered in applying these tests to membrane switches when external test methods are referenced.

Formerly under the jurisdiction of Committee F01 on Electronics, this guide was withdrawn in November 2023. This standard is being withdrawn without replacement because Committee F01 was disbanded.

Значение и использование

5.1 Ingression protection classifications are widely used by manufacturers for specifying the level of protection offered by enclosures.

5.2 An example of such a classification scheme is IEC 60529. Membrane switch manufacturers are often asked to meet these standards, however the test methods specified within these standards do not address considerations specific to membrane switches.

5.3 The MSIP classification system considers the membrane switch separately from the testing and IP codes used for classifying the enclosure when subject to similar test conditions.

5.4 Ingression testing can be useful to identify design deficiencies.

Область применения

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

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

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

1.1.3 Where 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.

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

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

1.4 This 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.
