Traceable Results for Shop-Floor Gaging
Gage blocks, ring and plug gauges and surface plates see daily handling that bridge and gantry CMMs do not. Calibration under ISO/IEC 17025:2017 confirms size, flatness or parallelism against NIST-traceable reference standards, with the grade or tolerance class checked against the purchase order before any measurement is taken.
Grade and tolerance class are confirmed against the quotation before testing begins. Gauges found outside their stated class are reported, not silently adjusted, and the as-found condition is recorded on the certificate alongside the reference standard and uncertainty used.
Gage Types Covered
Calibration is matched to the gauge type and class specified on the purchase order or quality procedure.
Gage blocks
Size and flatness verified by grade against a master block set.
Ring and plug gauges
Diameter checked against the stated go/no-go tolerance class.
Granite surface plates
Flatness mapped across the working surface and reported by grade.
Thread and height gauges
Pitch diameter and height standards verified against reference masters.
