ISO 2145:1978-Documentation

What is ISO 2145:1978-Documentation -Numbering of divisions and subdivisions in written documents?

ISO 2145:1978-Documentation standard that outlines the rules for numbering the various sections and subsections in written documents. This standard aims to establish a uniform and systematic approach to the numbering of divisions and subdivisions in documents, which can include but are not limited to, technical papers, reports, and manuals.

The standard specifies how to number the primary, secondary, and further divisions of a document. For example, the primary divisions might be numbered as 1, 2, 3, etc., while the subdivisions under the first primary division would be numbered as 1.1, 1.2, 1.3, and so on. This hierarchical numbering system allows for easy navigation and reference within the document.

Furthermore, the importance of a standardized numbering system cannot be overstated, especially in contexts where precision and clarity are paramount. For instance, in the realm of management system certifications such as ISO 9001 or ISO 14001, a well-structured document with clearly numbered sections can facilitate easier understanding and implementation of quality management or environmental management systems. This can be particularly beneficial for certification bodies like Pacific Certifications, as it ensures that the documents you assess or produce are easily navigable and interpretable, thereby reducing the likelihood of misunderstandings or errors.

The ISO 2145:1978 standard is not just a set of arbitrary rules; it is based on the collective wisdom and best practices that have evolved over time. By adhering to this standard, organizations can ensure that their documents are organized in a manner that is universally understood, thereby enhancing their credibility and the ease with which their documents can be used for reference or implementation.

What are the requirements for ISO 2145:1978-Documentation?

ISO 2145:1978 sets forth specific guidelines for the numbering of divisions and subdivisions in written documents to ensure a consistent and systematic approach. While the standard itself would provide the most comprehensive and authoritative information, the general requirements can be summarized as follows:

Hierarchical Numbering

The standard mandates a hierarchical numbering system for the divisions and subdivisions of a document. This means that each level of the document’s structure is represented by a series of numbers separated by periods.

  • Primary Divisions: Numbered as 1, 2, 3, etc.
  • Secondary Divisions: Numbered as 1.1, 1.2, 1.3, etc., under the first primary division, and similarly for other primary divisions.
  • Tertiary Divisions: Numbered as 1.1.1, 1.1.2, 1.1.3, etc., under the first secondary division, and so on.


The numbering should be consistent throughout the document. If a certain level of division is numbered, all divisions at that same level should also be numbered.

No Leading Zeros

The standard specifies that leading zeros should not be used. For example, it should be “1” instead of “01.”

No Alphabetic Characters

Only Arabic numerals should be used for numbering, and alphabetic characters should be avoided unless the document specifies otherwise.

Punctuation and Formatting

The standard may also provide guidelines on the use of punctuation marks, such as periods or colons, and the formatting of the numbers, although this can vary depending on the specific requirements of the document or the organization.


The numbering should be continuous and should not skip any numbers. For example, if a section is removed, the subsequent sections should not retain the old numbering but should be renumbered to maintain continuity.

The adherence to ISO 2145:1978 can be particularly beneficial for organizations involved in issuing or assessing management system certifications, such as Pacific Certifications. For example, when evaluating a company’s compliance with ISO 9001 or ISO 14001, a well-structured, clearly numbered document can significantly streamline the audit process. It allows auditors to easily locate specific clauses or requirements, thereby enhancing the efficiency and effectiveness of the certification process.

In summary, ISO 2145:1978 aims to standardize the numbering of divisions and subdivisions in written documents to facilitate easier navigation, better organization, and enhanced readability. By adhering to this standard, organizations can ensure that their documents meet universally accepted best practices.

What are the benefits of ISO 2145:1978?

The adoption of ISO 2145:1978, which standardizes the numbering of divisions and subdivisions in written documents, offers several benefits that can be particularly advantageous for various stakeholders, including organizations, certification bodies, and end-users. Here are some of the key benefits:

Enhanced Readability and Navigation

A standardized numbering system makes it easier for readers to navigate through a document. This is particularly useful in lengthy or complex documents where quick reference to specific sections is often required.

Improved Consistency

The standard ensures that all documents follow a consistent numbering format. This uniformity is crucial when multiple documents are part of a larger system or suite, as it aids in cross-referencing and reduces the likelihood of errors or misunderstandings.

Facilitates Collaboration and Communication

When everyone is on the same page regarding how document sections are numbered, it simplifies collaboration and communication. Team members can easily refer to specific sections during discussions, making the communication more efficient and less prone to misunderstandings.

Easier Document Maintenance

A standardized numbering system makes it easier to update documents. When changes are made to one section, the standardized numbering helps in quickly identifying which other sections might be affected and need updating.

Streamlined Auditing and Compliance Checks

For certification bodies like Pacific Certifications, which are involved in issuing various management system certifications, a standardized numbering system can significantly streamline the auditing process. Auditors can easily refer to specific sections when checking for compliance, making the process more efficient.

Global Recognition and Credibility

Adhering to an internationally recognized standard like ISO 2145:1978 lends credibility to the document and, by extension, to the organization that produced it. This can be particularly beneficial in international settings where documents may be shared across different countries and cultures.

Facilitates Digital Search and Automation

In the digital age, a standardized numbering system can facilitate the searchability of documents. Automated systems can more easily identify and retrieve specific sections, thereby enhancing the utility of document management systems.

Risk Mitigation

A well-structured document reduces the risk of misinterpretation or errors, which can be particularly critical in legal, scientific, or technical documents where even a small error can have significant implications.

In summary, the benefits of ISO 2145:1978 extend beyond mere aesthetics or formatting preferences. The standard serves as a tool for enhancing the quality, utility, and credibility of written documents. Its adoption can lead to more effective communication, easier document management, and a more streamlined process for auditing and compliance checks.
