O Iso 2006-All rights reserved lsO16750-1:2006(E) Foreword Iso(the International Organization for Standardization)is a worldwide federation of national standards bodies (Iso member bodies ). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with Iso, also take part in the work. Iso collaborates closely with the International Electrotechnical Commission(IEC)on all matters of electrotechnical standardization International Standards are drafted in accordance with the rules given in the ISo/EC Directives, Part 2 The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting Publication as an International Standard requires approval by at least 75 of the member bodies casting a vote Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. Iso shall not be held responsible for identifying any or all such patent rights so 16750-1 was prepared by Technical Committee ISo/TC 22, Road vehicles, Subcommittee SC 3 Electrical and electronic equipment This second edition cancels and replaces the first edition(ISo 16750-1: 2003), which has been technically revised Iso 16750 consists of the following parts, under the general title Road vehicles- Environmental conditions and testing for electrical and electronic equipment Part 1: general -Part 2: Electricalloads Part 3: Mechanical loads Part 4: Climatic oads Part 5: Chemical loads o Iso 2006-All rights reserved lso16750-1:2006(E Introduction The concept of Iso 16750 is to assist its user in systematically defining and/or applying a set of internationally accepted environmental conditions, tests and operating requirements, which are based on the anticipated actual environment in which the equipment will be operated in and exposed to during its life cycle The following environmental factors have been considered in the development of this iso 16750 World geography and climate Road vehicles are owned and operated in nearly all land regions of the earth. Significant variation in environmental conditions due to climatic environment, including diurnal and seasonal cycles, can therefore be expected. Consideration has been given to worldwide ranges in temperature, humidity, precipitation and atmospheric conditions including dust, pollution and altitude Type of vehicle Environmental conditions in and on road vehicles can depend on vehicle design attributes, such as engine type, engine size, suspension characteristics, vehicle mass, vehicle size, electrical supply voltage and so on Consideration has been given to typical types of vehicles including commercial (heavy) trucks, passenger cars and trucks and diesel and gasoline engines Vehicle use conditions and operating modes Environmental conditions in and on the vehicle vary significantly with road quality, type of road surface, road topography, vehicle use (e.g. commuting, towing, cargo transport, etc )and driving habit. Operating modes such as storage, starting, driving, stopping and so on, have been considered Equipment life cycle Electrical and electronic equipment are also resistant to environmental conditions experienced during manufacture, shipping handling, storage, vehicle assembly and vehicle maintenance and repair. Such conditions and test(e. g. handling drop test)are within the scope of Iso 16750 Vehicle supply voltage Supply voltage varies with vehicle use, operating mode, electrical distribution system design and even climatic conditions. Faults within the vehicle electrical system such as overvoltage alternator and intermittencies in connection systems, may occur. Such conditions are within the scope of Iso 16750 Mounting location in the vehicle In current or future car concepts, systems/components are mounted in almost any location of the car. the environmental requirements for each specific application highly depend on its mounting location. Each ocation in a car has its distinct set of environmental loads. As an example, the range of temperatures in the engine compartment differs significantly from the range in the passenger compartment. This is also true for the vibration loads. But in this case, not only the vibration levels are different, the type of vibration load also varies. Body mount components are typically exposed to random vibrations whereas for engine mount systems/components the additional sine vibration from the engine is considered. Devices installed in doors are exposed to a high number of mechanical shocks from door slamming additionall It is desirable for the car manufacturer to group the different environmental load types and levels in a reasonable number of standard requirement sets. This strategy makes it possible to carry systems/components from one car project to another. Furthermore, the exact requirement levels are often unknown when designing a component for a future car concept. The expected environmental loads are usually compiled from other car concepts with similar conditions. The grouping is normally done by mounting location, but it is difficult to define the right number of different mounting locations and respective load profiles, o Iso 2006-All rights reserved lsO16750-1:2006(E) because there is a conflict of aims between having only few requirement classes and tailoring to the requirement levels for each application The reason is that the environmental loads are not only depending on the mounting location. There are other major factors that effect the stress levels for systems/components. For examples, body styles, drive-train concepts or package densities can create absolutely different requirement levels for devices that are installed in different cars at almost the same location The concept of iso 16750 is to define requirement classes for separate load types. It distinguishes between electrical, mechanical, thermal, climatic and chemical loads. For each load type, several requirement classes are defined. Every requirement class is determined by a specific code letter. The complete environmental requirement set is created by defining the code letter combination. The code letters are defined in the respective clauses of this part of ISo 16750. Additionally, tables in the annexes of each part consists of usual mounting locations and define examples of their respective code letters For normal applications, these code letters are used. If an application is very specific and therefore the given code letter combinations can not be used, it is possible to create new code letter combinations to serve this purpose. In case none of the given code letters is useable, new requirement levels can be created by using the code letter Z. In this case, the specific requirements need to be defined separately, but it is desirable not to change the test methods is recommended to consider at least the following mounting locations for a device under test (DUT)with respect to thermal, mechanical climatic and chemical load a) Applicability to manufacturers responsibility Due to technology limitations or variations in vehicle design, the vehicle manufacturer may be required to place a component in a location where it cannot withstand the environmental conditions described in ISO 16750. Under these circumstances, it is the responsibility of the vehicle manufacturer to provide the necessary environmental protection b) Applicability to wiring harnesses, cables and electrical connectors Although some environmental conditions and tests in Iso 16750 may be relevant to vehicle wiring harnesses cables and connectors, its scope is not sufficient to be used as a complete standard. It is therefore not recommended that iso 16750 be directly applied to such devices and equipment. Applicable standards are taken into account c) Applicability to parts or assemblies in or on equipment iso 16750 describes environmental conditions and tests to be applied to electrical and electronic equipment directly mounted in or on the vehicle. It is not intended for direct application to parts or assemblies that are part of the equipment. For example, ISo 16750 should not be directly applied to integrated circuits(ICs)and discrete components, electrical connectors, printed circuit boards(PCBs), gauges, displays, controls, etc that are attached in or on the equipment. Electrical, mechanical, climatic and chemical loads for such parts and assemblies can be quite different from those described in ISo 16750 On the other hand, it is desirable to use iso 16750 to help derive environmental conditions and test requirements for parts and assemblies that are intended for use in road vehicle equipment. For example, a temperature range of -40c to 90C may be specified for an assembly contained inside a piece of equipment having a temperature range of -40C to 70C and a temperature rise of 20C d)Applicability relative to system integration and validation The user of iso 16750 is cautioned to understand that the scope of iso 16750 is limited to conditions and testing at the equipment level, and therefore does not represent all conditions and testing necessary for complete verification and validation of the vehicle system. Environmental and reliability testing of equipment parts and vehicle systems may be required For example, Iso 16750 does not necessarily ensure that environmental and reliability requirements for solder joints, solderless connections, integrated circuits, and so on are met. Such items are assured at the part, material or assembly level. Likewise, vehicle and system level testing is required to validate the equipment in the vehicle application o Iso 2006- All rights reserved INTERNATIONAL STANDARD so16750-1:2006(E Road vehicles- Environmental conditions and testing for electrical and electronic equipment Part 1 General 1 Scope This part of Iso 16750 applies to electric and electronic systems/components for vehicles.
