Emisije nepremičnih virov - Navodilo za uporabo standarda EN ISO 16911-1
To tehnično poročilo CEN zajema smernice za pomoč pri uporabi standarda EN 16911-1:2013. Izdelano je bilo kot odgovor na zahtevo zrcalnih odborov držav članic za pojasnitev elementov standarda EN 16911-1:2013 in načina interpretacije nekaterih zahtev, določenih v tem standardu. Standard EN 16911-1:2013 velja za nabor aplikacij v okviru različnih zahtev za negotovost. To tehnično poročilo CEN podaja priporočila o tem, katere zahteve in lastnosti delovanja veljajo za določene cilje spremljanja in področja uporabe, da bi bila dosežena enotna uporaba standarda EN 16911-1:2013. To tehnično poročilo CEN ne določa smernic glede uporabe standarda EN 16911-2:2013.
