- description_Classification = {'A': '\n ## Class A (higher emission limits, industrial) \n \n **Class A** devices are devices that are suitable for use in all areas other than \n residential and such areas, and they are connected to the public mains.\n \n Devices must have emissions which are below the limits of Class A, \n but the emissions may exceed the limits of Class B.\n \n For Class A equipment, the instructions for use accompanying the product shall \n contain the following text: \n \n *Caution: This equipment is not intended for use in residential environments \n and may not provide adequate protection to radio reception in such environments.*', 'B': '\n ## Class B (lower emission limits, residential): \n \n **Class B** devices are devices that are suitable for use in residential areas \n and such areas, and they are connected to the public mains.'}
- description_Group = {'1': '\n ## Group 1: (general purpose applications)\n \n All equipment in the scope of EN 55011 (CISPR 11) which is not classified as Group 2 equipment. \n \n Examples of **Group 1** equipment:\n \n - Laboratory equipment\n - Medical electrical equipment\n - Scientific equipment\n - Semiconductor-converters\n - Industrial electric heating equipment with operating frequencies less than or equal to 9 kHz\n - Machine tools\n - Industrial process measurement and control equipment\n - Semiconductor manufacturing equipment\n - Switch mode power supplies', '2': '\n ## Group 2 (ISM RF applications): \n \n All ISM RF equipment in which radio-frequency energy in the frequency \n range 9kHz to 400GHz is intentionally generated and used or only used locally, in the form \n of electromagnetic radiation, inductive and/or capacitive coupling, for the treatment \n of material, for inspection/analysis purposes, or for transfer of electromagnetic energy. \n \n Examples of **Group 2** equipment:\n \n - Microwave-powered UV irradiating apparatus\n - Microwave lighting apparatus\n - Industrial induction heating equipment operating at frequencies above 9 kHz\n - Dielectric heating equipment Industrial microwave heating equipment\n - Arc Welding equipment\n - Microwave ovens\n - Medical electrical equipment\n - Electric welding equipment\n - Electro-discharge machining (EDM) equipment\n - Demonstration models for education and training\n - Battery chargers and power supplies – wireless power transfer (WPT) mode'}
- description_TestSetup = {'A': '\n ## Test Setup:\n \n On a test site, **Class A** equipment can be measured at a nominal distance d \n of 3m, 10m or 30m.\n \n **Class A** ***Group 1** equipment can be measured in situ, where the \n measurement takes place at a distance of 30m from the outer face of the exterior \n wall of the building in which the equipment is situated.\n \n **Class A** **Group 2** equipment can be measured in situ, where the measurement \n distance d from the exterior wall of the building in which the equipment is situated \n equals (30+x/a)m or 100m whichever is smaller, provided that the measuring \n distance d is within the boundary of the premises. In the case where the calculated \n distance d is beyond the boundary of the premises, the measuring distance \n d equals x or 30m, whichever is longer. For the calculation of the above values:\n\n - x is the nearest distance between the exterior wall of the building in which \n the equipment is situated and the boundary of the user’s premises in each \n measuring direction.\n - a = 2.5 for frequencies lower than 1 MHz.\n - a = 4.5 for frequencies equal to or higher than 1 MHz.', 'B': '\n ## Test Setup: \n \n On a test site, Class B equipment can be measured at a nominal distance d of 3m or 10m.\n \n - d < 10m. In the frequency range 30MHz to 1000MHz, a distance less than \n 10m is allowed only for equipment which complies with the definition \n for small size equipment. Small size equipment is either positioned on a \n table top or standing on the floor which, including its cables fits in an \n imaginary cylindrical test volume of 1.2m in diameter and 1.5m height \n (to ground plane).'}
