ISO Publishes DMSC Metrology Standard

The new standard, known as ISO 23952:2020, describes the general content and structure of the Quality Information Framework (QIF) information model.

The ANSI/DMSC QIF 3.0 metrology standard from Digital Metrology Standards Consortium (DMSC) was recently harvested, approved, and published by ISO as the new ISO Standard ISO 23952:2020.

DMSC is the developer and maintainer of Quality Information Framework (QIF) and other metrology standards. These standards are intended to help advanced manufacturers reduce costs and offer a common format for product measurement results. They are also a critical enabler for digital transformation via Model Based Enterprise (MBE).

The new standard, available directly from ISO, is officially titled “Automation systems and integration — Quality information framework (QIF) — An integrated model for manufacturing quality information.” The 498-page document describes the general content and structure of the entire QIF information model. It documents the highest level data structures of QIF using data dictionaries and XML schema files. The standard seamlessly defines, organizes, and associates quality information including measurement plans, resources, part geometry with product and manufacturing information (PMI), rule templates for measurement, results, and statistical analysis.

QIF 3.0 was accepted as an American National Standards Institute (ANSI) standard in 2018, then submitted for ISO “harvesting” by technical committee ISO/TC 184/SC 4 in early 2019 before it was approved and officially published by ISO in July.

“We are extremely pleased to have attained a DMSC goal of having the ANSI/DMSC QIF v3.0 standard become recognized and published as an ISO standard,” says Curtis Brown, president of DMSC. “Navigating the ISO approval process has been insightful and challenging, with the reward that the ISO community is now able to offer ISO 23952 as an integrated model for manufacturing quality information.”

DMSC will continue to improve and enhance digital information standards such as the QIF, and the organization’s membership is in the process of refreshing its roadmap to broaden its development focus on technologies that will further support digitization, connecting the digital thread and supporting model-based enterprise.


  • Raising the Bar with Ballbar Testing

    Few manufacturing companies rely on ballbar testing to maintain machine tool accuracy as thoroughly as Silfex. Now, advanced training and a move to a Renishaw QC20-W wireless system have enabled the company to take the benefits of ballbar testing to a higher level.

    Here are some of the tools and techniques for making sure machine tools stay at peak performance levels.

  • Measuring Part Geometry On The Shop Floor

    Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
