Full title and description

ASTM F1920-20 — Standard Test Method for Performance of Rack Conveyor Commercial Dishwashing Machines. This standard defines a repeatable laboratory procedure to evaluate the energy and water performance of rack conveyor (including rackless/flight-type) commercial dishwashing machines; it treats tank heaters and booster heaters separately and is intended for both hot-water and chemical sanitizing machines.

Abstract

ASTM F1920-20 provides test procedures to measure energy consumption (including idle rates and heater input) and final-rinse water consumption for rack conveyor commercial dishwashers. The standard establishes pre-test calibration and verification steps (tank and booster temperature calibration, pump and conveyor motor calibration, and final sanitizing rinse calibration) and specifies how to submeter optional heaters (for example prewash or booster) so measured energy/water use can be separated. The procedure explicitly does not address cleaning or sanitizing performance (only energy and water performance).

General information

• Status: Active standard (current edition published 2020).
• Publication date: 1 September 2020.
• Publisher: ASTM International.
• ICS / categories: 97.040.01 (Kitchen equipment in general).
• Edition / version: Designation F1920-20 (2020 edition).
• Number of pages: 19.

Scope

This test method applies to rack conveyor commercial dishwashing machines (single- and multiple-tank, rack and rackless/flight type) and is applicable to both hot-water sanitizing and chemical (low-temperature) sanitizing machines. It covers confirmation procedures to ensure the dishwasher is operating properly prior to performance testing and the measurement procedures for energy usage, idle energy rates, cycle rate, and final rinsing water consumption. The method can be used with machines that have steam-coil heating but excludes machines that use steam injection for tank or booster heating.

Key topics and requirements

• Measurement of energy consumption for wash cycles and idle conditions (including tank heater and booster heater where applicable).
• Calibration and verification procedures prior to testing: maximum tank and booster energy input verification, booster and tank temperature calibration, wash pump and conveyor motor calibration, and final sanitizing rinse water calibration.
• Reporting and submetering guidance so optional heaters (prewash, booster) can be accounted for separately in energy totals.
• Test sequences for washing energy performance, tank heater idle energy rate, and booster idle energy rate (when provided).
• Applicability notes and limits (covers steam-coil heating; excludes steam-injection tanks/boosters; requires machines be set to factory settings unless otherwise documented).

Typical use and users

Used by manufacturers for product development and declared performance, by independent test laboratories and certifiers performing energy/water performance tests, by utilities and rebate programs evaluating eligible models, and by specification writers, procurement officers, and building/facility managers who require standardized energy and water performance data for conveyor-type commercial dishwashers.

Related standards

ASTM F1920-20 is part of the family of ASTM test methods for commercial dishwashers and is commonly referenced alongside ASTM F1696 (single-rack/door-type energy performance). ENERGY STAR, federal procurement guidance (FEMP), and some state/local efficiency programs rely on ASTM methods (including F1920) or equivalent procedures to determine idle energy and water consumption for conveyor machines. Users commonly cross-reference NSF/ANSI test procedures for water consumption and ENERGY STAR/FEMP criteria when demonstrating compliance with efficiency programs.

FAQ

Q: What is this standard?

A: ASTM F1920-20 is a standardized laboratory test method that defines how to measure the energy and final-rinse water performance of rack conveyor commercial dishwashing machines (rack and rackless/flight-type).

Q: What does it cover?

A: It covers pre-test verification and calibration steps (tank/booster energy input and temperatures, pump and conveyor motor calibration, rinse calibration), measurement of washing and idle energy performance, and reporting requirements for separating energy use of optional heaters and components. It does not evaluate cleaning or sanitizing effectiveness.

Q: Who typically uses it?

A: Appliance manufacturers, independent testing laboratories, ENERGY STAR and utility rebate program administrators, government procurement/FEMP teams, specifiers, and large foodservice operators or consultants conducting equipment selection and energy/water lifecycle assessments.

Q: Is it current or superseded?

A: The current active edition is F1920-20 (published September 1, 2020). Earlier editions (for example F1920-15, F1920-11, F1920-07, and older revisions) are historical; users should reference the 2020 edition unless a purchaser or program requires a specific earlier revision.

Q: Is it part of a series?

A: Yes — it is part of ASTM’s food service equipment standards developed under the relevant ASTM committee/subcommittee for commercial dishwashing equipment (related documents include ASTM F1696 for door-type machines and other ASTM test/protocols used alongside NSF/ANSI and ENERGY STAR program criteria).

Q: What are the key keywords?

A: Keywords include booster, conveyor, dishload, dishrack, dishwasher, hot-water sanitizing, tank heater, warewasher, idle energy rate, final rinse water consumption.
