The National Aerospace and Defense Contractors Accreditation Program (Nadcap) has clear and stringent guidelines for accreditation. One area that often causes accreditation problems is the incorrect handling, formatting and storage of data. The good news is that Nadcap offers a clear list of requirements, and by installing the right equipment and following some basic steps, meeting these data demands is simple.
The Right Start
The most important thing you can do for data integrity is to work with a good partner that understands data formatting and Nadcap requirements. They’ll provide the right controllers, software and other systems to capture all necessary data, and they’ll make it easy to record and access it.
Don’t settle for a vendor who is just selling a product and connecting it. Look for someone who will work with you to understand your needs and engineer a system that makes Nadcap compliance a priority.
We strongly recommend SpecView software for all your supervisory control and data acquisition (SCADA) needs. Modern equipment, combined and integrated with SpecView software, will automatically record, store and back up data, and that’s a large element of meeting Nadcap requirements.
When it comes to data, Nadcap leans heavily on AMS2750 pyrometry standards, which have these basic guidelines:
- 3.2.7 Electronic Records
- 184.108.40.206 An “electronic record” is any combination of text, graphics, data, audio, pictorial, or other information representation in digital form that is created, modified, maintained, archived, retrieved, or distributed by a computer system. When using a system (furnace control, recording, monitoring or data acquisition) that creates electronic records, systems purchased after Sept 2006 or any electronic record created after 2015 (3 years after the release of this revision) shall meet the following requirements:
- 220.127.116.11.1 The system must create electronic records that cannot be altered without detection.
- 18.104.22.168.2 The system software and playback utilities shall provide a means of examining and/or compiling the record data, but shall not provide any means for altering the source data.
- 22.214.171.124.3 The system shall provide the ability to generate accurate and complete copies of records in both human readable and electronic form suitable for inspection, review, and copying.
- 126.96.36.199.3.1 The system shall be capable of providing evidence the record was reviewed – such as by recording an electronic review or a method of printing the record for a physical marking indicating review.
- 188.8.131.52.4 The system shall support protection, retention and retrieval of accurate records throughout the record retention period. Ensure that the hardware and/or software shall operate throughout the retention period as specified in 3.7.
- 184.108.40.206.5 The system shall provide methods (e.g., passwords) to limit system access to only individuals whose authorization is documented.
One additional requirement from Nadcap is from its pyrometry checklist, which stipulates that software updates and new programs installed on a system require that a cycle is run with no production materials. You can use test samples or run the system empty. A best practice when running any cycle in a furnace is to keep a sequential log that includes a chart—including test cycles—and retain those records like you would for any other production cycle. This allows you to easily demonstrate that you followed the guidelines with the required test run.
