ISO 1119:2011 provides calculated values for a series of cones or conical tapers, ranging from 120° to less than 1°, or ratios from 1:0,289 to 1:500, intended for general use in technical engineering. It applies only to plain conical surfaces, and excludes prismatic pieces, taper threads, bevel gears, etc.

Overview

EN ISO 1119:2011 (ISO 1119:2011) is a Geometrical Product Specification (GPS) standard that defines a standardized series of conical tapers and taper angles for general engineering use. It provides calculated values for a series of cones or conical tapers with cone angles from 120° down to less than 1° (equivalently taper ratios from ≈1:0.289 to 1:500). The standard applies only to plain conical surfaces and explicitly excludes prismatic pieces, taper threads, bevel gears and similar non‑plain conical forms. EN ISO 1119:2011 was prepared by ISO/TC 213 and adopted by CEN.

Key topics and technical requirements

Scope and applicability: Values cover cones intended for general technical engineering; only plain conical surfaces are in scope.

Series and tables: Two primary series (Series 1 and Series 2) are defined.

Table 1: Recommended cones for general applications - lists cone angle (degrees/minutes/seconds), radians, rate of taper and initial/preferred values.
Table 2: Selection of cones for particular applications (e.g., machine-tool tapers, drill-chuck tapers, Morse and Jacobs tapers, medical connectors) - use only for the indicated applications.

Dimensioning and tolerancing: Cones shall be dimensioned and toleranced in accordance with ISO 3040.

Design intent: Series 1 and 2 initial values are ordered to reduce the variety of tools, gauges and measuring instruments required in production.

Informative notes: Values are provided as calculated information; Series 1 values align approximately with preferred number series (ISO 3, R10/2 and R10/3).

GPS context: The standard is a general GPS document and relates to the GPS matrix model (see Annex A); it follows overarching GPS rules such as ISO 8015 and decision rules like ISO 14253‑1.

Applications and who uses it

EN ISO 1119:2011 is used where consistent specification of cone geometry streamlines design, manufacture and inspection:

Mechanical and design engineers specifying tapers for shafts, housings and fittings

Toolmakers and machine-tool designers (spindles, tool shanks, tapers)

Quality engineers and metrology labs verifying conical surfaces

Manufacturers of medical connectors (e.g., Luer/conical fittings), textile machinery cones, and rotating machinery components

Standards committees and technical authors referencing GPS conventions

ISO 3 - Preferred numbers

ISO/IEC standards cited in Table 2 (e.g., ISO 296, ISO 239, ISO 5356‑1)

Using EN ISO 1119:2011 helps ensure consistent specification of taper angles and rates of taper across design, production and inspection processes, reducing tooling diversity and improving interoperability in engineering components.
