This European Standard consolidates all the separate requirements specified in rolling stock TSLs and European Standards relating to bogies and running gear together into an overall requirement and process that ensures a functional and safe design is achieved for a defined operating envelope. There are many European Standards that specify the design requirements and associated processes of bogie and running gear components and sub-assemblies.There are also European Standards that specify vehicle performance and validation requirements that depend directly on the bogies or running gear.The objective of this standard is to bring all these separate design criteria together.This is accomplished by specifying the design and validation processes to be used for bogies and running gear with particular focus on the two key disciplines of dynamic behaviour and structural integrity.To ensure that safe operation can be continued througnout the product life the definition of a maintenance plan is also required.
This part of ISO 10846 specifies a method for determining the dynamic transfer stiffness for translations ofresilient supports, under specified preload. The method concerns the laboratory measurement of vibrations onthe input side and blocking output forces and is called "the direct method" The method is applicable to testelements with parallel flanges (see Figure 1).Resilient elements, which are the subject of this part of ISO 10848. are those which are used to reduce the transmission of vibration in the lower part of the audible frequency range (typically 20 Hz to 500 Hz) to a structure which may, for example, radiate unwanted fluid-borne sounri (airborne, waterborne or others), and the transmission of low-frequency vibrations (typically 1 Hz to 80 Hz), which may, for example, act upon human subjects or cause damage to structures of any size when vibration is too severe.NOTE I In practice, the size of tbe available test rig(s) can restrict the use of very small or very large resilient supportsNOTE 2 Samples of continuous supports of strips and mats are included in this method. Whether or not the sampledescribes the behaviour of the complex system sufficiently is the responsibility of the user of this part o1 I SO 10846Measurements for translations normal and transverse to the flanges are covered in this purl of ISO 10846.The direct method covers the frequency range from 1 Hz up to a frequency/UL, which is usually determinedby the test rigNOTE 3 Because of the large vadety of test rigs and test elements,/UL is variable In this part o1 ISO 10846, theadequacy of the test rig is not defined for a fixed frequency range, but on the basis of measured data, as described in 61to 6.4.
This part of ISO 10846 specifies a driving point method for determining the low-frequency transfer stiffness fortranslations of resilient supports, under a specified preload. The method concerns the laboratorymeasurement of vibrations and forces on the input side with the output side blocked, and is called the "drivingpoint method".The stiffness resulting from measuring the input displacement (velocity, acceleration) and input force is the dynamic driving point stiffness. Only at low frequencies, where the driving point stiffness and the transfer stiffness are equal, can this method be used for determination of the dynamic transfer stiffness.NOTE 1 In ISO 10846-2, the direct method for measuring the dynamic transfer stiffness is covered. The direct method covers the determination of the low-frequency dynamic transfer stiffness and it covers, in principle, a wider frequency range than the driving point method. Nevertheless, the driving point method is covered in the ISO 10846 series of international standards as well. It is considered as a valuable option for owners of (often expensive) test rigs for driving point stiffness measurements, to extend the use of these rigs with the determination of low-frequency dynamic transferstiffness.The method is applicable to test elements with parallel flanges (see Figure 1).Resilient elements, which are the subject of this part of ISO 10846, are those which are used to reducea) the transmission of vibration in the lower part of the audible frequency range (typically 20 Hz to 200 Hz) to a structure which may, for example, radiate unwanted fluid-borne sound (airborne, waterborne or others), andb) the transmission of low-frequency vibrations (typically 1 Hz to 80 Hz) which may, for example, act upon human subjects or cause damage to structures of any size when vibration is too severe.NOTE 2 In practice, the size of available test rig(s) determines restrictions for very small and for very large resilient supports.NOTE 3 Samples of continuous supports of strips and mats are included in the method. Whether or not the sampledescribes the behaviour of the complex system sufficiently is the responsibility of the user of this part of ISO 10846.Measurements for translations normal and transverse to the flanges are covered in this part of ISO 10846.The method covers the frequency range from f:l = 1 Hz to the upper limiting frequency fUL- Typically50 Hz ≤f<(index)UL> ≤ 200 Hz.The data obtained according to the method specified in this part of ISO 10846 can be used for the following:-- product information provided by manufacturers and suppliers;
ISO 26909:2009 specifies terms and definitions commonly used in the metal springs industry. Specifically, these terms appear in technical product documentation. Heat-treatment and surface-treatment terms pertinent to springs are included. Terms in ISO 26909:2009 are grouped into the following seven categories: a) general features of springs; b) application of springs in machinery and engineering; c) layouts and nomenclature of springs; d) specification requirements; e) design and calculation; f) manufacturing and processing; g) testing and inspection.
This British Standard specifies requirements for the safety of children’sbeds for domestic use with a maximum internal width of 1 000 mm anda maximum height of bed base of 600 mm .The requirements apply to children’s beds that are fully assembled andready for use.This British Standard does not apply to beds for adults, foldawaybeds, bunk and high beds, cabin/mid-height beds, children’s cots,bedside cots and children’s cots that allow free access for the child bymeans of a hinged opening or removal of some vertical bars/slats.This standard does not cover products that have been incorporated intochildren’s beds, for example luminaires, tables or storage furniture.
This European Standard applies to cylindrical helical compression springs made of round spring wire. Cold coiledcompression springs can be made with wire up to about 16 mm diameter. (See also EN 13906-1).Cylindrical helical springs made of round wire from European Standard materials are subject to the limiting values in Table 1.A specification for the parameters of cold formed helical compression springs is given in Annex B.
