Full title and description

Optics and optical instruments — Ophthalmic optics — Marking of spectacle frames. Specifies the information that shall be marked on spectacle frames and the preferred locations for that information; gives recommendations for additional information in accompanying documentation.

Abstract

Specifies the information to be marked on spectacle frames and its location, and provides recommendations for further information in documentation accompanying the frames (Annex A is informative). Intended to standardize identification and marking practices for spectacle frames.

General information

• Status: Withdrawn.
• Publication date: November 1991 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 11.040.70 (Ophthalmic equipment / ophthalmic optics).
• Edition / version: Edition 1 (1991).
• Number of pages: 3 (ISO original document).

Scope

Gives the minimum marking information and recommended locations on spectacle frames and suggests additional information that may be provided in accompanying documentation or separately. The standard applies to marking practice for spectacle frames (information, placement and informative examples).

Key topics and requirements

• Defined marking requirements — which information should appear on frames and where it should be placed.
• Recommendations for supplementary information to be included in documentation accompanying the frames.
• Informative annex with examples and guidance for implementation.
• Relationship to subsequent consolidated requirements for spectacle frames (later incorporated into ISO 12870 series).

Typical use and users

Frame manufacturers and suppliers, retailers, conformity assessment and testing laboratories, product designers and standards committees use the standard to ensure consistent marking and identification of spectacle frames at point of sale and in technical documentation. Regulatory and procurement bodies may reference its requirements when applicable.

Related standards

Replaced / consolidated into the ISO 12870 series (ISO 12870:2004 and later revisions). National and regional adoptions (EN/ISO versions) have existed; many jurisdictions later referenced ISO 12870 for comprehensive frame requirements.

FAQ

Q: What is this standard?

A: ISO 9456:1991 is an International Standard for ophthalmic optics that specifies the information to be marked on spectacle frames and recommended locations for that information.

Q: What does it cover?

A: It covers the mandatory and recommended markings on spectacle frames, guidance on where markings should be placed, and provides informative examples and recommendations for accompanying documentation.

Q: Who typically uses it?

A: Manufacturers and suppliers of spectacle frames, retailers, testing and conformity-assessment bodies, designers and standards committees concerned with ophthalmic products and product identification.

Q: Is it current or superseded?

A: ISO 9456:1991 has been withdrawn and its subject matter was incorporated into the ISO 12870 series (ISO 12870:2004 and subsequent revisions). Users should consult the latest ISO 12870 edition for current requirements.

Q: Is it part of a series?

A: Yes — it sits within the ophthalmic optics activity of ISO/TC 172/SC 7 and was later superseded by the ISO 12870 sequence of standards addressing spectacle-frame requirements and test methods.
