Shenhai e fakamoʻoni fakaʻauha
Ko e fakaʻilonga ʻo e fakamoʻoni fakaʻauha ʻi he maama ʻo e fakaʻauha hono naunau ko ha fakaʻilonga ia ʻoku ne fakamatalaʻi ʻa e maaka ʻo e fakamoʻoni fakaʻauha, kulupu mafana, taipeʻi, mo e ngaahi feituʻu ʻoku fekauʻaki mo e naunau ʻo e mama.
Fakamatala ki hono fakaʻilongaʻi ʻo e fakamoʻoni fakaʻauha:
Hange ko e GB 3836 ngaahi tuʻunga moʻuí, ʻOku kau ʻi hono fakaʻilongaʻi ʻo e mama hono naunau ʻa e:
Faʻahinga ʻo e fakamoʻoni fakaʻauha + Faʻahinga Meʻangāué + (Kulupu kasa) + Kulupu mafana.

2. Faʻahinga Meʻangāué:
Meʻangāue fakaʻuhila ki he fakafepakiʻi ʻOku vahevahe ʻa e atmospheres kasa ki he:
Kalasi ʻoku ou: Ke fakaʻaongaʻi ʻi he keliʻanga malala;
Kalasi II: Ke fakaʻaongaʻi ʻi he kasa atmospheres kehe mei he keliʻanga malala.
Kalasi II-fakamoʻoniʻi ʻo e fakaʻauha “d” mo e malu ʻoku ʻikai ke malu “i” ʻOku toe vahevahe lahi ange ʻa e meʻangaue fakaʻuhila ki he IIA, IIB, mo e ngaahi kalasi IIC.
Meʻangāue fakaʻuhila ki he combustible efu ʻOku vahevahe ʻa e ngaahi ʻatakai ki he:
Taipeʻi ha meʻangaue ʻoku malu ʻi he efu; Taipeʻi ʻa e meʻangaue ʻoku malu ʻi he efu;
Taipeʻi ha meʻangaue fakamoʻoniʻi ʻo e efu; Taipeʻi ʻa e meʻangaue ki hono fakamoʻoniʻi ʻo e efu.
3. Fakamatala ki hono fakaʻilongaʻi ʻo e fakamoʻoni fakaʻauha:
ʻOku fakahaaʻi ʻe he malava ko ia ʻe ha kasa ʻoku fio ke propagate ha fakaʻauha ʻa e tuʻunga fakatuʻutamaki ʻo e fakaʻauha. Ko e lahi ange ʻa e malava ko ia ke propagate ha fakaʻauha, ko e maʻolunga ange ʻa e fakatuʻutamaki. ʻE lava ke fakafofongaʻi ʻa e malava ko ʻeni ʻe he Experimental malu lahi taha. ʻIkai ngata ai, ʻa e faingofua ʻo e ngaahi kasa, ʻahu, pe ko e kakapu ʻe lava ke Maʻuʻanga Fakamatala toe fakahaaʻi foki ʻa e tuʻunga ʻo e fakaʻauha, fakafofongaʻi ʻe he igniting siʻisiʻi taha. ʻOku toe fakafaʻahinga ange ʻa e meʻangaue fakaʻuhila ki he IIA, IIB, pea IIC ʻo makatuʻunga ʻi heʻenau Experimental malu pe siʻisiʻi taha igniting fika lolotonga.
Tepile 2 Va fetuʻutaki ʻi he vahaʻa ʻo e kulupu ʻo e kasa Mixtures mo e Experimental malu lahi taha pe siʻisiʻi taha Igniting fika lolotonga
| Kulupu kasa | Sivi lahi taha ʻo e malu MESG (m) | Siʻisiʻi taha ignition e fika MICR |
|---|---|---|
| IIA | MESG≥0.9 | MICR>0.8 |
| IIB | 0.9>MESG≥0.5 | 0.8≥MICR≥0.45 |
| IIC | 0.5≥MESG | 0.45>MAʻU |
4. Kulupu mafana:
Ko e ignition mafana ʻo e ʻea ʻo ha kasa ʻoku fio ko e fakangatangata ʻo e ʻea ʻe lava ke maʻu ai.
ʻOku fakafaʻahinga ʻa e meʻangaue fakaʻuhila ki he ngaahi kulupu T1 ki he T6 ʻo makatuʻunga ʻi he mafana maʻolunga taha, fakapapauʻi ʻoku ʻikai laka hake ʻa e mafana ʻo e meʻangaue ʻi he mahuʻinga ʻo e kulupu mafana ʻoku fekauʻaki mo ia. Ko e va fetuʻutaki ʻi he vahaʻa ʻo e ngaahi kulupu mafana, mafana ʻo e meʻangaue, pea mo e mafana ignition ʻo e velangofua ʻOku ha ʻa e ngaahi kasa pe ʻahu ʻi he tepile 3.
Tepile 3 Va fetuʻutaki ʻi he vahaʻa ʻo e ngaahi kulupu mafana, Mafana ʻo e meʻangaue, mo Ignition mafana ʻo e ngaahi kasa velangofua pe ʻahu
| Levolo ʻo e ʻea IEC/EN/GB 3836 | Ko e mafana maʻolunga taha ʻo e meʻangaue T [° C] | Lgnition e mafana ʻo e ngaahi meʻa combustible [° C] |

5. Ngaahi fie maʻu ki hono fokotuʻu ʻo e ngaahi fakaʻilonga:
(1) ʻOku totonu ke fakaʻilongaʻi ʻa e ngaahi fakaʻilonga ʻi he tefitoʻi sino ʻo e meʻangaue fakaʻuhila;
(2) Kuo pau ke kei mahino mo tolonga ʻa e ngaahi fakaʻilonga ʻi he malumalu ʻo e kemikale corrosion. Ngaahi fakaʻilonga hange ko e ʻeke, faʻahinga ʻo e fakamoʻoni fakaʻauha, faʻahinga, pea ʻe lava ke lanu pe debossed ʻa e kulupu mafana ʻi he ngaahi konga ʻoku ʻasi mai ʻi he hiva. ʻOku totonu ke faitoʻi ʻa e naunau ki hono fakaʻilongaʻi ʻo e peleti, hange ko e polonise, palasa, pe stainless ukamea.
