and ANSI/NCSL Z540.3, Requirements fi.r (lie calibration of Measuring and Test Equijnnent. Instruments shall be calibrated on a regular schedule or whenever repairs or modifications are made to them.
For joints in which the overheating of the base metals could adversely affect the properties of the base metal, sensors that shut down the system shall be used if overheating occurs and shall be calibrated as above. Each sensor shall be set at a temperature below the temperature at which the reduction in properties can take place. It shall be located and aligned so that it reads the area of highest temperature. Automatic systems used to manufacture Class A and Class B joints shall be equipped with calibrated control devices that produce a repeatable brazing cycle.
22.214.171.124 To prevent interaction between the induction field and thermocouple-type temperature sensors, noncontact temperature sensing devices may be used to monitor temperature. If used, these devices should be used with caution as they are greatly influenced by the condition of the surface being measured. Flux, oxidation, and material ernissivity will affect the infrared signature of the material.
5.2.5 Atmosphere Induction Brazing Equipment. If induction brazing is to he conducted in a protective atmosphere (including vacuum), the equipment and enclosures shall he in good working condition and shall he as specified in the qualified brazing procedure specification (see 5.4 and 5.5).
126.96.36.199 Electronic Dew Point Measuring Devices. Electronic dew point measuring devices, when used, shall be calibrated in accordance with the manufacturer’s recommendations against reference devices traceable to the National Institute of Standards and Technology (NIST), or equivalent. Such gauges shall be calibrated in accordance with NCSL Z540.3 before initial use and recalibrated at a frequency not to exceed six months.
188.8.131.52 Vacuum Measuring Devices. When used, thermocouple gauges shall be used to measure pressure higher than 0.13 Pa [10—3 torn. Suitable electronic gauges shall he used to measure pressures of 0.13 Pa [10—3 torn or less. These gauges shall he so mounted as to measure the pressure within the work zone of the chamber. Suitable instruments for reading and recording the pressure within the chamber work zone shall also he provided.
These instruments and gauges shall be calibrated in accordance with the manufacturer’s recommendations against reference standards traceable to NIST. Such gauges shall be calibrated in accordance with NCSL Z540.3 before initial use and recalibrated at a frequency not to exceed six months.AWS C3.5M/C3.5:2016 pdf free download.
