According to the European Standard EN 12150-2:2004, to establish whether a product conforms to the definition of thermally toughened soda lime silicate safety glass, initial type testing shall consist of a) mechanical strength measurement in accordance with EN 12150-1 (also EN 1288-3:2000) and/or b) fragmentation test
in accordance with EN 12150-1:2000.
Sperm DNA fragmentation test
is done in some countries but there are still varied opinions on its efficacy and it's not being done in India.
Among specific topics are the thermal effects of cracked piezoelectric materials under cycling electric-loading, the reliability of the fragmentation test
, fracture behaviors of nano-silica modified epoxies at elevated temperature, interfacial toughness in a synthetic bone-cement interface, and micro-cracking in nanocrystalline silicon due to indentation and scratching.
SCSA test (also known as sperm DNA fragmentation test
or sperm chromatin fragmentation test
) is original and gold standard for sperm DNA fragmentation screening which delivers a highly accurate measure of male reproductive health (24).
Thus European standards prescribe application of the four-point bending test and the fragmentation test.
This paper gives a brief description of the portable polariscope SCALP and some measurement results, which are compared with the four-point bending test and fragmentation test.
At another glass factory, 7 panels of different kind of glasses but of the same thermal treatment were investigated, first measuring the surface stress and after that making the fragmentation test according to EN 12150-1:2000.
Thus the fragmentation test results can be used only as a rough indicator of the fact that the glass panel has been thermally treated.
Plywood devices that represent vehicle occupants are used for fragmentation tests
