Full title and description

Geometrical product specifications (GPS) — Dimensioning and tolerancing — Cones. ISO 3040:2016 specifies the graphical indication (symbols and annotation) used to define the dimensioning and tolerancing of right‑angle circular cones (illustrated using truncated cones but applicable to cones within the defined scope).

Abstract

ISO 3040:2016 establishes the graphical symbol(s) and rules for indicating cones on technical product documentation so that their size, form and tolerance requirements are clearly and unambiguously communicated. The standard focuses on right‑angle circular cones and shows how to dimension and tolerate cones on drawings and related documentation, while not precluding other acceptable methods of indication.

Key bibliographic and lifecycle metadata (edition, page count, committee and confirmation status) are reported in the ISO bibliographic record for ISO 3040:2016. The 2016 edition replaced the earlier 2009 version and was reviewed/confirmed in a subsequent 5‑year review cycle.

Scope

Specifies the graphical indication applicable to cones — specifically right‑angle circular cones (any cross‑section perpendicular to the axis is a circle). For simplicity the standard illustrates truncated cones but the rules apply to cones within the defined scope. The standard provides the symbols and rules needed to indicate cone dimensions and tolerance specifications on technical drawings and related documentation. It is not intended to prohibit other valid methods of indication where appropriate.

Key topics and requirements

• Graphical symbols and annotation conventions for representing right‑angle circular cones on technical drawings.
• Rules for indicating cone dimensions (apex/axis references, diameters at given sections, cone angles and lengths) and acceptable truncated‑cone representations.
• Guidance on specifying tolerances relevant to cone features within the GPS framework.
• Clarification of applicability (right‑angle circular cones) and note on alternative methods — the standard does not prevent other suitable dimensioning/tolerancing methods.
• Alignment with ISO GPS family practices and referencing of related GPS principles and notation.

Typical use and users

Used by mechanical designers, draughtspeople, engineering drawing specialists, CAD modelers, manufacturing engineers, quality and metrology personnel, and standards librarians who prepare, interpret or verify technical product documentation. Typical applications include component drawings for turning/lathe operations, tapered fits, tooling elements, gages and any engineering part where conical features must be dimensioned and tolerance‑controlled. The standard helps ensure consistent interpretation between designers, manufacturers and inspectors.

Related standards

ISO 3040 is part of the ISO GPS family and should be used in conjunction with broader GPS and technical drawing standards such as ISO 1101 (geometrical tolerancing and symbol language), ISO 129‑1 / EN ISO 129 (presentation of dimensions and tolerances / dimensioning principles), ISO 8015 (fundamental tolerancing principle) and other GPS standards covering datums, verification and specific tolerance rules (for example ISO 5459 on datums and datum systems). These related documents provide the foundational rules and complementary guidance for general dimensioning, datum definition and interpretation of geometrical tolerances.

FAQ

Q: What is this standard?

A: ISO 3040:2016 is an ISO International Standard that defines the graphical symbols and rules for dimensioning and tolerancing right‑angle circular cones on technical product documentation.

Q: What does it cover?

A: It covers the graphical indication applicable to cones (illustrated with truncated cones) to define cone dimensions and specify tolerancing on drawings; it is focused on right‑angle circular cones and provides notation rules while allowing other suitable methods where appropriate.

Q: Who typically uses it?

A: Mechanical designers, CAD/drawing specialists, manufacturing and inspection engineers, metrologists and anyone responsible for producing or interpreting engineering drawings that include conical features.

Q: Is it current or superseded?

A: The current edition is ISO 3040:2016 (Edition 4, published 2016). This edition replaced earlier editions (for example the 2009 version) and was reviewed/confirmed in subsequent ISO review cycles. Users should check national adoption or later revision notices before assuming changes.

Q: Is it part of a series?

A: Yes — ISO 3040 is part of the Geometrical Product Specifications (GPS) family and is intended to be used together with other GPS and technical drawing standards (for example ISO 1101, ISO 129‑1, ISO 8015, ISO 5459 and related documents) to provide a complete and consistent approach to dimensioning and tolerancing.

Q: What are the key keywords?
