Full title and description

ISO 22042:2021/Amd 1:2024 — Blast chiller and freezer cabinets for professional use — Classification, requirements and test conditions — Amendment 1. This amendment updates and clarifies classification criteria, performance requirements and test conditions for blast chiller and blast freezer cabinets used in professional food‑service and industrial applications, and is published as Amendment 1 to ISO 22042:2021.

Abstract

This amendment refines definitions, test loads and measurement procedures and provides updated reporting requirements for performance testing of blast chillers and blast freezers. Key changes include clarified test‑load specification and tolerances, defined measurement intervals during cooling tests, explicit performance time limits for chilling and freezing tests, and updated energy‑consumption calculation and reporting formats to improve repeatability and comparability of test results. The amendment is short (2 pages) and intended to be read together with ISO 22042:2021.

Scope

This amendment applies to blast chiller and blast freezer cabinets intended for professional use and supplements ISO 22042:2021. It specifies clarified requirements and test conditions for classification and performance verification of these appliances, including test‑load definitions, measurement frequency and reporting information. The amendment is intended to be used in conjunction with the main ISO 22042:2021 text and does not replace the base standard.

Key topics and requirements

• Refined definitions and classification criteria for blast chillers and blast freezers to ensure consistent interpretation in testing.
• Test‑load specification and tolerances (load consistency requirements to standardize test conditions).
• Performance test time limits (examples cited in guidance: typical chilled‑food test completion within 120 minutes and frozen‑food test windows up to 270 minutes under specified conditions).
• Minimum measurement frequency for temperature recording during tests (measurements at short, regular intervals — e.g., every 5 minutes — to track cooling curves).
• Energy‑consumption calculation clarified to be referenced to full‑load conditions for comparability.
• Updated reporting and information formats to improve clarity and harmonize test result presentation.

Typical use and users

Manufacturers of professional blast chillers/freezers, independent test laboratories, certification bodies, buyers and procurement teams in commercial catering and food processing, food safety and quality engineers, and standards committees use this amendment to ensure that performance tests are conducted and reported consistently and that product specifications and procurement requirements reference the latest testing expectations.

FAQ

Q: What is this standard?

A: ISO 22042:2021/Amd 1:2024 is Amendment 1 to ISO 22042:2021, titled "Blast chiller and freezer cabinets for professional use — Classification, requirements and test conditions". It provides clarifications and updates to the original 2021 standard.

Q: What does it cover?

A: It covers clarified definitions, classification criteria, specified test loads and tolerances, measurement intervals during performance tests, time limits used for chill and freeze performance checks, energy‑consumption calculation rules and updated reporting formats. The amendment is intended to be used alongside ISO 22042:2021.

Q: Who typically uses it?

A: Manufacturers, test laboratories, conformity assessment and certification bodies, procurement/specification teams in commercial kitchens and food processing, and regulatory or standards staff concerned with performance and safety of professional refrigeration equipment.

Q: Is it current or superseded?

A: It is current as an amendment published in February 2024; it amends and must be read together with ISO 22042:2021. The amendment itself does not supersede the base standard but modifies certain clauses and test provisions.

Q: Is it part of a series?

A: The document is an amendment to ISO 22042:2021. It is produced under the work of ISO/TC 86/SC 7 (testing and rating of commercial refrigerated appliances) and sits alongside other ISO standards covering commercial refrigeration test methods and performance (for example standards governing refrigerated display cabinets and related test procedures).
