(1) JJG99-90 kunye<Ubunzima> babe nemigaqo eneenkcukacha kwiulungelelwaniso iindlela ezahlukeneyoiiklasi zobunzima, ezisisiseko seukulinganisa abasebenzi.
(2) Kwiklasi yokuqalaiintsimbi, isatifikethi sokulinganisa kufunekabonisa ixabiso elilungisiweyo lobunzima kwivacuum, obona bunzima bukwivacuum kunye nexabiso elilungisiweyo lobunzima.
(3) Kwimilinganiselo yodidi lwesibini kunye nolusezantsi, isatifikethi sokulinganisa kufunekabonisa ixabiso lolungiso lobunzima kunye nelona xabiso lobunzima obuguquliweyo.
(4) Kwimigangatho yemigangatho, ngaphandle kokuba kukho iimfuno ezikhethekileyo, kuphela ukunyamezela okusemthethweniibonisiwe jikeleleulungelelwaniso isatifikethi, kwaye akukho maxabiso olungiso anikiweyo.
(5) Ubunzima obuveliswe phambi kwemigaqo ye-JJG99-90, iintsimbi eziqhelekileyo zinokuphathwa ngokwemigaqo elandelayo:
a. Kwimigangatho eqinileyo yeklasi yokuqala kunye neyesibini, isenokusetyenziswa njengemigangatho yokuqala kunye neyesibini.
b. Ngenxa yemimiselo emitsha, iklasi yokuqala, iklasi yesibini, i-E1, njl., 1 (E1), E2, njl., 2 (E2), F1, njl., 3 (F1) iintsimbi zeklasi kufuneka zibe yimizimba eqinile. ngayo yonke imathiriyeli. Ke ngoko, imilinganiselo yomgangatho wesibini ukuya kweyesine yodidi oluqhelekileyo olunolawulo lwesantyaimingxunya kufuneke kuiklasiF1 kwaye ngezantsi i iklasiF1.
c. Imimiselo emitsha ikwachaza ukuba ixabiso lolungiso lobunzima bebakala emva kowokuqalaulungelelwaniso okanye ukulungiswa akuyi kuba mkhulu kune-1 / yokunyamezela ubunzima. Ngokwale nqaku, ubunzima bokuqala bebakala lesibini ukuya kwelesihlanu kunye nohlengahlengisonge umgodi inokufakwa kwiklasi entsha kunye noluhlu lobunzima bebakala.
d. Umzekelo
1kg ubunzima beklasi yesibini kunye necavity yokulungelelanisa, ukunyamezela ubunzima±5mg, khangela i-F2 kunye nokunye ukunyamezela ubunzima±30mg; 4 (F2) iklasi yokunyamezela ubunzima itheyibhile yi±15mg. Ke ngoko, ubunzima busetyenziswa njengobunzima obuqhelekileyo obufana neF2, kunye neulungelelwaniso isiphumo siya kunika ixabiso lolungiso; ukuba ubunzima bokusebenza bubunzima bezinga le-4 (F2), akukho xabiso lokulungiswa liya kunikwa.
Kwi-1kg yeklasi ye-third-class weight with adjustment cavity, ingasetyenziswa njenge-M1 kunye ne-5 (M1) yeklasi yobunzima ngendlela efanayo.
Ngobunzima be-1kg yeklasi yesine kunye ne-cavity yokulungelelanisa, inokusetyenziswa njenge-M2 kunye ne-6 (M2) yeklasi yobunzima ngendlela efanayo.
Ukuqukumbela, ezi ziphumo zingentla zikwasebenza kubunzima bobunye ubunzima. Ubunzima beklasi yesi-2 ukuya kweyesi-5 (ngaphandle kodidi oluqinileyo lwe-2) luhlelwa njengeF2, M1, M2 okanyeiklasi4 (F2),iklasi5 (M1),iklasi6 (M2) kunyeiklasi7 (0) ubunzima beklasi.
