If you want to obtain ISO standards legally but for a price significantly lower than ISO, the answer is simple. Buy them from EVS, the Estonian Centre for Standardisation and Accreditation[1].
They have a nice English website, and you don't have to have any ties whatsoever to Eestonia, or Europe.
The customer service people speak perfect English too if you have any questions.
EN just means the regionally adopted version of the standard. For all intensive purposes EN and ISO are typically identical[1][2]. EN is ISO with additional Z Annexes as applicable.

DIN EN 13850 was "Postal service - Quality of service - Measurement of the transit time of end-to-end services for single piece priority mail and first class mail", but it has been rescinded.
DIN EN ISO 13850 is "Safety of machinery - Emergency stop function - Principles for design"
"intents and purposes"?
