Pojem \u201coh\u0148ovzdorn\u00fd\u201d sa pou\u017e\u00edva najm\u00e4 v Eur\u00f3pe. Vo v\u0161eobecnosti sa vz\u0165ahuje na certifik\u00e1ciu syst\u00e9mu v oblasti nebezpe\u010dn\u00fdch l\u00e1tok len na medzin\u00e1rodn\u00e9 pou\u017eitie v s\u00falade so smernicami IEC. Bu\u010f je to tak, alebo je certifikovan\u00fd americk\u00fdm certifika\u010dn\u00fdm org\u00e1nom na pou\u017eitie v Spojen\u00fdch \u0161t\u00e1toch alebo Kanade. Tieto oh\u0148ovzdorn\u00e9 v\u00fdrobky s\u00fa \u010dasto vhodn\u00e9 na certifik\u00e1ciu z\u00f3nov\u00fdm syst\u00e9mom. Okrem toho sa m\u00f4\u017eete stretn\u00fa\u0165 s r\u00f4znymi normami pre oh\u0148ovzdornos\u0165.
IEC 60079-1 je norma, ktor\u00e1 sa zameriava na technick\u00e9 po\u017eiadavky na ozna\u010denie ex - db a pom\u00e1ha pri certifik\u00e1cii IEC na nehor\u013eavos\u0165. UL 60079-1 je \u010fal\u0161ia norma, ale zameriava sa na v\u00fdrobky, ktor\u00e9 si vy\u017eaduj\u00fa certifik\u00e1ciu pod\u013ea z\u00f3n a je ur\u010den\u00e1 len na pou\u017eitie v Spojen\u00fdch \u0161t\u00e1toch. CSA C22.2 \u010d. 60079-1 je podobn\u00e1 predch\u00e1dzaj\u00facej norme, ale je pou\u017eite\u013en\u00e1 len v Kanade.
Pod\u013ea tejto met\u00f3dy z\u00f3novania mo\u017eno klasifikova\u0165 skupiny plynov IIA, IIB a IIC. Plyny v skupine IIC s\u00fa najhor\u013eavej\u0161ie.<\/p>\n\n\n\n
Odolnos\u0165 proti v\u00fdbuchu<\/h2>\n\n\n\n
Ke\u010f hovor\u00edme o predmetoch odoln\u00fdch proti v\u00fdbuchu, zameriavame sa hlavne na predmety schv\u00e1len\u00e9 severoamerick\u00fdmi certifika\u010dn\u00fdmi org\u00e1nmi. Tie pou\u017e\u00edvaj\u00fa syst\u00e9m kateg\u00f3ri\u00ed\/oddelen\u00ed a zameriavaj\u00fa sa na polo\u017eky pou\u017e\u00edvan\u00e9 len v Spojen\u00fdch \u0161t\u00e1toch. Ke\u010f in\u0161talujete ak\u00fdko\u013evek certifikovan\u00fd syst\u00e9m na nebezpe\u010dnom mieste, m\u00f4\u017ee ma\u0165 svoju vlastn\u00fa kateg\u00f3riu a rozdelenie. Tie s triedou I a div\u00edziou I vedia, \u017ee sa pou\u017e\u00edva technol\u00f3gia ochrany proti v\u00fdbuchu. <\/p>\n\n\n\n
V\u0161imnite si, \u017ee severoamerick\u00e9 normy s\u00fa vytvoren\u00e9 spolo\u010dnos\u0165ami ANSI, FM, UL a CSA. Ak chcete z\u00edska\u0165 triedu I a div\u00edziu, znamen\u00e1 to, \u017ee mus\u00edte sp\u013a\u0148a\u0165 kanadsk\u00e9 normy CSA C22.2 \u010d. 30 alebo americk\u00e9 normy UL 1203. <\/p>\n\n\n\n
\u010eal\u0161\u00edm d\u00f4le\u017eit\u00fdm aspektom je, \u017ee v\u0161etky elektrick\u00e9 v\u00fdrobky v Spojen\u00fdch \u0161t\u00e1toch musia sp\u013a\u0148a\u0165 osobitn\u00e9 v\u0161eobecn\u00e9 bezpe\u010dnostn\u00e9 normy. Ak chcete z\u00edska\u0165 certifik\u00e1t pre nebezpe\u010dn\u00e9 miesta v tuzemsku, je to jeden z rozhoduj\u00facich faktorov. Stretnete sa s r\u00f4znymi skupinami plynov od A po D, pri\u010dom D je najmenej hor\u013eav\u00fd a A je najhor\u013eavej\u0161\u00ed.<\/p>\n\n\n\n

Jedn\u00fdm z hlavn\u00fdch rozdielov medzi nev\u00fdbu\u0161n\u00fdmi a oh\u0148ovzdorn\u00fdmi syst\u00e9mami je, \u017ee sa riadia odli\u0161n\u00fdmi protokolmi. Napr\u00edklad nev\u00fdbu\u0161n\u00e9 syst\u00e9my sa riadia protokolom NEC. Na syst\u00e9my odoln\u00e9 vo\u010di plame\u0148om sa v\u0161ak vz\u0165ahuje protokol IEC. Nehor\u013eav\u00e9 syst\u00e9my sa pou\u017e\u00edvaj\u00fa v Eur\u00f3pskej \u00fanii, zatia\u013e \u010do nev\u00fdbu\u0161n\u00e9 syst\u00e9my s\u00fa roz\u0161\u00edrenej\u0161ie v Spojen\u00fdch \u0161t\u00e1toch.<\/p>\n\n\n\n

\u010eal\u0161\u00ed rozdiel medzi nev\u00fdbu\u0161n\u00fdmi a oh\u0148ovzdorn\u00fdmi syst\u00e9mami spo\u010d\u00edva v sk\u00fa\u0161obn\u00fdch parametroch.

Na druhej strane, syst\u00e9my odoln\u00e9 vo\u010di plame\u0148om sa zvy\u010dajne testuj\u00fa na pretlak a in\u00e9 podmienky. Tlak, ktor\u00fd testuj\u00fa, je pribli\u017ene 1,5-n\u00e1sobok norm\u00e1lneho tlaku, pri\u010dom zriedkavo dosahuje \u0161tvorn\u00e1sobok tlakovej sk\u00fa\u0161ky.<\/p>\n\n\n\n
Ozna\u010denie<\/h2>\n\n\n\n
Ozna\u010denie nev\u00fdbu\u0161nosti je v s\u00falade s americk\u00fdmi normami a zameriava sa na triedu, div\u00edziu a skupinu. Ka\u017ed\u00e9 ozna\u010denie m\u00e1 svoju funkciu, preto\u017ee ozna\u010duje triedu t zariadenia, ale aj hor\u013eavos\u0165 plynu. Na konci ozna\u010denia z\u00edskate XP, \u010do znamen\u00e1, \u017ee pou\u017e\u00edvate nev\u00fdbu\u0161n\u00fa met\u00f3du.
Na druhej strane, oh\u0148ovzdorn\u00e9 ozna\u010denia sp\u013a\u0148aj\u00fa po\u017eiadavky certifik\u00e1cie syst\u00e9mu oblasti na z\u00e1klade umiestnenia. EX zobraz\u00ed nebezpe\u010dn\u00e9 miesto, zatia\u013e \u010do DB sa zameriava na po\u017eiarnu ochranu. Potom nasleduje ozna\u010denie IIC, ktor\u00e9 ozna\u010duje skupinu plynov. Nakoniec tu budete ma\u0165 teplotn\u00fa triedu od T1 do T6.<\/p>\n\n\n\n

Je dobre zn\u00e1me, \u017ee nehor\u013eavos\u0165 je jednou z mnoh\u00fdch technol\u00f3gi\u00ed odoln\u00fdch proti v\u00fdbuchu.

IEC je organiz\u00e1cia, ktor\u00e1 certifikuje ochrann\u00e9 zariadenia. Vo v\u0161eobecnosti plat\u00ed, \u017ee na z\u00edskanie certifik\u00e1cie nehor\u013eavosti alebo nev\u00fdbu\u0161nosti mus\u00edte ma\u0165 kryt, ktor\u00fd m\u00f4\u017ee pom\u00f4c\u0165 kontrolova\u0165 v\u0161etky reakcie na v\u00fdbuch.

Kon\u0161trukcia syst\u00e9mov odoln\u00fdch proti v\u00fdbuchu je \u0165a\u017e\u0161ia, zatia\u013e \u010do syst\u00e9my odoln\u00e9 proti plame\u0148om s\u00fa ove\u013ea \u013eah\u0161ie.
