Sigh, I searched online all morning without finding it. These two standards aren’t new at all; they’re from such an old era – why isn’t there any information about them online?
I’ll go check other forums; I hope to find it there.
I’m not sure if you’ve received the text message with the \"positive result\"; if you’re not satisfied with what you got, feel free to ask more questions. I’m sure there will be someone willing to help. Good luck! It’s such an old item; it’s really difficult to find an electronic version of it. Please understand!
