DIN EN ISO 13666 1998-11 PDF

Full title and description

STB / DIN EN ISO 13666:1998-11 — Ophthalmic optics — Spectacle lenses — Vocabulary. This is the DIN/EN adoption of ISO 13666 (first edition, 1998), a vocabulary standard that defines terms used for blanks, finished spectacle lenses and fitting purposes.

Abstract

Defines standardized terminology for ophthalmic optics specifically relating to spectacle lens blanks and finished lenses and for fitting purposes. It excludes most process- and material-related terms and defect terminology (see ISO 9802 for those aspects). The original ISO edition (1998) has been withdrawn and later revised by subsequent ISO editions.

General information

• Publication date: Original ISO publication 26 August 1998; DIN EN ISO adoption/publication recorded November 1998 (1998-11-01 in DIN catalogues).
• Publisher: International Organization for Standardization (ISO); national adoption published by DIN as DIN EN ISO 13666.
• ICS / categories: 01.040.11 (Vocabularies — health care technology), 11.040.70 (Ophthalmic equipment).
• Edition / version: Edition 1 (ISO 13666:1998) / DIN adoption DIN EN ISO 13666:1998-11.
• Number of pages: Approximately 59 pages (ISO edition 1998).

Scope

Specifies terms and definitions used in the field of ophthalmic optics for semifinished spectacle lens blanks, finished spectacle lenses and aspects of fitting. The standard provides consistent vocabulary to be used by manufacturers, laboratories, opticians, researchers and standards committees. It explicitly excludes detailed process, material and defect terminology (these are covered in ISO 9802 and other related ophthalmic optics standards).

Key topics and requirements

• Standardized definitions for blanks, finished lenses and fitting-related terms.
• Definitions for optical properties and geometrical descriptors used in spectacle lenses (e.g., dioptric power, off-axis power, progressive lens terms, progressive/degressive design language).
• Terminology for lens treatments and surface features where vocabulary is appropriate (coatings and some coating-related terms are addressed; detailed coating test requirements are in separate standards such as ISO 8980 series).
• Clarification of which terms belong in this vocabulary versus those assigned to process/material/defect standards (reference to ISO 9802 for fabrication/material/defect terms).

Typical use and users

Used by spectacle-lens manufacturers, optical laboratories, dispensing opticians, product designers, test laboratories, certification bodies and national standards organisations to ensure consistent use of terms in specifications, test reports, product documentation and regulatory/contractual texts.

Related standards

Replaced/revised editions and closely related ophthalmic optics standards include ISO 13666 (later editions, notably ISO 13666:2019), the ISO 8980 series (specifications and test methods for finished spectacle lenses and coatings), ISO 9802 (terms for processes, materials and defects), and national adoptions such as DIN EN ISO 13666 and related DIN documents (e.g., DIN 58208 referenced in national replacement history).

FAQ

Q: What is this standard?

A: DIN EN ISO 13666:1998-11 is the German/EN adoption of ISO 13666 (1998), a vocabulary standard for ophthalmic optics covering terms for spectacle lens blanks, finished lenses and fitting purposes.

Q: What does it cover?

A: It provides standardized definitions and terminology used across the spectacle-lens supply chain — optical and geometrical terms, fitting language and selected coating-related vocabulary. It does not set test limits or detailed performance requirements; those are in other ISO standards (for example the ISO 8980 series and ISO 9802 for process/material/defect terms).

Q: Who typically uses it?

A: Lens manufacturers, opticians and dispensing laboratories, test and certification bodies, standards committees and technical authors who need unambiguous terminology when writing specifications, reports or regulatory documents.

Q: Is it current or superseded?

A: The 1998 edition has been withdrawn and later revised; the vocabulary was updated in subsequent ISO editions (see ISO 13666:2019 and later national adoptions). Users should reference the most recent edition of ISO 13666 for current definitions.

Q: Is it part of a series?

A: Yes — ISO 13666 is part of the body of ophthalmic optics standards developed by ISO/TC 172/SC 7 and is intended to be used in conjunction with product- and test-focused standards such as the ISO 8980 series (finished lens specifications and coating tests), ISO 9802 (process/material/defect terminology) and other ophthalmic optics documents.

Q: What are the key keywords?

A: Ophthalmic optics, spectacle lenses, vocabulary, lens blanks, finished lenses, fitting, dioptric power, progressive lens terminology, coatings.
