Help finding a section of IEC 60268-21?

I have no idea where else to post this so...

Do any of you guys happen to have a copy of IEC 60268-21? I need to understand the portion on max SPL testing (I believe this is Chapter 16.2) but I can't swing the $350 to purchase it. If someone can help me out, it would be appreciated. Feel free to email me directly at hardisj at gmail dot com.

Thanks,
Erin
