Are we not allowed to copy/paste sections of standards (copyrighted materials)? I thought that was ok?

How is the portion from the floor up >to 80 cm above the floor properly illuminated in the test facility? The standard deals with this as well. But we shouldn't really be distributing this: 7.2 Arrangement of floor-standing equipment Floor-standing equipment should be mounted on a non-conductive support 0,05 m to 0,15 m above the supporting plane. The use of non-conductive supports prevents accidental earthing of the EUT and distortion of the field. To ensure the latter, the support shall be bulk non-conducting, rather than an insulating coating on a metallic structure. Floor-standing equipment which is capable of being stood on a non-conductive 0,8 m high platform, i.e. equipment which is not too large or heavy, or where its elevation would not create a safety hazard, may be so arranged. This variation in the standard method of test shall be recorded in the test report. NOTE Non-conductive rollers may be used as the 0,05 m to 0,15 m support. The equipment is then connected to power and signal wires according to relevant installation instructions. -- OOO - Own Opinions Only.
