ISO 764-1984 rus PDF

Full title and description

ISO 764:1984 — Horology — Antimagnetic (magnetic resistant) watches. This record refers to the International Organization for Standardization (ISO) edition published in April 1984 and to versions available in multiple languages (English/French) including Russian-language distribution references.

Abstract

Specifies minimum requirements and describes the corresponding test method for watches claimed to be antimagnetic (magnetic resistant). The test is based on the simulation of an accidental exposure of a watch to a direct-current magnetic field of 4 800 A/m.

General information

• Status: Withdrawn / superseded.
• Publication date: April 1984 (published 1 April 1984).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 39.040.10 (Watches, horology).
• Edition / version: Edition 2 (1984).
• Number of pages: 2 pages.

Details above are taken from the ISO catalogue entry for the 1984 edition.

Scope

Applies to watches intended for general use that are marketed or claimed as antimagnetic / magnetic resistant. The standard sets minimum performance requirements and a reproducible test procedure that simulates accidental exposure to a static magnetic field (4 800 A/m) to evaluate the behaviour and accuracy of the watch after exposure. It is primarily intended to provide a common basis for manufacturers, test laboratories and conformity assessment bodies.

Key topics and requirements

• Definition and classification of watches described as antimagnetic / magnetic resistant.
• Minimum magnetic-field intensity used for the basic test (direct-current field of 4 800 A/m) and the test simulation approach.
• Test procedure to expose a watch to the specified magnetic field and observe functional/accuracy effects.
• Acceptance criteria addressing continued functioning and permissible change in timekeeping after exposure (manufacturer and test-laboratory assessment).
• Marking/label guidance for watches designated as magnetic resistant (expanded in later revisions of the standard).

Key technical points and test-basis drawn from the ISO standard text and later revision notes.

Typical use and users

Used by watch manufacturers and designers to specify and verify magnetic resistance performance; by independent test laboratories and conformity assessment bodies for product testing; by watchmakers and repair technicians for service and diagnosis; and by procurement/specification professionals and regulators when referencing minimum magnetic-resistance requirements for wrist and pocket watches.

Related standards

ISO 764:1984 is part of a sequence of ISO publications on magnetic resistance for watches. It superseded ISO 764:1973 and was later revised by ISO 764:2002 (edition 3, 2002) and ultimately replaced by ISO 764:2020 (edition 4, published February 2020). For current requirements and marking rules, consult ISO 764:2020.

FAQ

Q: What is this standard?

A: ISO 764:1984 is an ISO international standard titled "Horology — Antimagnetic (magnetic resistant) watches" that specified minimum requirements and a test method for watches claimed to be antimagnetic.

Q: What does it cover?

A: It covers the basic definition of antimagnetic (magnetic resistant) watches, a reproducible test procedure simulating accidental exposure to a 4 800 A/m direct-current magnetic field, and the performance considerations to be checked after exposure.

Q: Who typically uses it?

A: Watch manufacturers, test laboratories, conformity-assessment organizations, watchmakers/repair technicians, procurement specialists and standards/regulatory bodies concerned with watch performance and labeling.

Q: Is it current or superseded?

A: ISO 764:1984 has been withdrawn. The ISO lifecycle records a formal withdrawal of older editions and the standard was revised (ISO 764:2002) and later replaced by ISO 764:2020 (published February 2020). The withdrawal of the 1984 edition is recorded in ISO lifecycle information (withdrawal stage recorded in July 2002). For current requirements use ISO 764:2020.

Q: Is it part of a series?

A: Yes — ISO 764 exists as a series of revisions addressing the same subject: ISO 764:1973 → ISO 764:1984 → ISO 764:2002 → ISO 764:2020 (current). Each later edition revises and expands the test methods, requirements and marking guidance.

Q: What are the key keywords?

A: Antimagnetic, magnetic resistant, watches, horology, 4800 A/m, test method, ISO 764, watch marking.
