(1) JJG99-90 ndi<Zolemera> kukhala ndi malamulo atsatanetsatane pakuwongolera njira zosiyanasiyanamakalasi za zolemera, zomwe ziri maziko acalibrating ogwira ntchito.
(2) Kwa oyambazolemera, satifiketi ya calibration iyenerasonyeza mtengo wokonzedwa wa misa mu vacuum, misa yeniyeni mu vacuum ndi mtengo wokonzedwa wa misa yotembenuzidwa.
(3) Pazolemera zamagulu achiwiri ndi otsika, satifiketi yoyeserera iyenerasonyeza mtengo wokonza misa ndi mtengo weniweni wa misa wotembenuzidwa.
(4) Pazolemera zamakalasi, pokhapokha ngati pali zofunikira zapadera, kulekerera kwalamulo kokha ndikoanasonyeza pa generalkuwongolera satifiketi, ndipo palibe zowongolera zomwe zimaperekedwa.
(5) Pazolemera zomwe zimapangidwa pamaso pa malamulo a JJG99-90, miyeso yokhazikika imatha kuyendetsedwa motsatira malamulo awa:
a. Kwa miyeso yolimba ya kalasi yoyamba ndi yachiwiri, imatha kugwiritsidwabe ntchito ngati miyeso ya kalasi yoyamba ndi yachiwiri.
b. Chifukwa cha malamulo atsopano, kalasi yoyamba, yachiwiri, E1, etc., 1 (E1), E2, etc., 2 (E2), F1, etc., 3 (F1) kalasi yolemera iyenera kukhala matupi olimba. za zinthu zonse. Chifukwa chake, zolemera zoyambira zachiwiri mpaka zinayi zokhala ndi liwiro lowongolerazibowo ayenera kukhalakalasiF1 ndi pansipa ndi kalasiF1.
c. Malamulo atsopanowa amafotokozanso kuti misala yokonza kulemera kwa kalasi itatha yoyambakuwongolera kapena kukonza sikudzakhala wamkulu kuposa 1/ ya kulolerana kulemera. Malinga ndi nkhaniyi, choyambirira chachiwiri mpaka chachisanu kalasi yolemera ndi kusinthandi pakamwa akhoza Kuphatikizidwa mu kalasi yatsopano ndi kalasi zolemetsa.
d. Chitsanzo
1kg kalasi yachiwiri kulemera ndi kusintha patsekeke, kulolerana misa±5mg, fufuzani F2 ndi kulolerana kwina±30 mg; 4 (F2) kalasi kulemera kulolera tebulo ndi±15 mg pa. Choncho, kulemera ntchito ngati muyezo kulemera monga F2, ndikuwongolera chotsatira chidzapereka mtengo wowongolera; ngati kulemera kwa ntchito ndi kulemera kwa msinkhu wa 4 (F2), palibe mtengo wowongolera umene udzaperekedwa.
Kwa 1kg ya kalasi yachitatu yolemera yokhala ndi zosinthika zosinthika, imatha kugwiritsidwa ntchito ngati miyeso ya kalasi ya M1 ndi 5 (M1) chimodzimodzi.
Kwa 1kg ya kalasi yachinayi yolemera yokhala ndi zosinthika zosinthika, ingagwiritsidwe ntchito ngati M2 ndi 6 (M2) zolemera zamakalasi mofanana.
Pomaliza, zotsatira zomwe zili pamwambazi zimagwiranso ntchito pazolemera za anthu ena. Zolemera zoyambirira za 2nd mpaka 5th class (kupatula kalasi yachiwiri yolimba) zimagawidwa ngati F2, M1, M2 kapenakalasi4 (F2),kalasi5 (M1),kalasi6 (M2) ndikalasi7 (0) zolemera zamakalasi.
