ASTM D4541 pull-off test (for wood or steel substrates) and ASTM D7234 (concrete pull-off test) will always be more reliable. Cross-cut tests (tape adhesion) are just a simple checking test

Generally it depends on the test area and the number of panels you have. It's different to how you prepare panels in the laboratory, different to how you have to perform a test on an element whose surface is limited, e.g. on a construction site or on panels after SST. It also depends on whether you have a good result, an evidently bad result or a moderate failure of the cross-cuts. If the result is clearly bad (100% failure) or clearly good (0% failure), it is enough to do 2-3 repetitions. If you have an intermediate result, you should do 5-8, and sometimes even 10 repetitions for adequate repeatability and precision.
the music slaps. also, thank you for the clear video with reference to the ASTM spec
whats the song name?
This is some track from the YT library, but I can't find what it was. Search the library in YT studio in the electronic music category.
My pleasure.
Is this test method for testing adhesion to metal substrates only? Or is it also used on plastics and wood composites and such?
You can use cross-cut test method for many hard and rigid substrates, not only metal.
ASTM 3359 VS ASTM D4541: which test method is a better for testing exterior painting? Which is a more accurate measurement for the pull out strength?

Very Good !
Thank you!
Thanks for the video. Could you mention the exact type of the multi-edge cutting knives you are using? Thank you!
Thank you for your comment.
We use TQC Sheen knifes, both ASTM (straight edge) and ISO (wheel). Please find on TQC Sheen website

For sure! :D We are already negotiating participation in the future Oscars ;)
how many trials that will give you more accurate result?

Can I apply this metohd for flexible film?
Generally the method is to use it on a substrate that needs to be fairly stiff, but you'll have to try it to be sure.
Cutter name please and available who
All equipment is ASTM compliant. It's important to use standardized types of cutters.
Method A is Xcut while the cross cut is method B
Just like in the video
The music is terrible
The tastes could be discussed endlessly, but we hope that at least you liked the content of the film :)
@@SpektrochemResearchLaboratory i loved the music choice more than the video haha. very informative video. thank you
@@mohammedalbloushi4735 Thanks! :)))
