⑤ Amanqaku okanye imida: Ubungakanani besampuli: Isampuli enkulu iyadingeka ukuze kuqinisekiswe ukuba i-indentation inkulu ngokwaneleyo kwaye ichanekile, kwaye umphezulu wesampuli kufuneka ube flat kwaye ucoceke. Iimfuno zomphezulu: Umphezulu kufuneka ugudiswe kwaye ungabi nabumdaka ukuqinisekisa ukuchaneka komlinganiselo. Ukugcinwa kwezixhobo: Izixhobo kufuneka zilinganiswe kwaye zigcinwe rhoqo ukuqinisekisa ukuchaneka kunye nokuphindaphinda kovavanyo.
(2)HB5/750
① Indlela yokuvavanya kunye nomgaqo-siseko: Sebenzisa ibhola yentsimbi enobubanzi obuyi-5 mm ukucinezela kumphezulu wezinto eziphathekayo phantsi komthwalo we-750 kg, kwaye ulinganise i-identation diameter ukubala ixabiso lobunzima.
②Iintlobo zezinto ezisebenzayo: Isebenza kwizixhobo zetsimbi ezinobunzima obuphakathi, ezifana ne-alloys yobhedu, i-alloys ye-aluminium, kunye nentsimbi yobunzima obuphakathi. ③ Iimeko zesicelo eziqhelekileyo: Ukulawulwa komgangatho wezinto zetsimbi ezinobunzima obuphakathi. Uphando lwezinto eziphathekayo kunye nophuhliso kunye novavanyo lwebhubhoratri. Ukuvavanywa kobunzima bezinto eziphathekayo ngexesha lokuvelisa kunye nokulungiswa. ④ Iimpawu kunye neenzuzo: Umthwalo ophakathi: Isebenza kwizinto ezinobunzima obuphakathi kwaye inokulinganisa ngokuchanekileyo ubunzima babo. I-Flexible application: Isebenza kwizinto ezahlukeneyo ezinobunzima obuphakathi kunye nokuguquguquka okuqinileyo. Ukuphindaphinda okuphezulu: Ibonelela ngeziphumo ezizinzileyo nezingatshintshiyo zomlinganiselo.
⑥Amanqaku okanye imida: Ulungiselelo lwesampulu: Umphezulu wesampulu kufuneka ube mcaba kwaye ucoceke ukuqinisekisa ukuchaneka kweziphumo zomlinganiselo. Unyino lweMathiriyeli: Kwimathiriyeli ethambileyo kakhulu okanye eqine kakhulu, ezinye iindlela ezifanelekileyo zovavanyo lokuqina kunokufuneka zikhethwe. Ukugcinwa kwezixhobo: Izixhobo kufuneka zilinganiswe kwaye zigcinwe rhoqo ukuqinisekisa ukuchaneka nokuthembeka komlinganiselo.
(3)HB2.5/187.5
① Indlela yokuvavanya kunye nomgaqo-siseko: Sebenzisa ibhola yentsimbi kunye nobubanzi be-2.5 mm ukucinezela kwindawo yezinto eziphathekayo phantsi komthwalo we-187.5 kg, kwaye ulinganise i-diameter ye-indent ukubala ixabiso lobunzima.
②Iintlobo zemathiriyeli esebenzayo: Isebenza kwimathiriyeli yentsimbi ethambileyo kunye nezinye ialloys ezithambileyo, njenge-aluminiyam, ialloyi yokukhokela, kunye nentsimbi ethambileyo.
③Iimeko zosetyenziso eziqhelekileyo: Ulawulo lomgangatho wemathiriyeli yentsimbi ethambileyo. Uvavanyo lwezinto eziphathekayo kumashishini ombane kunye nombane. Uvavanyo lobunzima bezinto ezithambileyo ngexesha lokuvelisa kunye nokucubungula.
④Iimpawu kunye neengenelo: Umthwalo ophantsi: Usebenza kwizinto ezithambileyo ukunqanda ukujongwa ngokugqithisileyo. Ukuphindaphinda okuphezulu: Ibonelela ngeziphumo ezizinzileyo nezingatshintshiyo zomlinganiselo. Uluhlu olubanzi lwezicelo: Uyakwazi ukuvavanya iindidi zezixhobo zetsimbi ezithambileyo.
⑤ Amanqaku okanye izithintelo: Ukulungiswa kwesampuli: Umphezulu wesampuli kufuneka ube flat kwaye ucoceke ukuqinisekisa ukuchaneka kweziphumo zokulinganisa. Unyino lwezinto eziphathekayo: Kwimathiriyeli enzima kakhulu, kunokuba yimfuneko ukukhetha ezinye iindlela ezifanelekileyo zokuvavanya ubulukhuni. Ukugcinwa kwezixhobo: Izixhobo kufuneka zilinganiswe kwaye zigcinwe rhoqo ukuqinisekisa ukuchaneka komlinganiselo kunye nokuthembeka.
