Heat shall be provided to the washer through steam (Style 1) by injection (Class A) or heat exchange coil (Class B) or through electric means (Style 2). The washer and its components shall be manufactured free of defects. Piping and fittings shall be manufactured from corrosion-resisting material or heat-resisting plastic material. Valves, spray assemblies, and overflow drain shall be manufactured from corrosion-resisting materials. Tank and housing shall be constructed of corrosion-resistant steel. Scrap trays (strainers), access door/s, and legs shall be constructed of corrosion-resistant steel or other corrosion-resisting material. The pump motor shall be mounted on the tank or rigid steel base, with the pump casing being of cast iron or corrosion-resisting material. When specified, a final rinse booster heater and/or detergent feeder may be provided. The washer shall be operated at ambient room temperature. Tests for performance standards and operational compliance as well as for noise level, leakage, energy, and productivity requirements shall be performed and shall conform to the requirements specified.

Overview

ASTM F1202-22 is the standard specification established by ASTM for washing machines used in commercial food service settings, specifically motor-driven, vertically oscillating arm type machines for cleaning pots, pans, and utensils. This standard outlines design, construction, performance, and safety requirements for these machines, ensuring effective cleaning and heat sanitization in demanding commercial environments. Compliance with ASTM F1202-22 helps guarantee high levels of hygiene, durability, and operational reliability for food service operators.

Key Topics

• Applicability: Covers manually fed, automatically controlled, motor-driven pot, pan, and utensil washing machines, with vertically oscillating arms for thorough cleaning and sanitization.
• Machine Types and Styles:
  • Type I: One rack capacity.
  • Style A: Single door, front-loading.
  • Style B: Three-door, pass-through with front inspection door.
• Heating Methods:
  • Style 1: Steam heated (by injection or heat exchange coil).
  • Style 2: Electric heat.
• Construction and Material:
  • Corrosion-resistant steel required for tanks, housings, and key components.
  • Use of approved materials for piping, valves, spray assemblies, and strainers to ensure durability and sanitation.
• Performance Criteria:
  • Must meet energy, productivity, noise level (max 80 dB), and leakage requirements.
  • Machines must wash, rinse, and heat sanitize per food safety standards.
• Safety and Marking:
  • Electrical controls must conform to recognized safety standards.
  • Data plate and instruction plate required for identification and safe operation.
  • Equipment must be safe for operators and maintain hygienic conditions.

Applications

ASTM F1202-22 is vital for businesses where large-scale washing of cookware and utensils is frequent and diligent sanitation is required. Key application areas include:

• Commercial Kitchens: Restaurants, cafeterias, and catering facilities relying on robust washing machines to ensure rapid, sanitary turnaround of pots, pans, and utensils.
• Institutional Food Service: Schools, hospitals, and correctional facilities where volume and health standards necessitate reliable and compliant warewashing equipment.
• Industrial Food Processing: Manufacturers and processors needing standardized, high-capacity washing solutions for equipment and utensils.
• Food Service Equipment Procurement: Helps buyers and specifiers ensure that their chosen commercial pot and pan washers meet recognized international requirements for safety, energy efficiency, and hygiene.

water rinse valves shall be reliable and fully automatic and suitable for 210°F (98.9°C) water. The manually operated valves, when
used, shall be identified. When specified (see 5.1.2), a water pressure reducing valve shall be provided for reducing water pressure
to 20 6 5 psi (137.8 6 34.4 kPa) (see ANSI SI.4 and ANSI SI.13).
7.5 Spray Assemblies—All spray nozzles and spray arm manifolds shall be of corrosion-resisting materials. The main spray arm
assembly shall include separate wash and rinse pipes. The assembly shall be directly connected by means of a rod-cam device. The
assembly shall oscillate thereby moving the spray arms vertically between racked ware. A secondary spray assembly consisting
of water-driven rotary sprays shall be installed under the work rack.
7.6 Tank and Housing—The tank and housing shall be constructed of not less than 0.070-in. (1.78 mm) corrosion-resistant steel.
