“Each gauge shall be capable of indicating forces directly in Newtons or be accompanied by a conversion chart so that the imperial readings can be converted into Newtons”
- Gauges usually indicate pressure, not Force. This allows use of same calibrated set of pump and gauge with different hydraulic jacks (different ram areas) . A conversion chart must be provided
“Each gauge shall be accompanied by a certified calibration curve that bears the seal and signature of an Engineer.”
- Calibration curves must be certified by a third party. Stamping and sealing by an engineer can be logistically challenging/impossible, depending on the specific requirements of laboratories
