ASTM F2473-12(2023) PDF

Overview

ASTM F2473-12(2023): Standard Test Method for Performance of Water-Bath Rethermalizers provides a comprehensive procedure to evaluate the energy consumption and rethermalizing performance of floor-model and countertop water-bath rethermalizers used in commercial and institutional food service settings. This standard, developed by the ASTM Committee F26 on Food Service Equipment, supports food service operators and equipment manufacturers in making informed decisions regarding the selection, operation, and benchmarking of water-bath rethermalizers. The test method is applicable to both gas and electric models, ensuring broad industry relevance.

Key Topics

• Energy Input Rate: Verifies that the rethermalizer operates in accordance with its nameplate energy rating. This ensures compliance with manufacturer specifications and supports accurate equipment comparisons.
• Temperature Calibration: Assures that the rethermalizer maintains the specified water temperature, which is critical for both food safety and consistent culinary results. This section also aids in calibrating thermostat controls.
• Preheat Energy and Time: Evaluates the energy and time required for the unit to reach operating temperature from ambient. This data enables food service operators to plan for startup periods and energy budgeting.
• Idle and Pilot Energy Rate: Measures energy consumption when the unit is not actively rethermalizing, offering insights into operational efficiency during standby periods.
• Production Capacity: Determines the maximum rate at which the rethermalizer can heat food, assisting operators in selecting equipment based on output needs.
• Retherm-Energy Efficiency: Provides a key performance metric showing how efficiently the unit transfers energy to the food during a typical full-load rethermalizing cycle.

Applications

• Food Service Equipment Selection: Using the objectively measured parameters in ASTM F2473-12(2023), food service operators can identify water-bath rethermalizers that best match their required production capacities and energy targets.
• Operational Cost Management: Idle and pilot energy rates, as well as preheat energy metrics, provide actionable data for energy conservation and budgeting in kitchens.
• Regulatory Compliance and Consistency: By following a standardized test method, manufacturers and commercial kitchens can ensure consistency in equipment performance reporting, supporting regulatory, safety, and procurement standards.
• Maintenance and Calibration: Routine verification using this standard can identify when recalibration or maintenance is needed, helping maintain optimal operation and energy efficiency.
