Reliability and Approvals

Isocom Ltd supplies high reliability devices for applications requiring an operating temperature range of -55°C to +125°C (e.g. military applications).
Devices supplied have completed rigorous testing, and various high reliability test options are offered. The Company is developing a suitable specification to permit release to CECC 20000.
As a manufacturer of high reliability optocouplers Isocom Ltd's manufacturing plant in North East England, has site approval to BS9000 (registered number 1294/M) issued by the British Standards Institution. Together with CECC, BS9000 is a preferred standard for use in European military projects. Consequently, Isocom Ltd's approved devices are listed in the CECC "MUAHAG" preferred products list.
The BS9000 approval is also recognised as meeting the equivalent criteria to those required by BS5750/ISO9000/EN29000.
The Company's customers can be assured of our commitment to stringent quality, reliability and inspection standards, as demonstrated by our existing approvals. Other customer-specific options can also be offered.
