The scale should only be verified or calibrated when the oven

scale complies with the following standards:

Used in the Testing of Materials
♦
ASTM D 4753, Standard Specification for Evaluating,
Selecting, and Specifying Balances and Scales for use in Soil,
Rock, and Construction Materials Testing
.
Please refer to these standards when identifying the accuracy and
linearity requirements. Troxler recommends calibrating the scale
should it fail the
Verify test.
