standard for E-E/ NF C 17102 standard has een %ulished in 1334' and
worldwide it has een decided to revise the three standards fro" France
-%ain and Portugal in a %arallel %rocedure ased on a Franco-%anish
wor!ing grou% that has een followed carefull Portugal. ,his NFC C 17102/2011 standard is now a%%roved in France and at the ti"e of writing the
%a%er the -%anish standard 5NE 2116/2011 has 8ust %assed the national
%ulic en9uir and is going to e %ulished a%%ro:i"atel in two wee!s and
Portugal standard NP;;22 is on the a%%roval %rocedure.
