42、ials The requirements contained in this section are intended to protect food from contamination and ensure that the materials used in the manufacture of equipment resist wear, penetration by vermin, and the effects of foods, cleaning compounds, sanitizers, and other substances that may contact the m

43、aterials in the intended use environment. Materials used in unexposed non-food zone areas shall be exempt from all requirements in 4. 4.1 Conformance with NSF/ANSI 51 Materials shall conform to the requirements in NSF/ANSI 51 applicable to the zone in which the material is used. 4.2 Solder Solder co

44、ntaining lead as an intentional ingredient shall not be used in a food or splash zone. 4.3 Gaskets Gaskets shall be made of resilient rubber, rubber-like materials, or plastics. Gaskets shall conform to NSF/ANSI 51 and shall function at any temperature to which they are exposed in normal operation.

45、5 Design and construction This section contains design and construction requirements for equipment covered within the scope of this Standard. 5.1 General sanitation 5.1.1 Equipment shall be designed and manufactured to prevent the harborage of vermin and the accumulation of dirt and debris, and to p

46、ermit the inspection, maintenance, servicing, and cleaning of the equipment and its components. 5.1.2 Equipment shall be designed and manufactured so that food may be added, processed, finished, dispensed, removed, and/or served in a sanitary manner. 5.1.3 Food zones shall be readily accessible and

47、easily cleanable or shall be designed for in-place cleaning when a readily accessible design is not feasible. NOTE In heavy duty or high speed equipment that requires close tolerances on assembled parts and secure fastening for safety or continuing function, simple tools may be used for disassembly.
