An ISO manufacturer is one that subscribes and adheres to an international
agreement of set standards.

Under ISO 9000 the standards dictate the manufacturing process. This does
not mean it is of high quality, but it is going to be consistent in quality.
There are about 20 criteria addressed by the standards including design
control, purchasing procedures, specifications, process control, inspection,
handling, storage, job training, etc.

One company may set a tolerance on a machined part of .0001, another company
making a competitive part may set tolerance at .05. If proper procedure
is followed, you can be assured that what you buy will be in the
specifications, be that good or bad.
