This document defines visual aspects for the identification and assessment of product characteristics for friction materials in terms of quality and for commercial and technical agreements. The sequence of the product characteristics represents no order of priority. Inspection is carried out in unused, “as supplied” condition.
In some characteristic features, there are differences between brake linings with an effective lining pad area less than 120 cm2 and larger than 120 cm2. The acceptance criteria ensure exclusion of any characteristics that could impact the function and performance of brake linings and applies unless
other agreements between the customer and the supplier.

This document specifies test methods to evaluate performance of the AEBS in car to pedestrian collision situations. Forward collision warning system (FCWS) is part of AEBS when it provides warning before braking intervention
Vehicle to pedestrian accidents occur when vehicle under test (VUT) drives straight line and either a pedestrian walks longitudinal on the same road or the pedestrian is approaching perpendicular the road.
A system requiring a driver intervention is not in scope of the document.
NOTE Depending on accidentology only a part of the scenarios can be used for an evaluation of performance.

This European Standard specifies requirements for the design, testing, performance and equipping of road ambulances used for the transport, monitoring, treatment and care of patients. It contains requirements for the patient’s compartment in terms of the working environment, ergonomic design and the safety of the crew and patients.This European Standard does not cover the training of the staff which is the responsibility of the authority/authorities in the country where the ambulance is to be registered.
This European Standard is applicable to road ambulances capable of transporting at least one person on a stretcher and excludes the transportation of hospital beds.
This standard also specifies requirements for ambulances intended to carry transport incubator systems.
The European Standard covers the specific requirements of each type of road ambulance which are designated according to the patient condition e.g. patient transport road ambulance types A1, A2, B and C.
This European Standard gives general requirements for medical devices carried in road ambulances and used therein and outside hospitals and clinics in situations where the ambient conditions can differ from normal indoor conditions.

This document specifies a standardized protocol for downloading data from the equipment control box to an in-vehicle board computer to ensure interchangeability between a vehicle and different equipment that the same vehicle can carry.
It specifies the interface connection as well as variables, records and reports which permit standardized protocol to cover applications with the greatest possible variety of equipment for performing winter maintenance and road service area maintenance.

This part of ISO 15765 specifies a transport protocol and network layer services tailored to meet the requirements of CAN‑based vehicle network systems on controller area networks as specified
in ISO 11898-1. It has been defined in accordance with the diagnostic services established in ISO 14229-1 and ISO 15031-5 but is not limited to use with them and is also compatible with most other communication needs for in‑vehicle networks.
ISO 11898-1 specifies variable length CAN frames with a maximum payload size dependent on the protocol device used. A CLASSICAL CAN protocol device can transmit/receive frames with payload sizes ranging from 0 bytes to 8 bytes per frame. A CAN FD (flexible data rate) protocol device can
transmit/receive frames with payload sizes from 0 bytes to 64 bytes. A CAN FD protocol device is also capable of transmitting/receiving CLASSICAL CAN frames.
The diagnostic communication over controller area network (DoCAN) protocol supports the standardized service primitive interface as specified in ISO 14229-2 (UDS).
This part of ISO 15765 provides the transport protocol and network layer services to support different application-layer implementations such as
— enhanced vehicle diagnostics (emissions-related system diagnostics beyond legislated functionality, non-emissions-related system diagnostics),
— emissions-related on-board diagnostics (OBD) as specified in ISO 15031,
— world-wide harmonized on-board diagnostics (WWH-OBD) as specified in ISO 27145, and
— end of life activation on on-board pyrotechnic devices (ISO 26021).
The transport protocol specifies an unconfirmed communication.
NOTE This part of ISO 15765 does not determine whether CLASSICAL CAN, CAN FD or both are recommended or required to be implemented by other standards referencing this part of ISO 15765.
