At the top of the CR4 page is a button labeled "Standards Library". You can find nearly all public domain standards there for free. The standards not part of the public domain can be found there too but for the mandatory fee.
Depending on how well you can clearly identify the relevant standard you seek this might take some sleuthing. There is a myriad of DIN standards.
Good Luck
