Nieuwe NEN 3140 sterk doorontwikkeld
Als trainer en adviseur NEN 3140, werk ik nu alweer een paar weken met de nieuwe NEN 3140 + A2 (December 2018). Deze nieuwe NEN 3140 is sterk doorontwikkeld. Veel zaken waar je in de praktijk vaak tegen aanloopt, zijn nu scherper en concreter geformuleerd. Ook zijn technische, organisatorische en maatschappelijke ontwikkelingen meegenomen in deze nieuwe uitgave.
Dat begint al bij de installatieverantwoordelijke
