CERTIFICATE OF TRACEABILITY

We certify that Load Cell Indicator #1000 (serial #00000) and Load Cells (serial #00000) have been tested and calibrated against a reference gauge traceable to the National Institute of Standards and Technology.

The reference gauge was calculated using Ashcroft dead weight equipment certified to be accurate to within 1/10th of one percent.

The weights were calibrated on a balance scale against reference weight whose accuracy is traceable to N.I.S.T. test 38126.  Weight values are based on standard gravity (G=980.665 CM/SEC.SQ)

Piston diameter and cylinder bore were measured for dimensional accuracy by the use of gauges inspected periodically against masters trace ability to N.I.S.T.   test #232.09/204651.

Tester Model:   Ashcroft 1305B100

CERTIFICATE NO.  00000
