Documentation required for instrument acceptance
Thread Content
When starting a new project, as an instrumentation technician, what kinds of certificates and documents are generally required from the manufacturer during the acceptance inspection of the instrumentation upon its arrival?
Certificates, user manuals, and other relevant documents. Imported equipment requires relevant supporting documents such as customs declarations. During the inspection, you need to compare the signed technical agreement with the equipment on site item by item, checking parameters, materials, and other details.
How is the quality of materials generally inspected?
Material inspection requires specialized equipment; it’s not possible to determine this just by looking. On-site inspection mainly focuses on the appearance and model.
If it is an explosion-proof instrument, an explosion-proof certification for the instrument is required, along with the accompanying documents of the instrument itself, etc
Is it necessary for the manufacturer to provide proof of the material, etc.? Are there also valves, and are certificates such as pressure testing and leakage testing for valves required?

Please refer to the Automation Instrumentation Acceptance Specifications
Back then, Sanlu was a **product that did not require inspection, yet it still caused harm without any doubt. There’s no proof whatsoever – absolutely no evidence at all. Test the instrument by yourself – its advantages and disadvantages will be clear at a glance, which is better than any proof. . .
The test materials should be random samples, and the valve leakage tests should be conducted before the product leaves the factory; if a pass certificate is required for these tests, it may incur additional costs.
