Full title and description

Commercial refrigerated cabinets — Methods of test — Part 5: Water vapour condensation test. This international standard specifies a laboratory test procedure to determine and characterize water-vapour condensation on commercial refrigerated cabinets intended for the sale and/or display of food products.

Abstract

Defines the water vapour condensation test for commercial refrigerated display cabinets, describing required test conditions, sample preparation and the general method used to assess condensation behaviour when cabinets are tested under the same conditions as established for the temperature and defrosting tests in the ISO 1992 series.

General information

• Status: Withdrawn (withdrawal of the original ISO 1992 series; replaced by later standards in the ISO 23953 series).
• Publication date: 1974-04 (First edition, 1974).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 97.130.20 (Refrigeration and heat pumps / commercial refrigerated cabinets).
• Edition / version: Edition 1 (1974).
• Number of pages: 1 page (short procedural standard).

Scope

This part of ISO 1992 sets out the test method to evaluate water‑vapour condensation on commercial refrigerated cabinets used for display or sale of foodstuffs. It applies when cabinets are tested under the same environmental and operating conditions used for temperature and defrosting tests (other parts of ISO 1992). The scope is limited to laboratory test conditions and to the measurement/observation of condensation rather than design requirements.

Key topics and requirements

• Test environment and controlled conditions: specified ambient temperature and humidity for condensation assessment.
• Specimen preparation and loading to represent typical commercial display conditions.
• Observation and measurement of water-vapour condensation (location, onset, amount and persistence).
• Relationship to temperature and defrosting tests — the condensation test is applied under the same conditions as parts 3 and 4 of ISO 1992.
• Reporting requirements: how to record results, test conditions and any visual or measured condensation findings.

Typical use and users

Manufacturers of commercial refrigerated cabinets, independent testing laboratories, conformity assessment bodies, specifiers and standards committees use this test method to evaluate condensation performance of display cabinets. The test was intended to support product development, comparison between models and to provide reproducible data for procurement and regulatory specifications.

Related standards

This part was one element of the ISO 1992 series (commercial refrigerated cabinets — methods of test). ISO 1992-5:1974 has been withdrawn and its subject matter has been replaced and consolidated in the later ISO 23953 series (parts addressing refrigerated display cabinets and relevant test methods). Other related national and international refrigeration test standards and parts of the original ISO 1992 series (temperature, defrost tests and dimensional calculations) are also relevant for a complete test programme.

FAQ

Q: What is this standard?

A: ISO 1992-5:1974 is Part 5 of the ISO 1992 series titled "Commercial refrigerated cabinets — Methods of test", specifically describing a water‑vapour condensation test procedure for refrigerated display cabinets.

Q: What does it cover?

A: It covers a laboratory procedure to assess and record water‑vapour condensation on commercial refrigerated cabinets when tested under defined environmental and operating conditions (aligned with the temperature and defrosting tests in the ISO 1992 series).

Q: Who typically uses it?

A: Cabinet manufacturers, test laboratories, conformity assessors, product specifiers and standards developers use the method to evaluate condensation behaviour for design, quality control and procurement purposes.

Q: Is it current or superseded?

A: ISO 1992-5:1974 has been withdrawn. Its subject matter has been superseded and incorporated into later standards in the ISO 23953 series that cover refrigerated display cabinets and associated test methods. Users should consult the ISO 23953 series for current, supported test requirements.

Q: Is it part of a series?

A: Yes — it was part of the ISO 1992 series (multiple parts covering dimensions, temperature tests, defrost tests and condensation). The original ISO 1992 series has been withdrawn and consolidated into newer standards addressing refrigerated display cabinets.

Q: What are the key keywords?

A: Condensation, water vapour, refrigerated display cabinet, test method, defrosting, temperature test, ISO 1992, ISO 23953.
