2  DEFINITIONS

2.1 Accessible: A surface which is or can be quickly exposed for inspection and cleaning, using simple tools normally used by operating or cleaning personnel, such as screw drivers or wrenches.

2.1.1 Readily Accessible: A surface, which is or can be easily and quickly exposed for inspection and cleaning without the use of tools.

2.2 Cleanability: Made of such materials, so finished, and so fabricated that soil may be effectively removed by normal cleaning means. (ASME/ANSI F2.1-1986)

2.2 Cleaning in Place (CIP): A procedure dependent upon circulating appropriate cleaning solutions at relatively high velocities for a specified time and temperature in a closed system specifically designed for this purpose.

2.2.1 The 3A Accepted Practices for Permanently Installed Sanitary Product Pipelines and Cleaning Systems shall be used as guidelines in determining design criteria for products that are highly perishable.

2.2.2. When specific Clean-in-Place (CIP) procedures are developed, they shall be included in this definition.

2.3 Cleaning Out of Place (COP): A method of removing the equipment to an area remote to the operating area that will allow complete cleaning.

2.4 Closed: Fitted together tightly with no openings large enough to permit the entry or harborage of vermin, including insects.

2.5 Corrosion Resistant: A material that maintains its surface characteristics under prolonged influence of the normal components of the environment, such as product, ingredients, ambient conditions, and cleaning material.

2.6 Dead End: A place wherein product, ingredients, and cleaning agents, or extraneous matter may be trapped, retained or not completely displaced in normal operation or cleaning procedures.

2.7 Equipment Disassembly Procedures: Detailed, written equipment disassembly procedures provided by the manufacturer to allow end-user to adequately clean the machine.

2.8 In-Place Cleaning (IPC)

2.8.1 Mechanical Cleaning: A procedure for using compressed air or vacuum to adequately remove dust, scrap, and residue to provide dry cleaning.

2.8.2 Wash Down Design: Stationary equipment designed to allow complete washing with a high pressure hose, using water and cleaning agents, with no difference in operating characteristics at end of wash down cycle.

2.9 Non-Absorbent: A material under ordinary conditions of use, that will not retain an amount of the substances with which it normally comes in contact nor be affected adversely or affect adversely the product or ingredients with which it comes in contact, or create an unsanitary condition.

2.9.1 The 3A Sanitary Standards tests for Rubber and Rubber-Like Materials, and the 3A Sanitary Standards tests for Multiple-Use Plastic Materials, shall be used as the criteria for determining compliance of such materials with this definition.

2.9.2 When absorbency tests are developed for other materials, they shall be included in this definition.

2.10 Non-Toxic: Materials, which under conditions of their use, conform to the procedures and requirements of the U.S. Food and Drug Administration as being non-toxic.

2.11 Product Zone: All surfaces of the equipment with which product or ingredients may normally come in contact and return to the product or ingredients.

2.11.1 Non-Product Zone: All surfaces outside the product zone as defined in Section 2.11.

2.12 Protective Coating: A protective coating shall prevent corrosion of the base material, shall not affect or be affected by the substances in contact with it, shall be non-toxic, non-absorbent, shall not impart an odor or taste to the product, and shall be bonded to the underlying surface so as to be resistant to chipping and peeling. It shall have a durable, smooth surface without breaks exposing the base material, shall resist abrasion in ordinary use, and shall maintain its surface characteristics under prolonged influence of the environment such as the product, and cleaning agents.

2.13 Removable: A part which can be quickly separated from the machine or equipment, using simple tools normally used by operating or cleaning personnel, such as screw drivers or wrenches.

2.13.1 Readily Removable: A part, which can be easily and quickly separated from the equipment without the use of tools.

2.14 Sealed: The condition resulting from the filling of a crack, crevice, joint or opening, so as to effectively prevent the entry or passage of moisture, liquids, gases, and solids.

2.15 Shall: When the verb "shall" is used, the requirements of these standards can be met only by literal compliance.

2.16 Should: Use of the verb "should" indicates a preferred condition.

2.17 Smooth: A uniform surface free of pits, crevices and scale. Within the product zone, surface roughness height shall be no greater than 1.8 micron (70 micro inches) Arithmetic Average.

2.18 Special Disassembly Tools and Equipment: The detailed list provided by the manufacturer, of tools and/or special equipment that may be required to disassemble the certified machine to insure satisfactory cleaning.

2.19 Sufficient Clearance: Shall mean designed and installed to permit complete access to all areas for inspection and cleaning.
