This document defines the classification methodology of time-constrained situations and their requirements, that are to be addressed by the "ExVe time critical interfaces" described in IS0 20077-1. Time-constrained situations include safety-critical situations.

The design of the vehicle needs a priority management of " ExVe time critical interface" resources in order to comply with time constrained situations requirements.

The methodology provides a classification, which will determine application priorities for optimal vehicle resource allocation.

This document series specifies performance requirements for targets used to assess the system detection and activation performance of active safety systems.

This part of ISO 19206 specifies the properties of bicyclist targets (BT) that represent a human bicyclist in terms of shape, movement, reflection properties, etc. for testing purposes.

The document addresses the detection requirements for a BT in terms of sensing technologies commonly in use at the time of publication of this document, and where possible, anticipated future sensing technologies. It also addresses methodologies to verify the target response properties to these sensors, as well as some performance requirements for the target carrier.

The BT according to this document is also representative for electrically assisted pedal bicycles (pedal electric cycle, pedelec).

This document does not address the test procedures in terms of speeds, positions, or timing of events. Performance criteria for the active safety system being tested are also not addressed.

This International Standard establishes and specifies uniform test procedures, conditions, equipment, and a performance report to permit the direct laboratory performance comparison of air cleaners.

The basic performance characteristics of greatest interest are air flow restriction or differential pressure, dust collection efficiency, dust capacity, and oil carry-over on oil bath air cleaners. This test code therefore deals with the measurement of these parameters.

This International Standard is applicable to air cleaners used on internal combustion engines and compressors generally used in automotive and industrial applications.

This document specifies technical requirements related to the ISO MOST data link layer functionality.

A MOST network is comprised of two or more nodes connected through a physical layer. The data link layer functionality is provided by each node. On each network, all nodes are synchronised and one node provides the system clock. This node is the TimingMaster, while all other nodes are TimingSlaves. The timing configuration of the node (TimingMaster or TimingSlave) determines the tasks that need to be performed on the data link layer.

The data link layer specifies the following subjects:

⎯ the service interface to the network layer;

⎯ the network frame, its areas and indicators;

⎯ the different network channels;

⎯ the different flow control mechanisms;

⎯ the load-adaptive arbitration and the round-robin arbitration;

⎯ the different addressing options;

⎯ the different cyclic redundancy checks, their usage and the CRC acknowledge;

⎯ the frame indicators.
