The question came up in my consulting practice the other day:
"Martin, if our bike passes ISO 4210, will we be exempt from liability?"
Short answer: Unfortunately not.
ISO standards are - except in France - only recommendations under private law. They are not laws and therefore have no direct effect on liability issues.
If your bike passes the ISO tests, this is of course a strong sign of quality.

My tip: ISO tests are important, but only one part of your protective shield. Safety and care must always be considered holistically.
If you want to know more about how to cleverly reduce liability risks - I'm just a message away.
