39、nstruction 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 permit the inspection, maintenance, servicing, and cleaning of

40、 the equipment and its components. 5.1.2 Equipment shall be designed and manufactured so that water intended for ice production may be added, processed, and/or finished, so that ice may be dispensed, removed, and/or served in a sanitary manner. 5.1.3 Food zones shall be readily accessible and easily

41、 cleanable or shall be designed for in-place cleaning. Units may be located behind removable access panels, since daily cleaning is not required. 5.1.4 Food zones for which in-place cleaning is intended shall be designed and manufactured so that cleaning and sanitizing solutions may be circulated or

42、 passed throughout the fixed system. The design shall ensure that cleaning and sanitizing solutions contact all food contact surfaces. The system shall be self-draining or capable of being completely evacuated. Equipment and appurtenances designed for in-place cleaning shall have a section of the cl

43、eaned area accessible for inspection or shall provide for other acceptable inspection methods. The manufacturer shall provide written instructions for the cleaning and sanitizing of all food zone surfaces for which in-place cleaning is intended. The type and concentration of sanitizing agent recomme

44、nded in the instructions by the manufacturer shall: comply with 40 CFR 180.9403; or be registered with the USEPA Office of Pesticides Program, Antimicrobials Division as a food contact sanitizer; and if produced by a device, as defined per 40 CFR 152.5003, be demonstrable to be efficacious per USEPA

45、 Pesticide Assessment Guidelines, Subdivision G: Product Performance. The device shall maintain a USEPA site manufacturing device establishment number; and if produced by a device, as defined per 40 CFR 152.5003, have in place and readily discernable to the operator a monitor or indicating device th

46、at reports that the device is producing adequate amounts of sanitizing agent during the sanitization operation. EXAMPLE a corona discharge monitor for ozone-producing devices. 5.1.5 Splash zone surfaces shall be accessible and easily cleanable. 5.1.6 Non-food zone surfaces shall be accessible and cl

47、eanable. 5.1.7 Unexposed non-food zone surfaces shall be accessible or closed. 2017 NSF NSF/ANSI 12 2017 4 5.2 Internal angles and corners, food zone 5.2.1 All internal angles or corners of less than 135 shall be smooth and have radius as set forth below. 5.2.1.1 At the intersection of two planes, w

48、hich result in one angle or corner, the radius shall not be less than 1/8 in (0.13 in, 3.2 mm). 5.2.1.2 At the intersection of three planes, which result in three angles or corners, the radii shall not be less than 1/8 in (0.13 in, 3.2 mm). 5.2.1.3 Lesser radii may be used when necessary to ensure t

49、he proper functioning of equipment components. 5.2.1.4 Greater radii shall be provided, if necessary, to ensure adequate cleaning, maintenance, and product flow. 5.2.2 Solder and other fillet material complying with 4 may be used to achieve the required radii. 5.2.3 For materials other than metal, the radii specified in 5.2.1.1 and 5.2.1.2 shall be effected using parent material or a material proven to be bonded and otherwise equal to or better than the parent material. 5.3 External corners and angles External angles and c
