Does the FDA issue its own approvals for systems or devices and therefore also issue approvals for measuring devices? Learn more in the following post. There are always uncertainties with this topic, which explains why I?d like to shed more light on the question in this website post.
What is the FDA?
The FDA (?Food and Drug Administration?) is really a US authority under the Department of Health. It really is responsible for the monitoring of foodstuffs and pharmaceuticals and serves to safeguard public health in the United States.
When should FDA requirements be considered?
The FDA? Pathetic includes both US-made and imported products. For this reason, regular audits are carried out at overseas pharmaceutical manufacturers. US-approved drugs may only be produced by FDA-inspected manufacturers whose facilities comply with FDA regulations.
How are plants and equipment assessed for FDA requirements?
The FDA does not grant approval for measuring instruments. The assessment is carried out relative to general GMP requirements (?good manufacturing practice?). These must already be taken into account in the planning of the plant as must also the selection of suitable measuring instruments:
Liquids which could find their way in to the end product in the event of a failure must be FDA-compliant. These can, for instance, be transmission fluids or fill fluids.
Seals that are in contact with the measuring medium should be manufactured from FDA-compliant material. As proof, a material certificate for the seal should be available.
Process connections should ideally have 3-A approval to make certain the connections are ideal for sanitary applications. Instruments with 3-A marking have been shown to meet the specifications for radii and surface roughness (Ra < 0.8 ?m).
Metallic parts which are in contact with the media should have a 3.1 material test certificate relative to DIN EN 10204. In sterile engineering, it is better use CrNiMo steels, of quality 1.4404 and 1.4435 or 316L. (For instance, WIKA uses 1.4435 because the standard material for applications in sanitary applications, because it has improved corrosion properties compared to 1.4404 as a result of lower delta ferrite content).
The measuring instrument must be calibratable and the accuracy ought to be confirmed by 3.1 or DAkkS certificate.
Conclusion
Nothing will stand in the way of the success of one’s FDA audit, if you take the aforementioned points into account.
