Storing and Handling
of the Standards
The use of damaged or dirty standards may severely affect the accuracy of
measurements. Make sure the standards are clean and free from scratches.
Do not touch the surface of the standards and keep them protected when not in use.
Do not store the standards in dirty or dusty environment and do not expose it to direct
sunlight.
Protect the standards against chemicals and aggressive vapors.
Cleaning
Standard surfaces are very delicate, be very carefully when cleaning them.
Use a fresh, soft cloth, and wash the standards in running or standing cold water.
Do not apply a scrubbing action or heavy pressure. Make sure no large particles that
might damage the surface adhere to the cloth.
Do not use aggressive cleaners like solvents, rubbing alcohol, trichloroethylene,
benzine, or strong alcohol, acids or lyes. Most chemical cleaners or polishes will
cause damage!
To remove stubborn dirt, add a little household dish detergent to the water. Rinse
with distilled water. Dry with compressed air and blow off any dust or lint.
Never rub the standards dry! The rubbing action
may cause scratches from surface dust.
Validity
Even when handling the standards carefully, it is possible that the values are
changing within the course of time because of environmental influences. For this
reason, you should have them checked against primary standards in regular intervals
by BYK-Gardner service staff.
The test of validity is recommended once a year.
