Food-grade claims versus approval of the finished hose

Short answer

A food-grade material and a finished hose assembly suitable for a food application are not the same thing. The inner tube, seal, fitting, assembly, cleaning and actual service conditions must be evaluated together. The part covered by the document must be clearly matched to the delivered product.

Technical explanation

A food-contact declaration for a material is an input for that material's conditions of use. The assembly contains other materials and geometries. The inner surface of the fitting, seal placement and cleanability are also important for the process. In addition, the regulatory scope of different material types may not be the same. It is therefore not correct to present a document for a hose inner tube as unlimited hygiene and process approval for the entire system.

How is it assessed in practice?

Check the delivery file together with the component list. To which line is the document or conformity basis of each contacting part linked? For example, if a coupling from a different series has been assembled onto a food hose, the scope of the coupling and seal is checked separately. Then the geometry, cleaning and traceability requirements of the finished assembly are evaluated. When displaying a certificate badge on a website, do not combine different claims such as 'material declaration', 'product scope' and 'assembly verification' under a single label. Do not draw a conclusion about assembly suitability before determining whether the document covers only the material or the finished assembly.

Original editorial recommendation; not a clause of a standard.

Frequently asked questions

If all parts are food grade, is the assembly automatically suitable?

The suitability of the parts is an important input; however, assembly geometry, actual service and cleanability are evaluated separately. Component documents do not eliminate these checks.
