Boleng ba tšepe ea sebopeho sa s355 bo molemo ho feta tšepe s235 le S275 ho hlahisa matla le matla a mashome a matla.
Tšebelisano ea Stere S355 Nama (lebitso)
Mangolong le linomoro tse latelang li hlalosa moelelo oa S355.
"S" e khuts'oane ho "tšepe ea sebopeho".
"355" e bua ka 'mele oa ho hlahisa boleng ba matla le botenya ba tšepe e telele le e telele ea tšepe ≤ 16mm.
"Jr" e bolela boleng ba matla a tšusumetso e nyane 27 J ka mocheso oa kamore (20 ℃).
"J0" e khona ho mamella tšusumetso e matla bonyane 27 J A ho 0 ℃.
"J2" e amanang le boleng ba 'mele ea ho senya boleng ke 27 J At -20 ℃.
"K2" e bua ka tšusumetso ea 'mele ea matla ke 40 J At -20 ℃.
