Ingress Protection Testing

As part of our accredited testing scope CML can offer either as part of a certification project or stand -alone testing Ingress Protection (IP) testing against IEC 60529.

IP testing determines the level of protection equipment has against solids and liquids. By testing against the standard we measure the effect of the exposure has on the equipment and give the appropriate IP rating.

Pre-Compliance Testing

As part of our technical support service CML’s customers can take advantage of our pre-compliance testing service. This allow manufacturers of EX equipment to use our facility to test, against relevant standards the suitability of their product for passing the testing requirement or achieving product certification. We can advise on testing requirement of the standards, sample requirements and supply results of the tests. The results of the testing can be used in support of full applications for EX product approval.
