Automatic Nadcap reports

06 March 2007

A software package enabling Yokogawa’s DAQSTATION family of paperless recording systems to produce National Aerospace and Defence Contractors Accreditation Program (Nadcap) survey reports has been developed.

Nadcap is a worldwide co-operative programme of major companies and the survey reports are typically used by the aerospace and automotive industries to assess furnaces used for the heat treatment of metals.

Nadcap’s AMS2750: Pyrometry (Revision D) is the key standard to which heat-treatment suppliers have to conform. This specification covers pyrometric requirements for thermal processing equipment used for heat treatment. It covers temperature sensors, instrumentation, thermal processing equipment, system accuracy tests and temperature uniformity surveys. These are necessary to ensure that parts or raw materials are heat treated in accordance with the applicable specification. In particular, it places tight constraints on temperature control and uniformity of heat-treatment furnaces, and requires comprehensive survey reports as part of its audit process.

DAQSTATION can continuously monitor and store multiple process variables and interfaces with PCs running customised software. Display and archiving facilities are claimed to allow survey reports to be created in the appropriate format to meet the requirements of Nadcap auditors.

The PC-based software produces a report based on a number of files from the DAQSTATION, incorporating test data and an overview of parameters, such as minimum and maximum temperatures over a pre-set period of time. Reports can be customised so users can add their own templates.

David Jones, UK product sales manager for Yokogawa’s network solutions division, said: “Accreditation of production processes is becoming increasingly widespread in a variety of industries, and Yokogawa’s track record in sectors as varied as petrochemical, pharmaceutical and automotive means that we are well placed to provide this sort of support.

“The success of our efforts can be judged by the fact that a Nadcap qualified auditor has seen our report and has indicated that it produces exactly what is required.”
