Standard Overview Products Used in Testing Related Compliance Standards

Standard Overview
ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of tractors and other mobile agricultural machinery, forest machinery, landscaping, and gardening machinery as supplied by the machine manufacturer. It applies to machines and electrical/electronic sub-assemblies (ESA's) which are manufactured after the date of publication of this International Standard.

Electrical components or subassemblies intended for fitting in machines are also within the scope of this standard, except regarding immunity for those parts whose functions are not involved in the direct control and modification of the state of the functions of the machine.

For the purposes of ISO 14982, the following definitions apply (selected definitions follow)

Electromagnetic compatibility is defined as the ability of a machine or components or a separate technical unit to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment.
 
Electromagnetic disturbance: any electromagnetic phenomenon which may degrade the performance of a machine or component or separate technical unity.

Electromagnetic immunity: the ability of a machine or component or separate technical unit to perform in the presence of specified electromagnetic disturbances without degradation of performance.

Electromagnetic environment: the totality of electromagnetic phenomena existing at a given location.

The requirements of ISO 14982 shall be met by a machine operating in accordance with its final purpose. According to the choice of the machine manufacturer, the following alternatives are possible to demonstrate conformity with this International Standard.
 

  1. The requirements of this International Standard are deemed to be fulfilled for a complete machine when the requirements identified in clauses 5 and 6, as applicable, are fulfilled. If the machine manufacturer has chosen this alternative, no routine tests of the electrical systems or ESA's are required.

  2. The requirement of the International Standard is also deemed to be fulfilled if it is confirmed by the machine manufacturer that all electrical/electronic system of ESA's are in accordance with this International Standard and have been installed in conformance with the recommended requirements of the ESA.

  3. The requirements of this International Standard are also deemed to be fulfilled when the machine has no such equipment for which an immunity or interference test is required. In this case, no test is necessary.

No disturbances shall occur during testing which may affect the driver's direct control of the machine. The driver's direct control of the machine is exercised using steering, braking, the ground speed, or engine speed control. This also concerns the movements of parts of the machines and modifications of the state of function which may generate hazards or mislead others.

The electromagnetic emissions shall be measured using the method described in annex B at either of the defined antenna distances. The choice is left to the user according to the ISO 14982.

ISO 10605: Road Vehicles—Test Methods for Electrical Disturbances from Electrostatic Discharge
ISO 10605 covers testing procedures involving electrostatic discharge within road vehicles. ISO 10605  ISO 10605 is accredited by the Technical Committee ISO/TC 22 and Subcommittee SC 3. This test methods needed for electrical disturbances, which is caused by electrostatic discharge, are specified with ISO 10605 requirements. For example, charge build-ups made from movement inside a vehicle or during exiting can result in electrostatic discharge. ESD Tests  Tests that simulate an electrostatic discharge (ESD) into a vehicle electrical system are based on the human ESD model. Sensitive electrical devices can be adversely affected by energy either coupled or radiated from electrostatic discharges. This International Standard describes ESD tests that apply to both automotive electronic modules and vehicles.    ESD Waveforms for ISO 10605  There a four different discharge networks used to accomplish each waveform as required by ISO 10605. The different Resistance and Capacitance values affect the discharge output timing typically measured at 30 and 60ns. When changing networks, the decay time of the waveform changes and results are measured as listed in the table above.   Waveform 1 is the ESD discharge using a 330 pF/330 Ω network Waveform 2 is the ESD discharge using a 150 pF/330 Ω network Waveform 1 here is using a 330 pF/2000 Ω discharge network Waveform 2 here is using a 150 pF/2000Ω discharge network Starting Profile Waveform of ISO 10605-2 The starting profile waveform is created from from a Load Dump Simulator and a DC Source to simulate an automotive system during start up. This is traditionally seen in Internal Combustion Engine (ICE's) vehicles where cranking occurs upon startup. ISO 10605 Test Equipment  ATEC carries several products for ISO 10605 from industry-leading companies, including Haefely and Teseq. Please,
ISO 11452: Immunity Testing of Road Vehicle Components
ISO 11452 is a set of international standards and guidelines for the immunity testing of the electrical components found in commercial vehicles and passenger cars. ISO 11452 covers the testing of these components’ immunity to narrowband radiated electromagnetic energy without regard to the type of vehicle propulsion system. The sections of ISO 11452 are as follows: ISO 11452-1 | General principles & terminology ISO 11452-2 | Absorber-lined shielded enclosure ISO 11452-3 | Transverse electromagnetic (TEM) cell ISO 11452-4 | Harness excitation methods ISO 11452-5 | Stripline ISO 11452-7 | Direct radio frequency (RF) power injection ISO 11452-8 | Immunity to magnetic fields ISO 11452-9 | Portable transmitters ISO 11452-10 | Immunity to conducted disturbances in the extended audio frequency range ISO 11452-11 | Reverberation chamber ISO 11452-2 is a vehicle component immunity standard that applies to the 200 MHz to 18 GHz range. This standard, like many automotive, military and aerospace standards, calls for moderately high fields to be generated. At frequencies below 200 MHz, antennas get physically larger and also less efficient. For frequencies below 200 MHz, the standard recommends the methods stated in parts 4, 3, and 5 of the ISO 11452 Severity Level Field I 25 V/m II 50 V/m III 75 V/m IV 100 V/m V (open to the users of the standard). ISO 11452 recommends that these tests are performed in a shielded room. As is common with most immunity measurements, the intent of the test is to produce RF field levels which can be disruptive or damaging to the EUT; the shielded room removes the risk of unintended disruption to other sensitive devices or equipment outside of the test region. In the US, as in most other countries, there are limits on the radiation of energy without licenses, at frequencies that could affect licensed broadcasts.
ISO 11801:2002 - Information technology – Generic cabling for customer premises
Within customer premises, the importance of the cabling infrastructure is similar to that of other fundamental building utilities such as heating, lighting and mains power. As with other utilities, interruptions to service can have a serious impact. Poor quality of service due to lack of design foresight, use of inappropriate components, incorrect installation, poor administration or inadequate support can threaten an organization's effectiveness. Historically, the cabling within premises comprised both application specific and multipurpose networks. The original edition of this standard enabled a controlled migration to generic cabling and the reduction in the use of application-specific cabling. The subsequent growth of generic cabling designed in accordance with ISO/IEC 11801 has: a) contributed to the economy and growth of Information and Communications Technology (ICT), b) supported the development of high data rate applications based upon a defined cabling model, and c) initiated development of cabling with a performance surpassing the performance classes specified in ISO/IEC 11801:1995 and ISO/IEC 11801 Ed1.2:2000. NOTE ISO/IEC 11801, edition 1.2 consists of edition 1.0 (1995) and its amendments 1 (1999) and 2 (1999). This second edition of ISO/IEC 11801 has been developed to reflect these increased demands and opportunities. This International Standard provides: a) users with an application independent generic cabling system capable of supporting a wide range of applications; b) users with a flexible cabling scheme such that modifications are both easy and economical; c) building professionals (for example, architects) with guidance allowing the accommodation of cabling before specific requirements are known; that is, in the initial planning either for construction or refurbishment; d) industry and applications standardization bodies with a cabling system which supports current products and provides a basis for future product
