How to write a digital-ready standard
Downloaded from SAE International by SAE International [Sales Team], Tuesday, October 25, 2022
By LESLIE MCKAY, senior
product manager specialist,
SAE International.
As the world moves from analog
to digital, engineering resources
need to be accessed in a digital
format. This drive for digitization
promotes interoperability
between different systems to
help drive efficiencies and
development of complex
products. While the industry
hopes to get to a point where a
single tool can be used to author
both a digital standard and a
PDF natively, we are not there
yet. In the interim, SAE is using
AI models to read and convert
PDF standards into a true digital
format.
Over the past year or two, SAE
has digitized over 1500 parts and
materials standards into a
database format. Throughout
this process, SAE has learned a
lot of lessons and helpful hints
about how to structure tables,
content, etc. to make it easier for
AI models to be used to digitize
a standard.

NOTES:
1. Hardness shall not be the basis for rejection if tensile properties are acceptable, determined on specimens taken from the same sample as
that with nonconforming hardness or from another sample with similar nonconforming hardness.
2. For sizes over 3 inches (76 mm), 35% for H900 condition and 38% for H925 condition.
3. Temperature tolerance ±10 °F (±6 °C); time tolerance ±0.1 hour (±5 minutes); cool in air.
4. Temperature tolerance ±10 °F (±6 °C); time tolerance ±0.3 hour (±15 minutes); cool in air.
5. Maximum; alternate for wire: 175 ksi (1207 MPa) or equivalent hardness (see 8.3).
6. Temperature tolerance ±25 °F (±14 °C); time commensurate with thickness, heating equipment, and procedure used, and cooling as required
to below 90 °F (32 °C).
3.4.3.2.2 Alternative Test of Forging Stock
Example of a poorly thought-out table.
A sample of stock, forged to a coupon having a percent reduction not greater than the least reduced portion of the forging
and heat treated in accordance with 3.3 and Table 2 shall conform to the requirements of Table 2.
3.5 Quality
tables and figures in your requirements?
* How to best organize data tables for digital
conversion?
The product, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and
from imperfections detrimental to usage of the product.
3.5.1 Grain flow of die forgings, except in areas which contain flash-line end grain, shall follow the general contour of the
forgings showing no evidence of reentrant grain flow.
* How to set up your data so that customers can
search across multiple digital standards on
properties, elemental composition, etc.?
* The importance of consistency to minimize the
complexity of your AI models?
3.7 Production, distribution, and procurement of metal stock shall comply with AS6279. After production and certification
to the specified requirements, cutting in a plane perpendicular to the short transverse dimension is permitted. The
requirement for compliance with AS6279 becomes effective 04/01/2019.
SAE has gathered information together to create
awareness and educate others on how to write a
digital-ready standard. The information is organized
to consider:
Document structure: Standards authors need to
understand how to best organize titles, subtitles, and
content and how to reference figures and tables.
Table structure: Humans and machines " think "
differently. A table that can be read and interpreted
by a human may not be so easily understood by a
machine. As a result, this section looks in detail at
table structure, the organization of rows versus
UPDATE
3.6 Tolerances
Shall conform to all applicable requirements of the following:
3.6.1 Bars and Wire
In accordance with AMS2241.
3.6.2 Mechanical Tubing
In accordance with AMS2243.
