Telling the difference between UV92 and uv70

[BeatnikFraming]

Just wondering if there's a way to tell the difference between truview uv70 & UV92. I ordered a piece of UV92 cut to size and while it's invoiced and written on the packet as UV92 it's come with uv70 stickers loose inside the pack. I will ring wessex on Monday but just thought I'd ask if there's way to tell what I actually have

They used to be different colours when you looked at the reflection from a light i think if it was green it was the lower uv and if its purple its the higher maybe the other way around sorry this is from memory,

Very good question!

I buy them by the box and put the un-used pieces back into the same box. Not very imaginative, but it saves needing to be brainy enough to tell which is which. Anything to make life easier suits me!

Thanks Theframer, this seems to have done the trick. I have a piece framed in uv 70 and comparing the reflections there was a difference, the uv70 was more of a green reflection and what I ordered as UV92 has a more blue/purple reflection. So I think I'm safe to assume that they've just put the wrong stickers in
