Application: The load cells may be used in multiple cell applications Class III and IIIL consistent with the model designations,
number of scale divisions, and parameters specified in this certificate. Load cells of a given accuracy class may be used in
applications with lower accuracy class requirements provided the number of scale divisions, the v
suitable for the application. The manufacturer may market the load cell with fewer divisions (n
those listed on the certificate. However, the load cells must be marked with the appropriate n

Identification: A lasered identification label located on the cell, states manufacturer name, model, serial number, v
capacity. Other pertinent information will be specified on the Calibration Certificate accompanying the cell.
Test Conditions: A 125 kg and a 1000 kg capacity load cell were tested by the NMi Certain B.V. at The Netherlands facility. Testing
was conducted in accordance with the OIML DoMC Mutual Acceptance Arrangement, signed by the NCWM as a utilizing participant
for load cell testing. Testing was conducted using deadweights as the reference standard. The load cells were tested over a temperature
range of -10
o
C to 40
o
C with tests run on each cell at each temperature. The temperature effect on zero was measured and a time
dependence (creep) test was performed. The barometric pressure test to determine sensitivity of the load cell design to changes in
barometric pressure was conducted. The data were analyzed for multiple load cell applications. OIML R60 selection criteria were
used to determine cells tested.

Type Evaluation Criteria Used: NIST, Handbook 44: Specifications, Tolerances and Other Technical Requirements for Weighing
and Measuring Devices, 2017. NCWM, Publication 14: Weighing Devices, 2017.
Conclusion: The results of the evaluation and information provided by the manufacturer indicate the device complies with applicable
requirements.
