I’ve got a two part question, the first of which is in regards to CISPR11 Note 2 below:
4.2 Division into classes Class A equipment is equipment suitable for use in all establishments other than domestic and those directly connected to a low voltage power supply network which supplies buildings used for domestic purposes. Class A equipment shall meet class A limits. NOTE 1 Operation of equipment which does not meet the class A limits but does not result in unacceptable degradation of radio services may be sanctioned on a case-by-case basis by the competent national authority. NOTE 2 Although class A limits have been derived for industrial and commercial establishments, administrations may allow, with whatever additional measures are necessary, the installation and use of class A ISM equipment in a domestic establishment or in an establishment connected directly to domestic electricity power supplies. Class B equipment is equipment suitable for use in domestic establishments and in establishments directly connected to a low voltage power supply network which supplies buildings used for domestic purposes. Class B equipment shall meet class B limits. Who or what are the administrations referred to in the note? Part 2 – We have a client that produces test equipment used in the field for cable system setup and diagnostics. In normal use, this equipment would be used at the pole or pedestal but, on occasions it may be on customer premises in a residential neighborhood at the demarcation point. The equipment is a portable hand held device, battery powered and would only be in the area for several hours. Are there exceptions for a device like this regarding emissions classification? I didn’t find anything in the Directive, EN 61326-1 or CISPR11 except the excerpt above.
