Tsananguro pfupi:

Iyi tester yekunamatira yakagadzirwa kuti iongorore simba rekunamatira kwe organic coatings ichishandisa nzira yakajairwa yegrid/cross-cut. Inoita lattice pattern incision chaiyo kuburikidza ne coatment kuenda ku substrate, zvichibvumira kuongororwa kwe resistance ye coatment yekuparadzaniswa zvichienderana ne classification scale ye grade-grade six. Yakakodzera bvunzo dze laboratory nedze pafield, inoenderana nezvinodiwa zve standards zvakaita se GB/T 9286-1998 uye GB/T 4893.4.
