Common Certifications The following standard certifications are available from Watlow. Requirements for the following standard certifications available from Watlow must be stated on an order. Certificates #1, 2, 3 and 4 are only available as a “Certificate Package” comprised of all four certificates. Certificate #1 - Certificate of Compliance/Conformity This certification states that the product supplied meets the purchase order requirements. Certificate #2 - Certificate of Compliance to ASTM E230 Tolerance This certification states that the product being supplied meets the purchase order requirements, including the correct calibration type and tolerance. This certification is also used when conformance to ASTM E230 must be documented. Certificate #3 - Certificate of Conformance to ISO 10012 This certificate certifies that Watlow’s calibration system is in accordance with ISO 10012. Certificate #4 - Certificate of Traceability to National Institute of Standards and Technology (NIST) This certification certifies that the materials received are traceable to NIST via calibration data of the thermoelements used to manufacture the product. for an extra charge. Each thermocouple, coil, reel or spool of wire is tagged to show the individual departure from curve. Once calibrated, exact departure from the standard curve at any specified temperature is known and considered. Thermocouples and wire samples sent to the factory for calibrating must be at least 36 inches in length. Calibrating temperature points range from 32 to 2300°F (0 to 1260°C), depending on calibration, gauge size and insulation. Sub-zero and cryogenic calibration is available at temperatures down to -100°F (-74°C). A certificate of calibration and a calibration results tag are furnished for all items calibrated. Calibration and Certification SERV-RITE ® thermocouple wire, XACTPAK metal sheathed cable and individual temperature sensors can be calibrated and certified in Watlow’s calibration laboratory

Certificate #5 - Certificate of Calibration for Bulk XACTPAK This calibration certificate provides overall lot calibration data for the bulk XACTPAK. The data will indicate how the final sensor will perform without the additional cost to calibrate each individual sensor. Certificate #6 - Certificate of Calibration for Bulk SERV-RITE Insulated Wire This calibration certification provides preproduction calibration values of the insulated wire product at standard calibration check points. Certificate #7 - Chemical Composition of Conductors Used in Insulated Wire Products Watlow tubing and insulator vendors supply certification on the chemical composition and physical characteristics of their products (material certification) with each lot received. When requested, certifications are duplicated (proprietary information is blocked out) and sent to customers. Certificate #7A - Chemical Composition of Conductors Used in Insulated Wire Products This certification offers nominal chemical composition of the alloy used in insulated wire products. Certificate #8 - Certificate of Calibration at Specified Temperatures This calibration certification provides post-production calibration data. Calibration is performed in the Watlow calibration laboratory with NIST traceable calibration standards. In addition to calibration data, the test standard, equipment, NIST traceability and reference to applicable calibration procedures are stated.
