Overview

The EN ISO 14405-2:2011/prA1 standard, titled Geometrical Product Specifications (GPS) - Dimensional Tolerancing - Part 2: Dimensions other than linear sizes - Amendment 1 (ISO 14405-2:2011/DAM 1:2017), is a key document in the field of geometrical product specifications. Published by CEN and aligned with ISO standards, it focuses on dimensional tolerancing principles for geometric dimensions except linear and angular sizes. Although this particular work item (WI) was abandoned following the cancellation of the equivalent ISO WI in 2018, the amendment clarifies critical aspects of GPS related to non-linear and non-angular tolerancing.

The standard forms part of the overarching GPS framework and guides users on avoiding ambiguity in tolerancing dimensions other than straightforward linear or angular values. It acts as a critical reference for professionals seeking to utilize geometrical tolerancing methods to improve specification clarity and precision across a variety of manufacturing and engineering applications.

Key Topics

• Scope and Purpose
  EN ISO 14405-2/prA1 addresses the use of geometrical tolerancing for dimensions excluding linear or angular sizes. It highlights risks of ambiguity introduced by traditional ± tolerances when applied outside the domain of linear and angular dimensions.

• Geometrical Tolerancing to Eliminate Ambiguity
  The amendment stresses the importance of using geometrical tolerances to minimize specification ambiguities that arise with ± tolerances, particularly for complex shapes or features where linear or angular tolerances are insufficient or misleading.

• Alignment with GPS Matrix and Other Standards
  This standard is aligned with the GPS matrix model described in ISO 14638 and follows foundational GPS principles from ISO 8015. It also references practical tolerancing approaches found in companion standards such as:

  • ISO 14405-1 for linear sizes
  • ISO 14405-3 for angular sizes
  • ISO 2538 series for wedges
  • ISO 3040 for cones

• Normative References and Updates
  The document updates and replaces earlier references to ISO standards, reflecting current practices and aligning with revised norms for technical drawings, dimensional tolerancing, and geometrical verification.

• Examples and Practical Guidance
  Included are examples demonstrating geometrical tolerancing applied to angular distances between integral and derived features, showcasing how the amendment addresses common design and manufacturing challenges.

---

Applications

• Precision Engineering and Manufacturing
  EN ISO 14405-2/prA1 facilitates clear and unambiguous specifications in precision parts where dimensions other than linear or angular sizes are critical, improving manufacturing accuracy and interoperability.

• Technical Drawing and Product Documentation
  The standard guides technical drafters and engineers in indicating tolerances on drawings, helping avoid errors related to improper use of ± tolerances on complex geometric features.

• Quality Assurance and Inspection
  By promoting geometrical tolerancing methods for non-linear dimensions, the standard supports enhanced inspection protocols and quality control in production environments.

• Product Design and Development
  Designers benefit from reduced specification ambiguity, leading to better communication of functional requirements and tighter control over product dimensions that are essential for fit, function, and performance.
