Bibliography
Recommended test methods and test conditions to ensure the minimum requirements for stereomicroscopes are defined in this standard. These minimum requirements are given in ISO 10936-1, ISO 11884-1 and ISO 11884-2. The test methods defined in this International Standard are recommended, but use of other test methods is allowed if the same results are obtained.
