DIN EN 1672-2
This standard plays a key role for food machinery. It recommends that manufacturers furnish proof of the proper design of their systems and components and also conduct a documented risk analysis. This standard focuses especially on the design of systems, machines and their components. Surfaces must be corrosion-resistant, non-toxic and easy to clean, and the materials or coatings used may neither contaminate the food nor transfer unwanted odors and dyes or flavorings. Gaps, cracks and other dead spaces in which parts of the food or cleaning substances could accumulate are prohibited; connecting elements such as screws or rivets should be avoided or have to be able to be cleaned, and bearings and shaft holes must be located outside of the food area, if possible, and be lubricated with lubricants that are suitable for use with foods.
