This international standard specifies a test method for steering effort measurement when manoeuvring a vehicle at low speed or with the vehicle stationary. It is mainly applicable to trucks having a mass exceeding 3,5 tonnes and buses and articulated buses having a mass exceeding 5 tonnes, according to ECE and EC vehicle classification. I.e. categories M3, N2, N3.
Note This standard may also be applicable to trucks having a mass not exceeding 3,5 tonnes and buses and articulated buses having a mass not exceeding 5 tonnes. I.e. categories M2, N1.

This ISO standard applies to heavy vehicles—that is, to commercial vehicles and buses as defined in ISO 3833 — that are covered by the categories M3, N2, N3, O3, and O4 of ECE and EC vehicle regulations. These categories pertain to trucks and trailers with maximum weights above 3,5 tonnes and to buses with maximum weights above 5 tonnes.
Vehicle suspension kinematic and compliance (K&C) properties that impact vehicle stability and dynamic behaviour are described in this standard and common methods of measurement are outlined. These methods are applicable to heavy vehicles. The measurements are performed on a single unit and typically one or two axles at a time.
This standard will define or reference the key suspension kinematic and compliance parameters necessary for characterizing and simulating vehicle suspension performance. These parameters also provide system-level descriptions of quasi-static behaviour that can be cascaded into subsystem and component performance targets. The suspension variables required for determining suspension characterization of one vehicle end, i.e. for a single axle or for multiple axles inter-related through suspension configuration (for example walking-beam), are provided. Metrics pertaining to the chassis connection between the front and rear suspensions are not included. Some typical methods of measurement will be discussed, however detail on how the measurements are executed is not within the scope of this standard.

This document specifies a method to predict and quantify misuse of child restraint systems (CRS) called Misuse Mode and Effect Analysis (MMEA). Such misuse can degrade the performance of CRSs.
As a predictive method it is intended to be applied at an early stage, before the CRS is put into use by consumers. The MMEA method is recommended to be used by manufacturers of CRSs.
Being predictive implies the possibility of incompleteness and errors. Such errors can be reduced if the proposed method is supported by field studies (for example according to ISO 13215-1) and panel method evaluation (for example according to ISO 13215-2).

This document specifies the requirements and methods for judging the risk of installation misuse of child restraint systems (CRS) with the help of assigned evaluation panels.
The methods described can be used regardless of type of installation of the CRS, e.g. with vehicle seat belts, ISOFIX/LATCH and different types of anti-rotation devices. The installation can include the evaluation of the interface between the child and the CRS, e.g. a harness or an impact shield.
This document is intended for technical assessment. It can be applied separately or in conjunction with the MMEA evaluation, described in ISO 13215-3.

This document specifies an engineering method for measuring the interior sound of road vehicles of categories M and N under typical driving conditions. It does not apply to agricultural tractors and field machinery.
It specifies the conditions for obtaining reproducible and comparable measurements of sound pressure levels inside a vehicle.
These measurements are used to obtain a representative average sound level during a typical driving cycle to enable assessment of adverse effects on human health.
The results may be used for
— standardized assessment of interior sound for comparisons (e.g. benchmark, consumer information programs);
— verification tests, to decide whether or not the sound inside the vehicle is in accordance to specifications;
— certification purposes, for example for evaluation of sound in relation to labour or for general health standards;
— monitoring tests, in order to check that the sound inside the vehicles is still within prescribed limits, and the noticeable changes have not occurred since delivery, or between individual units of a consignment of vehicles.
This document does evaluate the exposure to interior sound of vehicles in a way as it is commonly used for scientific effects on human health.
It does not assess maximum interior sound of a vehicle under extreme driving situations, as the today’s measured maximum sound pressure levels inside vehicles are far away from the risk to create instantaneous hearing damages.

This document specifies conformance tests in the form of an abstract test suite (ATS) for a system under test (SUT) implementing an EVCC or SECC according to ISO 15118-2. These conformance tests specify the testing
of capabilities and behaviors of an SUT as well as checking what is observed against the conformance requirements specified in ISO 15118-2 and against what the supplier states the SUT implementation's capabilities are.
The capability tests within the ATS check that the observable capabilities of the SUT are in accordance with the static conformance requirements defined in ISO 15118-2. The behavior tests of the ATS examine an
implementation as thoroughly as is practical over the full range of dynamic conformance requirements defined in ISO 15118-2 and within the capabilities of the SUT (see NOTE).
A test architecture is described in correspondence to the ATS. The conformance test cases in this part of the standard are described leveraging this test architecture and are specified in TTCN-3 Core Language for ISO/OSI Network Layer (Layer 3) and above. The conformance test cases for the Data Link Layer (Layer 2) and Physical Layer (Layer 1) are described in Part 5 of this standard. Test cases with overlapping scopes are explicitly
detailed.
This document does not include specific tests of other standards referenced within ISO 15118-2, e.g. IETF RFCs. Furthermore, the conformance tests specified in this International Standard do not include the assessment of performance nor robustness or reliability of an implementation. They cannot provide judgments on the physical realization of abstract service primitives, how a system is implemented, how it provides any requested service, nor the environment of the protocol implementation. Furthermore, the test cases defined in this standard only consider the communication protocol defined ISO 15118-2. Power flow between the EVSE and the EV is not considered.
NOTE 1 Practical limitations make it impossible to define an exhaustive test suite, and economic considerations may restrict testing even further. Hence, the purpose of this part is to increase the probability that different implementations can interwork. This is achieved by verifying them by means of a protocol test suite, thereby increasing the confidence that each
implementation conforms to the protocol specification. However, the specified protocol test suite cannot guarantee conformance to the specification since it detects errors rather than their absence. Thus, conformance to a test suite alone cannot guarantee interworking. What it does do is give confidence that an implementation has the required capabilities and that its behavior conforms consistently in representative instances of communication.
NOTE 2 This standard has some interdependencies to the conformance tests defined in ISO 15118-5 which result from ISO/OSI cross layer dependencies in the underlying protocol specification (e.g. for sleep mode)
