ISO 1992-8-1978 PDF

Full title and description

ISO 1992-8:1978 — Commercial refrigerated cabinets — Test methods — Part 8: Test for accidental mechanical contact. This short technical standard defines a mechanical-access test procedure (using standardized test fingers/probes) to verify protection against accidental contact through openings in commercial refrigerated display cabinets intended for the sale and/or display of food products.

Abstract

ISO 1992-8:1978 specifies a test method to assess protection of users from accidental mechanical contact with hazardous parts of commercial refrigerated cabinets via openings. The method establishes the use of standard test probes (jointed/unjointed test fingers as referenced from IEC probe practice) and the conditions under which access attempts are made to determine whether the cabinet construction prevents hazardous contact under normal use.

Scope

This part of ISO 1992 applies to commercial refrigerated cabinets intended for the sale and/or display of foodstuffs. It describes a mechanical-access test — a procedure using standardized test fingers/probes to simulate accidental insertion of a human finger (or similar object) through openings, grilles or gaps to check whether hazardous mechanical or live parts can be touched. It does not specify tests for accidental electrical contact; for electrical contact hazards it refers users to the appropriate IEC test probe methods.

Key topics and requirements

• Definition of the test objective: verifying protection against accidental mechanical contact through openings.
• Use of standardized probes/test fingers (jointed and/or unjointed) to simulate human access.
• Specified probe dimensions and basic application method (force, direction, openings to be tested).
• Identification of cabinet areas and openings to be tested (service openings, ventilation slots, display apertures, control access points).
• Pass/fail criteria based on whether the probe can reach hazardous parts or not.
• Reference to IEC probe practice for probe construction and for electrical-contact testing where applicable.

Typical use and users

Manufacturers of commercial refrigerated display cabinets, independent testing laboratories, conformity assessment bodies, safety engineers and product designers use this standard (historically) to demonstrate that cabinet designs provide basic protection against accidental finger access to hazardous parts. Regulatory authorities and purchasers may reference the method when evaluating safety of display cabinets. Note: the standard has been withdrawn and modern design/testing typically follows later consolidated display-cabinet standards.

Related standards

ISO 1992 is a multipart series (methods of test for commercial refrigerated cabinets). Several parts of ISO 1992 have been withdrawn or superseded and the refrigerated display cabinet family has since been consolidated into newer standards (for example, the ISO 23953 series covering refrigerated display cabinets and related test methods). In addition, IEC standards that define probe/test-finger dimensions and use (such as IEC 61032 and related IEC/EN safety and IP test guidance) are referenced for probe construction and electrical-access testing. Other related ISO documents in the refrigeration/display domain include ISO 22041, ISO 22042, ISO 22043 and ISO 22044 (product-type performance and classification standards).

FAQ

Q: What is this standard?

A: ISO 1992-8:1978 is Part 8 of the ISO 1992 series, a short international test-method document that defined a test for accidental mechanical contact on commercial refrigerated cabinets (using standardized test probes).

Q: What does it cover?

A: It covers a mechanical-access test procedure to check whether openings in refrigerated display cabinets permit accidental contact with hazardous mechanical or live parts. It specifies use of standard test probes (test fingers) and the basic pass/fail concept for such protection tests.

Q: Who typically uses it?

A: Historically, cabinet manufacturers, product designers, conformity assessment and test laboratories, safety engineers and procurement/regulatory bodies used this part when assessing or certifying cabinet safety.

Q: Is it current or superseded?

A: ISO 1992-8:1978 is withdrawn. Its subject matter has been taken into account in later, consolidated standards for refrigerated display cabinets (for example the ISO 23953 series and other more recent ISO/IEC safety and test documents). Users should refer to the current ISO 23953 parts and the appropriate IEC probe/safety standards for up-to-date test methods.

Q: Is it part of a series?

A: Yes — it is Part 8 of the ISO 1992 series (Commercial refrigerated cabinets — Methods of test). Several other parts exist in the ISO 1992 series; many of those parts have since been withdrawn or revised and the overall subject has been consolidated into newer standards for refrigerated/display cabinets.

Q: What are the key keywords?

A: commercial refrigerated cabinets; refrigerated display cabinets; test methods; accidental mechanical contact; test finger; IEC probe; cabinet safety; openings; protection against access.
