The EN 50082-1 standard for EMC immunity requirements applies to electrical and electronic apparatus intended for use in the residential, commercial and light-industrial environment, as described in Clause 5, for which no dedicated product or product-family immunity standard exists.   Industrial environments according to EN 50082-1 are characterized by the existence of one or more of the following conditions: Industrial locations and medical apparatus, e.g. the presence of welding machines. Heavy inductive or capacitive loads are frequently switched. Current and associated magnetic fields are high. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No measurements need to be performed at frequencies where no requirements are specified. The EN 50082-1 standard applies to any apparatus intended to be directly connected to a public low-voltage mains network or connected to a dedicated DC source which is intended to interface between the apparatus and the low-voltage public mains network. It also applies to apparatus which is battery operated or is powered by a non-public but non-industrial low-voltage power distribution system if this apparatus is intended to be used in the locations described in Clause 5. This standard has been superseded by EN 61000-6-1.

The EN 50082-2 standard for EMC immunity requirements applies to electrical and electronic apparatus intended for use in the industrial environment, as described in Clause 5, for which no dedicated product or product-family immunity standard exists. Apparatus designed to radiate electromagnetic energy for radio communications purposes as defined by the ITU are excluded from this standard. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. Apparatus covered by this standard is not intended for connection to a public mains network but is intended to be connected to a power network supplied from a high or medium-voltage transformer dedicated for the supply of an installation feeding manufacturing or similar plant. This standard applies to apparatus intended to operate in industrial locations or proximity to industrial power installations. This standard also applies to battery operated apparatus intended to be used in the locations described in Clause 5. This standard was in use from September 15, 1995 to April 15, 2002, at which point it was then superseded by EN 61000-6-2.

EN 50191 is about providing protection against electric shock. The standard addresses specifically the erection and operation of electrical test installations in the workplace. It incorporates provisions from 11 other European Norm standards to provide details of good engineering practice when testing electrical equipment. Two harmonized standards are referred to in the text of EN 50191: HD 384 for voltages up to 1000 V and HD 637S1 for voltages exceeding 1000 V. Both documents are used when considering equipment for which the power supply does not fall within the scope of EN 50191. Table I lists other standards used as normative references. It is important to note that EN 50191 has no reference to CE marking or any other manufacturing product standard. The standard details five definitive test installations and the levels of protection required: Test Station with Automatic Protection against Direct Contact. The use of test enclosures encapsulates the device under test (DUT) and prevents any contact when the tests are applied. Test Station without Automatic Protection against Contact. This could be a product that is too large to allow the use of a test enclosure. Prohibited areas must be used with fixed barriers to prevent access to the DUT from unauthorized personnel. Test Laboratories and Experimental Stations. Each test area within a laboratory must be individually protected and isolated. A common emergency cutoff could increase risk to another area, increasing possible hazards at other test stations. Temporary Test Station. A skilled engineer conducts testing on a client's site or sets up a one-time test station to test a specially designed device. Individual assessment of the area and exclusion zones must be implemented to provide for the specific location and situation. Test Station without Test Personnel in Permanent Attendance. In situations in which automated production line or life testing is undertaken, full protection from

EN 55011 is a product family standard (largely based on CISPR 11) for industrial, scientific and medical (ISM) equipment and electro-discharge machining (EDM) and arc welding equipment. This standard sets forth procedures for the measurement of radio-frequency (RF) disturbances and limits within the frequency range of 9 kHz to 400 GHz. Requirements for ISM lighting apparatus and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are also contained in EN 55011. ISM equipment or appliances tested against EN 55011 under the EMC Directive are designed to generate and use locally, RF energy for industrial, scientific, medical, domestic or similar purposes, excluding applications in the field of telecommunication. Typical ISM applications are the production of physical, biological, or chemical effects such as heating, ionization of gases, mechanical vibrations, hair removal and acceleration of charged particles. Compliance with this standard gives a partial presumption of conformity with the European EMC Directive, 2004/108/EC. EN 55011 is an emission only standard covering radiated and conducted emissions. Most products will also require an assessment of immunity standards, such as: (1) EN 61326-1 – Electrical equipment for measurement, control, and laboratory use; or (2) EN 61000-6-2 – Generic Standards Immunity for industrial environments. These aforementioned two specifications contain additional requirements for electromagnetic interference and transient phenomenon. Additionally, devices powered via AC mains may require additional testing for power line harmonics and power line flicker. Although the term medical is in the title of this standard, EN 55011 does not apply directly to medical devices within the scope of the Medical Device Directive 93/42/EEC. The reason is that for medical devices falling within the scope of 93/42/EEC, the EMC directive does not apply directly, but

EN 55022 is a modified derivative of CISPR 22 that applies to information technology equipment (ITE) as defined as any equipment: – Which has a primary function of either (or a combination of) entry, storage, display, retrieval, transmission, processing, switching or control of data and of telecommunication messages and which may be equipped with one or more terminal ports typically operated for information transfer; – With a rated supply voltage not exceeding 600 V. Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified within the standard for protection of radio services in industrial, commercial or residential environments in the frequency range of 9 kHz to 400 GHz for both class A and class B equipment. The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results. Compliance with this standard gives partial presumption of conformity with the European EMC Directive, 2004/108/EC. Most products will also require assessment to the companion standard EN 55024, for immunity to electromagnetic interference and transient phenomenon. Additionally, devices powered via the AC mains, may require additional testing for power line harmonics and power line flicker. Information Technology Equipment (ITE), as would be tested for EN 55022, includes computer hardware and software, operating systems, web-based information and applications, telephones and other telecommunications products, video equipment and multimedia products, information kiosks, and office products such as photocopiers and fax machines. All European Standards, including EN 55022, are shaped by consensus among enterprises, public authorities, consumers, and trade unions, through a consultation process
