Okoljski inženiring (EE) - Okoljski pogoji in preskusi vplivov okolja za telekomunikacijsko opremo - 1-1. del: Klasifikacija okoljskih pogojev - Skladiščenje
Ta dokument opredeljuje razrede okoljskih pogojev in njihovih mejnih vrednosti, ki jim je telekomunikacijska oprema lahko izpostavljena med shranjevanjem. Navedene mejne vrednosti so tiste, za katere je verjetnost, da bodo prekoračene, majhna; v splošnem manj kot 1 %.
OPOMBA 1: Začasno shranjevanje med prevozom je vključeno v delu 1-2: Prevoz.
OPOMBA 2: Če je oprema shranjena v svoji embalaži, veljajo okoljski pogoji za opremo v embalaži.
