ISO 16792 PDF

His work increased production of naval weapons by new contractors. In , Parker published Notes on Design and Inspection of Mass Production Engineering Work, the earliest work on geometric dimensioning and tolerancing. The datum reference frame can describe how the part fits or functions. There are some fundamental rules that need to be applied these can be found on page 7 of the edition of the standard : All dimensions must have a tolerance. Every feature on every manufactured part is subject to variation, therefore, the limits of allowable variation must be specified.

Understandably, we may not be an expert in every standard published by ISO the International Organization for Standardization , particularly with respect to technical product documentation ISO For the sake of clarity, ISO standards often reference one another, but in the real world of global manufacturing, integrating these standards into a sound quality management system remains challenging.

More articles on ISO Given the importance of digital product-definition data, it is no wonder why technical standards, such as ISO , are such a hot topic as moves forward. It is not uncommon for seasoned quality managers to misconstrue standards occasionally, so what is ISO ? This post gives us a refresh on this critical standard for digital product-definition data practices.

Why create ISO ? Originally published in , ISO has guided digital product-definition data practices since the modern era of three-dimensional 3-D , computer-aided design CAD gained momentum over 10 years ago. We may recall that during this time period, far too many organizations used their CAD systems as little more than high-tech, electronic drawing boards. A standardized format and rules governing digital product-definition data were not yet required of CAD software vendors and manufacturers alike.

In essence, manufacturers were working with a disjointed, disparate set of proprietary solutions, a patchwork of software to document product specifications, tolerances, dimensions and annotations. There were plenty of opportunities for errors and inconsistencies to occur when designating data formats on traditional, two-dimensional 2-D drawings and 3-D models with myriad default configurations for embedded data.

As such, several questions arose during this time. Which data should we include in a traditional two-dimensional 2-D drawing? Which data should we include or omit in a 3-D model or partial model? What is in ISO ? ISO defines how to structure data and establishes digital product-definition data practices for both drawings and 3-D models, either separately or in conjunction with one another.

The overall goal of the standard is to foster consistent product-definition data practices and lay the groundwork for further technological developments.

ISO establishes two ways to apply the standard, depending on the manufacturing and design context. The standard provides guidance for product-definition data in 3-D models exclusively or for models and 2-D drawings together. Within the standard, we can find more information on which practices are applicable to which method. Thus, ISO remains one of the most critical yet lesser-known standards published by ISO over the last 10 years. What is next for ISO ? Over the next few years, we can expect ISO to update this standard to accommodate emerging technologies.

When product-definition data practices shift, our quality management system has to be able to pivot likewise and remain compliant at an acceptable cost. One way to prepare ourselves to adapt is to have enterprise quality management software EQMS in place. Document control is a notoriously difficult endeavor for many reasons other than the requirements of ISO EQMS enables us to manage quality from an enterprise perspective, without the problem of data silos and disparate software solutions impeding our work at every step.

EQMS breaks down the walls separating enterprise data to allow us to manage quality from a holistic context.

Even seasoned quality managers misconstrue standards from time to time. ISO remains one of the lesser-known yet absolutely critical standards that have been in practice for quite some time.
