Full title and description

ISO 10110-11:2025 — Optics and photonics — Preparation of drawings for optical elements and systems — Part 11: Non-toleranced data. This part of the ISO 10110 series specifies the default (implicit) tolerances and rules that apply when tolerances or values are not explicitly indicated on drawings for optical elements and systems.

Abstract

ISO 10110-11:2025 defines default (implicit) tolerances to be used in ISO 10110 drawing indications when specific values are missing. The defaults are intended to provide consistent fabrication and inspection expectations for finished optical elements and reduce ambiguity where indication codes or values are omitted.

Scope

This document specifies the default (implicit) tolerances that apply to indications in the ISO 10110 series when those indications lack explicit values. It is intended to standardize how missing or incomplete indication codes are interpreted so that designers, manufacturers and inspectors have common, conservative defaults for finished optical elements. The standard applies across the ISO 10110 drawing convention framework for optical elements and systems.

Key topics and requirements

• Defines default tolerances (implicit values) for key drawing indications when no explicit values are provided.
• Defaults may depend on part size (for example, ranges based on diagonal or characteristic dimensions).
• An indication code with no values (e.g., a code shown without numeric entries) is treated as missing and triggers the applicable defaults.
• A dash or explicit “no default” marker after a code means no default tolerance is applied for that property.
• For surface form and testing-area-related rules, defaults only apply when the entire indication (code and values) is absent; related measurement and form-tolerance rules reference ISO 10110-5 and other parts.
• Normative relationships to other ISO 10110 parts (general rules in Part 1 and specific test/tolerance parts) are specified to ensure consistent interpretation.

Typical use and users

Used by optical designers, mechanical and optical drawing drafters, manufacturing engineers, quality/inspection teams, and subcontractors who produce or verify optical elements. Typical applications include interpretation of legacy drawings with missing values, preparing ISO 10110-compliant drawings, and establishing minimum fabrication/inspection expectations when designers omit explicit tolerances.

FAQ

Q: What is this standard?

A: ISO 10110-11:2025 is the part of the ISO 10110 series that defines default (implicit) tolerances and rules for drawing indications when explicit tolerances or values are missing from optical-element drawings.

Q: What does it cover?

A: It covers the assignment and interpretation of default tolerances for various drawing indication codes, rules for when defaults apply (for example when codes are omitted or values are missing), and how those defaults interact with other ISO 10110 parts that govern surface form, texture and inspection.

Q: Who typically uses it?

A: Optical designers, CAD/drafting teams, manufacturing engineers, inspection and quality personnel, procurement teams and optical subcontractors who need to interpret or produce ISO 10110-compliant drawings. It is especially useful when working with drawings that lack explicit tolerance values.

Q: Is it current or superseded?

A: Current. ISO 10110-11:2025 was published in March 2025 (Edition 3) and replaces the withdrawn ISO 10110-11:2016 edition.

Q: Is it part of a series?

A: Yes — it is Part 11 of the ISO 10110 series (Preparation of drawings for optical elements and systems). The series contains multiple parts addressing general drawing rules, surface form, texture, centring, aspheres and material imperfections; Part 11 provides the defaults to be used when specific tolerances are omitted.

Q: What are the key keywords?

A: Non-toleranced data, default tolerances, ISO 10110, optical drawings, drawing indications, fabrication defaults, inspection defaults.
