Ingress protection (IP) ratings show the level at which a product is protected from the environment e.g. whether outdoor equipment is adequately protected from adverse weather conditions, or if it is suitable to
be submersed or pressure cleaned.
The level of protection is signified by a recognised IP code, e.g. IP68 where the first digit  indicates the ingress protection against solid bodies such as dust; and the second digit  indicates the level of protection against liquids.
Ingress protection tests are conducted in accordance with IEC 60529 (or other equivalent national standards) and ensure that the cable gland is effective at sealing against the cable, therefore preventing dust or liquid entering the equipment enclosure.
ON-SITE TEST FACILITIES
CMP Products houses an on-site test facility, including a wide range of ingress testing conditions, to ensure that all cable glands are fully tested before they are subjected to 3rd party certification. This investment in research & development means that products can be rigorously tested beyond the normal limits; leading to the design of products that are capable of outperforming even the safest of international standards.
PRODUCTS APPROVED TO IP66, 67, 68, 69, 69K
All products within the TruSeal range are tested to IP66, IP67, IP68, IP69 and IP69K (as defined in the tables opposite). To ensure that these ratings are achieved, CMP products provides O-ring interface seals for metallic products and entry thread polymer sealing washers for the polymer cable
glands as standard. These features ensure that the required environmental protection will be achieved irrespective of the enclosure material or surface
IP68 TESTED FOR 16 HOURS AT 300 kPa
The TruSeal range has endured the most onerous of tests, including a 300 kPa (3 bar) 16-hour pressure test, achieving an IP68 rating equivalent to 30
metres’ depth of water. Often competitors will test their products to a lower pressure or a shorter exposure time making the test easier test to pass.
CMP can also conduct bespoke, customer-specific ingress protection tests for alternative depths and durations upon request. Ideally IP68 testing should be carried out using a specified cable, depth and time agreed with the customer.
TRANSIT DISCS AND IP PLUGS
CMP TruSeal transit discs are used as a means of protecting equipment and enclosures from dust and moisture in all CMP TruSeal cable glands whilst in transit. Transit discs provide a resilient, weatherproof, temporary seal and should be removed before equipment is commissioned.
CMP TruSeal Ingress Protection (IP) Plugs are used as a means of protecting equipment and enclosures from dust and moisture. These IP plugs are for use in explosive atmospheres or industrial environments and are rated IP66 – IP69K, equaling the ingress protection rating of the host TruSeal cable gland.
These sealing plugs provide enhanced protection, forming a resilient temporary or permanent seal. They are certified to equal the rating of the CMP TruSeal cable gland they are installed with; for example a plug used with a TSPe will be certified for Ex e and Ex ta equipment.
