7 Test Procedure
7.1 Test Environment Criteria
To facilitate testing and to maximize the quality and accuracy of the test results,
adhere to the following instructions:
1. Select a dust-free test environment.
2. Verify that the test equipment is isolated from vibrations.
3. Verify that there is sufficient space around the instrument for ventilation
and movement of the mechanical parts such as the lid opening etc.
4. Confirm that relative humidity is less than 90 % and non-condensing.
5. Confirm that ambient temperature is within the acceptable range as
specified in the technical specification.
7.2 Sample Selection and Handling
To maximize the quality and accuracy of the test results adhere to the following
recommendations:
1. Select the liquid test sample so as to represent the liquid’s source.
2. Ensure that ambient conditions during testing are similar to those of
liquid’s source.
3. Handle the sample with care so as to avoid moisture and dirt contamination.
4. Store and house the sample in a clean, dry, non-permeable and
sealable container.
5. Shield the container from light sources prior to testing.
Dark or amber glass bottles are recommended.
6. Adhere to recognized standards such as ASTM D923 or IEC 60475:2011
that outline the guidelines for oil sampling procedures.
Impact of the Dielectric Properties
Avoid using plastic containers. Plastic is permeable and can impact
the dielectric properties of the liquid test sample
