Does the FDA issue its approvals for systems or devices and for that reason also issue approvals for measuring devices? Find out more in the following blog post. You can find always uncertainties with this topic, which is why I?d like to shed more light on the question in this blog post.
What’s the FDA?
The FDA (?Food and Drug Administration?) is a US authority under the Department of Health. It is responsible for the tabs on foodstuffs and pharmaceuticals and serves to safeguard public health in the United States.
When should FDA requirements be considered?
The FDA?s control includes both US-made and imported products. Because of this, regular audits are completed at overseas pharmaceutical manufacturers. ราคาเกจวัดแรงดันลม -approved drugs may only be made by FDA-inspected manufacturers whose facilities adhere to FDA regulations.
How are plants and equipment assessed for FDA requirements?
The FDA will not grant approval for measuring instruments. The assessment is carried out in accordance with general GMP requirements (?good manufacturing practice?). These must already be taken into account in the planning of the plant as must the selection of suitable measuring instruments:
Liquids that could find their way into the end product in the event of a failure should 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 must be available.
Process connections should ideally have 3-A approval to make sure that the connections are suitable for sanitary applications. Instruments with 3-A marking have already been shown to meet the specifications for radii and surface roughness (Ra < 0.8 ?m).
Metallic parts which come in connection with the media should have a 3.1 material test certificate in accordance with 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 as the standard material for applications in sanitary applications, since it has improved corrosion properties compared to 1.4404 because of the 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 form of the success of your FDA audit, if you take the aforementioned points into account.
