BHC recognises that quality is not just a functional part of
the manufacturing process, necessary to maintain order
and control, it is a philosophy that pervades the whole
organisation at every level. Quality is the responsibility
of every member of the BHC team where the emphasis is
placed on “right first time” and “continuous improvement”.
For BHC total quality forms the bond with its customers. It
no longer serves to solely satisfy their current needs but
creates the environment for development and improvement
design, development, production, installation
and servicing”. It is also known as BS EN
ISO9001:2000. Additionally certain
ranges in the motor start capacitors
are approved to VDE 560.
The benefits of the total quality
philosophy and systems that BHC
have adopted are evident in the
service it provides. One of the key
concepts underpinning operations
management is optimum batch size
which strikes the perfect balance between manufacturing
throughput efficiency and traceability. The customer benefits
from this with the availability of the most cost competitive
order quantities and price, combined with maximum
flexibility in tailoring the product to their needs, and
enhanced traceability for individual capacitors.

Customer Return Analysis
One feature of the quality system concerns the investigation
of field failures. Components returned from the field
for technical reasons will be subjected to a rigorous
investigation and, unless otherwise specified, a written
report will be provided. The data collected from this
exercise is collated in a database and reviewed by senior
management resulting in corrective actions where necessary.
Reliability and Failure Rates
The reliability of a component can be defined as the
probability that it will perform satisfactorily under a given
set of conditions for a given length of time. In order to
calculate the reliability for a component the failure rate will
need to be used.
Failure rates for BHC components have been established as
a result of many years of routine endurance testing. Most
of these tests are carried out at rated temperature with full
rated voltage and ripple current applied. Extensive analysis
of this data has enabled failure rates to be established for
most product ranges with a 60% confidence level.
Full details of the reliability and failure rates is included
in a technical article, TD002, in “Aluminium Electrolytic
Capacitors - Application Notes”, available from BHC.
