ISO 10110-4-1997 PDF

Full title and description

ISO 10110-4:1997 — Optics and optical instruments — Preparation of drawings for optical elements and systems — Part 4: Material imperfections — Inhomogeneity and striae. This part gives rules for indicating allowable inhomogeneity (refractive-index variations) and striae (localized filamentary index changes) on technical drawings of optical elements.

Abstract

Part 4 of ISO 10110 specifies presentation and notation rules used on manufacturing and inspection drawings to describe material inhomogeneity and striae in optical elements. It defines classes, notation conventions and how to record limits so that design intent, acceptance criteria and inspection requirements are unambiguous.

General information

• Status: Withdrawn / historically published (has been superseded in the consolidated ISO 10110 work).
• Publication date: 1997 (published in mid–1997; often listed as August 1997).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 37.020 (Optical equipment) and 01.100.20 (Mechanical engineering drawings).
• Edition / version: First edition — ISO 10110-4:1997.
• Number of pages: ISO edition typically listed as 4 pages (national/adopted versions and publisher listings vary; some national/adopted documents or national reprints list additional editorial front matter).

Scope

Specifies how to indicate limits and classes for refractive-index inhomogeneity and for striae on technical drawings of optical elements, so manufacturers and inspectors can apply consistent acceptance criteria. The broader ISO 10110 series covers the presentation of design and functional requirements for optical elements and systems.

Key topics and requirements

• Definitions of inhomogeneity and striae and their optical effects (wavefront distortion, stray light, transmission loss).
• Classification scheme for inhomogeneity and for striae (class numbers/letters used to indicate permissible levels on drawings).
• Notation and drawing practice (how to place the designation on element drawings and in tables).
• Rules for combining material-imperfection indications with other ISO 10110 tolerancing notation used on optical drawings.
• Guidance to ensure unambiguous communication between designers, manufacturers and quality/inspection teams.

Typical use and users

Used when specifying optical glass or finished optical elements where refractive-index uniformity matters. Typical users include optical designers, lens/system engineers, drawing drafters preparing ISO 10110–style specifications, procurement/specification engineers, manufacturing engineers and quality/inspection personnel responsible for incoming material and finished-part acceptance.

Related standards

ISO 10110 is a multipart series; closely related parts include ISO 10110‑1 (General), ISO 10110‑2 (Stress birefringence), ISO 10110‑3 (Bubbles and inclusions), ISO 10110‑5 (Surface form tolerances) and others. The material-imperfection content of Part 4 was later consolidated into the newer Part 18 (ISO 10110‑18:2018), which revises/replaces the historical Part 4 content.

FAQ

Q: What is this standard?

A: ISO 10110-4:1997 is the part of the ISO 10110 series that defined how to indicate and classify material inhomogeneity and striae on technical drawings for optical elements.

Q: What does it cover?

A: It covers definitions, classification schemes, notation and drawing practice for allowable refractive-index inhomogeneity and for striae (localized index disturbances), so acceptance and inspection criteria can be unambiguously recorded on engineering drawings.

Q: Who typically uses it?

A: Optical designers, lens manufacturers, drawing/engineering offices, procurement/specification writers and inspection/quality engineers who need to communicate material-uniformity requirements for optical components.

Q: Is it current or superseded?

A: The 1997 Part 4 is a historical/withdrawn item in many catalogs and its material-imperfection content has been consolidated into ISO 10110-18 (published 2018). Users should reference ISO 10110-18:2018 (and the current ISO 10110‑series parts) for up-to-date, consolidated rules.

Q: Is it part of a series?

A: Yes — ISO 10110 is a multipart standard (multiple parts addressing general rules, material imperfections, surface form, centring, surface imperfections, surface texture, coatings, etc.). Part 4 is one historical part of that series.

Q: What are the key keywords?

A: Inhomogeneity, striae, material imperfections, optical drawings, ISO 10110, refractive-index variation, optical specification, inspection criteria.
