DIN tolerances for fine spur gear of module < 1 mm?

[sabaa]

Hi everybody,
As you know, DIN 3961 gives tolerances for gear of module>=1. It refers to DIN 58405 for fine gears of module<1. But, as I know, DIN 58405 has been withdrawn!! So:
1-For fine gear of module < 1; which DIN standard is applicable?
2-For gear of module>=1, both DIN 58405 and DIN 3961 are specifying tolerances. Which one is applicable in this case?
Thank you in advance

Looks like no DIN standard for m<1 is currently applicable. For m>=1 DIN 3961 should be used.
