Actually, here in Europe the European directives and their essential requirements are the law and harmonized standards are a recommended way to comply with them. The directives (with the essential requirements) are available for free. Unfortunately they are not as straight forward and easy to convert into product requirements as the standards. I wonder how much safer products would be if EN, IEC, ISO and UL standards where freely available. ETSI shows that standards can be free of charge. /Ruben On Tue, 15 Aug 2017 14:44:36 +0000, "Van Horn, David" wrote: > You must comply with the standards, but you have to pay to know what > they are... >=20 > Somehow, this is not right. >=20 >=20 > -----Original Message----- > From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On > Behalf Of alan.b.pearce@stfc.ac.uk > Sent: Tuesday, August 15, 2017 2:27 AM > To: piclist@mit.edu > Subject: RE: [EE] Precautions for long run 400 VDC cabling? >=20 >> (Access to standards is an irritation for me; used to be able to get >> at them through public library, but the library lost access.
