ISO 14617: A Comprehensive Guide to Piping and Pipelines
ISO 14617 is a standard for " Petroleum, petrochemical and natural gas industries - Drilling and production equipment".
Conclusion: Don't Get Sued Over a Symbol
Yes. The standard is a specification , not a patent. You are free to draw the symbols yourself and include them in your app. You just cannot copy-paste ISO's official explanatory text without a license.
If you are a professor, you can request a "teaching copy" or evaluation copy directly from your local ISO member body. They often provide watermarked PDFs for classroom use at no cost, provided you do not distribute them publicly.
ISO 14617 is not a single standard you can download as a simple PDF.
A "proper piece" on this subject must first address a common misconception: It is actually a series of standards (consisting of over 15 separate parts) that have largely been incorporated into the broader IEC 81346 series.
The standard is divided into several parts, each focusing on specific technical domains or functional groups:
- Example: Visit the BSI (British Standards Institution) reading room in London or the AFNOR library in Paris.
- Cost: Free on-site reading; printing costs apply.
