How to Download the ISO 14405 E Standard for Geometrical Product Specifications
If you are involved in designing, manufacturing, or verifying products that require dimensional tolerancing, you may need to refer to the ISO 14405 E standard. This standard establishes the default specification operator for linear size and defines a number of special specification operators for linear size for features of size, such as cylinders, spheres, tori, circles, or two parallel opposite planes or straight lines[^3^].
The ISO 14405 E standard is part of the ISO Geometrical Product Specifications (GPS) system, which provides a set of rules and concepts for expressing and interpreting geometrical specifications on technical drawings. The ISO GPS system consists of a number of standards that cover different aspects of geometrical tolerancing, such as form, orientation, location, run-out, and profile[^4^].
The ISO 14405 E standard is divided into two parts: Part 1 covers linear sizes and Part 2 covers dimensions other than linear or angular sizes. Part 1 was published in 2016 and Part 2 was published in 2018. Both parts are available for purchase from the ISO website or from your national standards body. However, if you want to get a free PDF download of the ISO 14405 E standard, you may have some options depending on your situation.
Option 1: Check if you have access to a subscription service
Some organizations or institutions may have access to subscription services that provide online access to a large collection of standards, including the ISO 14405 E standard. For example, some universities or libraries may have subscriptions to services like IEEE Xplore, SAI Global, or Techstreet. If you are affiliated with such an organization or institution, you may be able to download the ISO 14405 E standard for free by logging in to the subscription service with your credentials.
Option 2: Check if you can borrow a copy from a library
Another option is to check if your local library has a physical or digital copy of the ISO 14405 E standard that you can borrow. Some libraries may have print copies of standards that you can check out or photocopy. Others may have digital copies that you can access through their online catalog or e-book platform. You can search for the ISO 14405 E standard by its title or reference number on your library's website or ask a librarian for assistance.
Option 3: Check if you can find a free preview online
A third option is to check if you can find a free preview of the ISO 14405 E standard online. Some websites may offer a limited preview of the standard's content, such as the table of contents, foreword, introduction, or scope. For example, you can find a free preview of Part 1 of the ISO 14405 E standard on the ISO Online Browsing Platform[^1^]. However, be aware that these previews are not complete and may not contain all the information you need.
The ISO 14405 E standard is an important document for anyone who deals with geometrical product specifications and dimensional tolerancing. It defines how to specify and interpret linear sizes and other dimensions on technical drawings. The standard is available for purchase from the ISO website or from your national standards body. However, if you want to download it for free, you may have some options depending on your situation. You can check if you have access to a subscription service, borrow a copy from a library, or find a free preview online. c481cea774
