Overview

ISO 10242-3:2008 is an international standard developed by the International Organization for Standardization (ISO) that defines the specifications for punch holder shanks, specifically Type D, used in press tooling applications. This standard ensures the interchangeability of punch holder shanks by specifying critical dimensions, tolerances, and hardness requirements. As part of the broader ISO 10242 series, it plays a crucial role in unifying tooling components for manufacturing and metal pressing industries, promoting compatibility and quality.

Key Topics

Interchangeability Dimensions and Tolerances:
ISO 10242-3:2008 precisely defines the geometric dimensions and tolerances of Type D punch holder shanks-measured in millimetres-to guarantee that components fit seamlessly across different press tools. The standard includes detailed diagrams and tables for dimensions such as body diameter, thread pitch, and length.

Material Guidance and Hardness Requirements:
While the selection of material is at the manufacturer’s discretion, the standard mandates a minimum hardness of 140 HB (Brinell hardness). This hardness level ensures durability and longevity of the punch holder shanks under repeated mechanical stress during pressing operations.

Designation System:
The standard provides a clear system for designating Type D punch holder shanks, incorporating:

• The generic term "Punch holder shank"
• Reference to ISO 10242-3
• The specific type (D)
• The body diameter (D1) in millimeters
• The nominal thread diameter (D3)
  This designation aids in straightforward identification and communication across suppliers, manufacturers, and maintenance teams.

Surface Texture Specifications:
Updated to align with ISO 1302:2002, ISO 10242-3:2008 specifies surface roughness values in micrometres to ensure appropriate surface finish and performance in tooling environments.

Applications

ISO 10242-3:2008 is essential for manufacturers, engineers, and quality control specialists involved in tooling and press operations, particularly where punch holder shanks are a critical component. Typical applications include:

• Sheet metal forming and pressing tools
• Die and mold manufacturing
• Industrial press assemblies requiring standardized tool components
• Maintenance and replacement services ensuring component compatibility
• Quality assurance for tooling suppliers to meet international standards

By adhering to ISO 10242-3, companies can reduce tooling errors, improve interchangeability, and optimize production workflows in metal pressing environments.

Related Standards

ISO 10242-3:2008 is part of a series focused on punch holder shanks, which includes:

• ISO 10242-1: Punch holder shanks - Type A
• ISO 10242-2: Punch holder shanks - Type C

Additionally, it references other important standards relevant for compliance and quality:

• ISO 6506: Metallic materials - Brinell hardness test, which defines testing methods for material hardness
• ISO 1302:2002: Geometrical Product Specifications (GPS) - Indication of surface texture in technical product documentation, critical for surface roughness specifications

These related standards collectively support manufacturing precision and global interoperability of press tooling components.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of th

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
