Inkcazo yeeMpawu zoBungqina bokuQhamuka

Ukumakishwa kobungqina bokudubula kwizixhobo zokukhanyisa ezikhusela uqhushumbo yileyibhile echaza ibakala lobungqina bokudubula., iqela lobushushu, uhlobo, kunye neendawo ezisebenzayo zokukhanyisa izibane.

Ingcaciso yokuMakisha okungaqhushumbayo:

Ngokwe-GB 3836 imigangatho, uphawu lokumakishwa kokuqhuma kwezibane zokukhanyisa lubandakanya:

Uhlobo olungaqhambukayo + ICandelo leZixhobo + (Iqela leGesi) + Iqela lobushushu.

1. Uhlobo olungaqhambukayo:

Itheyibhile 1 Iintlobo ezisisiseko zoBondo-bubungqina

Ifomu yobungqina bokudubula	Uphawu lwefomu yobungqina bokudubula	Ifomu yobungqina bokudubula	Uphawu lwefomu yobungqina bokudubula
Uhlobo lwe-flameproof	EX d	Uhlobo oluzaliswe isanti	EX q
Ukunyuswa kohlobo lokhuseleko	EX kunye	Encapsulation	EX m
Uhlobo lweBarotropic	EX p	N-uhlobo	EX n
Uhlobo olukhuselekileyo lwangaphakathi	EX ia EX i	Uhlobo olukhethekileyo	EX s
Uhlobo lokuhlasela kweoli	EX okanye	Uthuli-ubungqina uhlobo	EX A EX B

2. ICandelo leZixhobo:

Izixhobo zombane ze qhuma umoya wegesi wahlulwe waba:

Iklasi I: Ukusetyenziswa kwimigodi yamalahle;

Udidi II: Isetyenziselwa ukuqhuma kwimimoya yerhasi ngaphandle kwemigodi yamalahle.

Iklasi II-ubungqina bokudubula “d” kunye nokhuseleko lwangaphakathi “i” izixhobo zombane zahlulwa kwakhona zibe IIA, IIB, kunye neeklasi ze-IIC.

Izixhobo zombane ze uthuli oluvuthayo iindawo ezisingqongileyo zahlulwe zibe:

Uhlobo A lwezixhobo ezingaluthuli; Uhlobo B lwezixhobo ezingenaluthuli;

Uhlobo A lwezixhobo zokuthintela uthuli; Uhlobo B lwezixhobo zokuthintela uthuli.

3. Ingcaciso yokuMakisha okungaqhushumbayo:

Ukukwazi komxube werhasi eqhumayo ukusasaza ugqabhuko-dubulo kubonisa inqanaba lobungozi bogqabhuko-dubulo.. Okukhona amandla okusasaza ugqabhuko-dubulo, iphezulu ingozi. Obu buchule bunokumelwa ngowona msantsa uphezulu wovavanyo okhuselekileyo. Ukongeza, ukukhululeka kwegesi eziqhumayo, imiphunga, okanye inkungu ingaba yavutha ikwabonisa inqanaba lengozi yogqabhuko-dubulo, imelwe ngomlinganiselo ophantsi wokulayita ngoku. Udidi lwesibini lwezixhobo zombane ezingenakugqabhuka okanye zokhuseleko lwangaphakathi luhlelwa ngokwe-IIA, IIB, kunye ne-IIC ngokusekwe kumsantsa wabo osebenzayo wovavanyo okhuselekileyo okanye umlinganiselo okhoyo wokutshiza.
Itheyibhile 2 Ubudlelwane phakathi kweQela leMixube yerhasi eqhumayo kunye noMsantsa oPhezulu woMfuniselo oKhuselekileyo okanye uMyinge wokuIgniting waNgoku.

Iqela legesi	Ubukhulu besithuba sokhuseleko lovavanyo lwe-MESG (m m)	Ubuncinci bomlinganiselo wangoku wokutshisa i-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＞UMCR

4. Iqela lobushushu:

Umlilo ubushushu yomxube werhasi eqhumayo liqondo lobushushu elilinganiselweyo ekunokuvuthwa ngalo.
Izixhobo zombane zihlelwe ngokwamaqela e-T1 ukuya kwi-T6 ngokusekelwe kubushushu bawo obuphezulu bomphezulu, ukuqinisekisa ukuba ubushushu obuphezulu besixhobo alidluli ixabiso elivumelekileyo leqela lobushushu elihambelanayo. Ubudlelwane phakathi kwamaqela obushushu, isixhobo sobushushu bomphezulu, kunye nobushushu bomlilo we ezinokutsha iigesi okanye umphunga uboniswe kwiThebhile 3.

Itheyibhile 3 Ubudlelwane phakathi kwamaQela obushushu, Isixhobo soBubushushu boMphezulu, kunye noBubushushu bokuBuyisa kweeGasi ezinokutsha okanye imiphunga

Iqondo lobushushu IEC/EN/GB 3836	Obona bushushu bomphezulu buphezulu besixhobo se-T [℃]	Ubushushu be-Lgnition yezinto ezitshayo [℃]
T1	450	T＞450
T2	300	450≥T＞300
T3	200	300≥T＞200
T4	135	200≥T＞135
T5	100	135≥T＞100
T6	85	100≥T＞8

5. Iimfuno zokuSeta iiMakisho:

(1) Iimpawu kufuneka zibekwe ngokubonakalayo kumzimba oyintloko wesixhobo sombane;
(2) Iimpawu mazihlale zicacile kwaye zomelele phantsi komhlwa onokubakho kwikhemikhali. Iimpawu ezifana ne-Eks, uhlobo-ubungqina bokudubula, udidi, kunye neqela leqondo lokushisa linokuthi lifakwe embossed okanye i-debossed kwiindawo ezibonakalayo ze-casing. Izinto eziphathekayo zepleyiti yokumakisha kufuneka zixhathise iikhemikhali, ezifana nobhedu, ubhedu, okanye intsimbi engenasici.
