ISO/TS 13471-1:2017 specifies procedures for determining the effect of temperature on tyre/road noise emission. Temperatures considered are tyre, road and ambient air temperatures. The noise emission for which this document is applicable is measured by means of ISO 11819‑2, or similar methods such as the on-board sound intensity (OBSI) method specified in Reference [1]. Measurement results obtained at a certain temperature, which may vary over a wide range, are normalized to a designated reference temperature (20 °C) using a correction procedure specified in this document.

ISO 17987-7:2016 specifies the conformance test for the electrical physical layer (EPL) of the LIN communications system. It is part of this document to define a test that considers ISO 9646 and ISO 17987‑4. The purpose of ISO 17987-7:2016 is to provide a standardized way to verify whether a LIN bus driver is compliant to ISO 17987?4. The primary motivation is to ensure a level of interoperability of LIN bus drivers from different sources in a system environment. ISO 17987-7:2016 provides all the necessary technical information to ensure that test results are consistent even on different test systems, provided that the particular test suite and the test system are compliant to the content of this document.

ISO/TS 18506:2014 provides a procedure to develop injury risk curves for biomechanical samples. These samples are often heavily censored and limited in size, such that specific steps and checks are required when developing injury risk curves. Moreover, several statistical methods were historically used to build injury risk curves. The curves resulting from the different methods could be rather close or fairly different, depending on the biomechanical samples. It is therefore of major importance to recommend a consensual method to be used. Otherwise, injury thresholds candidates to be included into regulations could be highly influenced by the statistical method used. These different methods were compared in a statistical simulation study. The conclusions of this study were used to recommend the survival analysis. ISO/TS 18506:2014 identifies steps to be followed to develop injury risk curves. It recommends preliminary checks, statistical method, and recommendation process of the injury risk curve. Guidelines on the type of the samples to be used (cadaver, animal, or dummy), as well as the variables to be used, and the injury severity level are beyond the scope of ISO/TS 18506:2014.

ISO 18418-1:2014 specifies the dimensional requirements of medium-pressure pipe end-connections for gasoline (spark-ignition) engine fuel injection equipment. It is applicable to externally threaded end-connections having a 60° female cone, as well as to the pipe end assemblies of medium-pressure fuel injection pipes with outside diameters of up to and including 10 mm.

Specifies the materials, design, construction and properties of a test surface in order to minimize intersite variation in vehicle noise measurements. Has been developed particularly for use with the ISO 362 and ISO 7188; can be used for vehicle noise testing generally where it is desirable to achieve a low level of tyre/road noise during the test. Does not take into account the influence on tyre/road noise of purely tyre-related parameters.
