Galvenie test\u0113\u0161anas standarti<\/h2>\n\n\n\n

The NF T54-116<\/strong> standarts nosaka test\u0113\u0161anas metodi, ar kuru nosaka pl\u0113ves triecieniztur\u012bba<\/strong> m\u0113rot ener\u0123iju, kas nepiecie\u0161ama plastmasas loksnes caurdur\u0161anai, izmantojot sv\u0101rsta roku, kas apr\u012bkota ar puslodes formas trieciena galvu. Tas ir sal\u012bdzin\u0101ms ar pasaul\u0113 atz\u012btu ASTM D3420<\/strong> standarts, kas nov\u0113rt\u0113 plastmasas pl\u0113ves triecieniztur\u012bba pret sv\u0101rsta triecienu<\/strong> izmantojot l\u012bdz\u012bgus principus. Port\u0101ls Spencera triecientests<\/strong> ir v\u0113l viena saist\u012bt\u0101 metode, ko pla\u0161i izmanto Zieme\u013camerik\u0101 un kas kalpo par etalonu Spencer trieciena test\u0113\u0161anas iek\u0101rtas<\/strong>.<\/p>\n\n\n\n
