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.
As manufacturer of high
reliability optocouplers Isocom Ltd's manufacturing plant at North East England,
has site approval to BS9000 (registered number 1294/M) and CECC20000 (registered
number M/1084/CECC/UK) 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.
