Force DUROMETER-218

Durometer

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of two standard durometers. This ILC/PT Kit contains two standard durometers.

Participants will use their lab practices to perform 16 displacement measurements ranging from 0.020 in to 0.080 in with forces from 40 gf to 4533 gf. Test methods and test reporting are based on ASTM D2240 industry requirements. Measurement values will be appropriate for calibration of similar devices. 

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Force FORCE-203

1,000 lb Load Cell (Compression only)

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to measuring the mV/V output of a force transducer.

Participants will use their lab practices to perform 8 Load Cell force measurements from 100 lbf to 1000 lbf, and Load Cell Input and Output Resistance. The expected uncertainty of this 3 mV/V transducer is largely dependent on the calibration process and equipment used and will vary from 20 µV to 500 µV. 

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Force FORCE-301

1,000 lb Load Cell With Indicator

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibrating a small capacity load cell using a digital indicator.

It will read directly in engineering units over the range of 100 to 1000 lbf. The associated uncertainty is expected in pounds and varies with set point and setup method over this range. This ILC/PT Kit contains a 1000 lb Load Cell with Digital Indicator.

Participants will use their lab practices to perform 6 measurements of force. Measurement values will be appropriate for calibration of similar devices. 

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Force FORCE-313

100 lbf Digital Force Gauge

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of a small capacity force measurement instrument utilizing dead weights. 

Participants will use their lab practices to perform 5 measurements of tension and 5 measurements of compression between 10 and 100 lbf. Measurement values will be appropriate for calibration of similar devices.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.
