Inspection certificatesThe final inspection of JBOpreci sion thread gauges and theissueof inspection certificates conformsto national and internationalstan dards. The slip gauges andinspection equipment used arerecalibrated by recognized institutesat regular intervals. This istestified in detail on the inspectioncertificate. “Our air conditionedinspection department is entirelyindependent from manufacture.Inspection and documentationconform to pages 23 and 24 ofthe guidelines No. 2618 issuedby the VDI (Association of GermanEngineers), the VDE (Associationof German Electrical Engineers)and the DGQ (German Society forQuality Promotion). The inspectioncertificates show the actual pitch(effective) diameter and conform tothe requirements for the checkingof inspection equipment specifiedin EN ISO 9001.Mahr 828 measuring machines andan IAC Master Scanner are used forinspection.Ring gauges for the threadslisted in our catalogue with majordia meters ≥ 2 mm and pitches≥ 0,35 mm are checked by thethree ball method.Both gauge and inspection certificatebear the same serial number.Used gauges that already have aserial number retain that number.If any gauges sent to us for checkingare no longer within the specifiedtolerances and arereplaced by new gauges, no chargeis made for the inspection of thediscarded gauges.Subject to a surcharge, we can alsoextend the inspection to include thethread angle and the pitch, as wellas the major diameter on threadplug gauges and the minordiameter on thread ring gauges.For permanent protection,we supply our thread gauges inindividual transparent packing.Inspection certificate for new thread gaugesInspection certificate for used gauges sent for checkingThread Net unit price for inspection certificate Pris Kr.major dia.
