Cu toate acestea, atunci c\u00e2nd se preconizeaz\u0103 c\u0103 echipamentul va fi utilizat \u00eentr-un mediu aflat \u00een afara acestui interval de temperatur\u0103, aceasta este considerat\u0103 o situa\u021bie special\u0103. Marcajul trebuie s\u0103 includ\u0103 simbolul Ta sau Tamb \u00eempreun\u0103 cu limitele superioar\u0103 \u0219i inferioar\u0103 ale temperaturii mediului ambiant. Dac\u0103 acest lucru nu este posibil, simbolul \u201cX\u201d ar trebui s\u0103 indice condi\u021biile speciale de func\u021bionare, inclusiv limitele superioare \u0219i inferioare ale temperaturii ambiante. Aceasta \u00eenseamn\u0103 c\u0103, de obicei, cerin\u021ba privind temperatura ambiant\u0103 de -20 p\u00e2n\u0103 la 40 \u2103 pentru echipamente nu trebuie s\u0103 fie marcat\u0103 pe pl\u0103cu\u021ba de identificare sau pe certificatul de protec\u021bie \u00eempotriva exploziilor. Dar dac\u0103 echipamentul este destinat utiliz\u0103rii \u00eentr-un interval de temperatur\u0103 ambiant\u0103 diferit de acesta, trebuie s\u0103 fie marcat pe pl\u0103cu\u021ba de identificare a produsului \u0219i pe certificat \u0219i specificat \u00een manualul de utilizare.<\/p>\n\n\n\n

<\/figure><\/div>\n\n\n\nAtunci c\u00e2nd temperatura ambiant\u0103 este sub -20 \u2103, presiunea de referin\u021b\u0103 trebuie m\u0103surat\u0103 prin metode de temperatur\u0103 sc\u0103zut\u0103 sau presurizare prealabil\u0103. Presiunea de referin\u021b\u0103 ob\u021binut\u0103 \u00een acest mod este mult mai mare dec\u00e2t cea m\u0103surat\u0103 la temperatur\u0103 \u0219i presiune normale. <\/p>\n\n\n\n
Prin urmare, cerin\u021bele de rezisten\u021b\u0103 pentru carcasele echipamentelor electrice \u00een medii cu temperaturi sc\u0103zute sunt mai ridicate, iar acest lucru trebuie luat \u00een considerare \u00een timpul procesului de proiectare.<\/p>\n\n\n\n

Presiunea de explozie generat\u0103 \u00een acest fel este mai mare dec\u00e2t cea la temperatura \u0219i presiunea normale. <\/p>\n\n\n\n
