Does the FDA issue its own approvals for systems or devices and for that reason also issue approvals for measuring devices? Learn more in the following blog post. There are always uncertainties with this topic, which is 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 tabs on foodstuffs and pharmaceuticals and serves to protect public health in america.
When should FDA requirements be considered?
The FDA?s control 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 completed relative to general GMP requirements (?good manufacturing practice?). These must already be studied 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 case of a failure should be FDA-compliant. These can, for example, 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 sure that the connections are ideal for sanitary applications. Instruments with 3-A marking have been shown to meet up with the specifications for radii and surface roughness (Ra < 0.8 ?m).
Metallic parts which are in contact with the media must have a 3.1 material test certificate relative to DIN EN 10204. In sterile engineering, it really is preferable to 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, since it has improved corrosion properties in comparison to 1.4404 as a result of lower delta ferrite content).
Succeed 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, so long as you take the aforementioned points into account.
