IP rating – IP69K

T240 Joint Closure – IP69K approved

Useful information about IP
(International Protection)

IP ratings: IP is an enclosure rating that tells you how good an encapsulation is and how well it resists and protects against dust and water ingress. The letters IP (International Protection) are followed by two digits describing the equipment protection level. The first digit of the IP code indicates the degree to which a person is protected against contact with moving parts (other than smooth rotating shafts, etc.) and the degree to which the equipment is protected against solid foreign bodies intruding into an enclosure. The second digit indicates the degree of protection for the equipment inside the enclosure against the harmful entry of various forms of moisture (e.g. drips, spray, submersion, etc.)

Test procedure

  • Protected against close-range high pressure, high temperature spraying
  • Test duration: 30 seconds from 7 angles (3 minutes total)
  • Pressure: 10 MPa (100 bar)
  • At a distance of 0.125 m
  • Water temperature: 80 °C

Closure´s tested with all variants of bushing technology for the Telecombox T240 system.

Classification of the degree of protection provided by the enclosure

Standard

EN 60529:1991 + A1:2000 + A2:2013
IEC 60529:1989 + A1:1999 + A2:2013
ISO 20653:2013

IP-class

IP68 (2.0 bar/24 h)/IP69, IP69K

Technical description

  • The largest dimension of the Telecombox T240 exceeds 250 mm and the test was therefore performed with the test parameters for large enclosures.
  • The test objects were exposed to high-pressure water from all directions for a total of 3 minutes.
  • The water pressure was approximately 100 bar and the spraying distance was 125 mm.
  • The temperature of the water was 80º C.

Tykoflex testing

At Tykoflex we of course conduct our own tests both outdoors and in our climate chamber, here is an example.
