This document specifies data link independent requirements of diagnostic communication services. These allow a diagnostic tester (client) to control diagnostic functions in an in-vehicle electronic control unit (ECU, server) such as an electronic fuel injection, automatic gearbox, anti-lock braking system, etc. connected to a serial data link embedded in a road vehicle. This document specifies diagnostic communication services, which allow the diagnostic tester (client) to stop or to resume non-diagnostic message transmission, to read vehicle identification data and real-time sensor data, read and clear diagnostic information, control actuators, start/stop routines, and many more functions to assist in diagnosing the vehicle's electronic systems. This document does not apply to non-diagnostic message transmission on the vehicle's communication data link between two electronic control units. This document does not restrict an in-vehicle on-board tester (client) implementation in an ECU/server in order to utilize the diagnostic communication services on the vehicle's communication data link to perform bidirectional diagnostic data exchange.

ISO 16659 series provide different test methods aiming at assessing the performances of radioactive iodine traps in ventilation systems of nuclear facilities. This series deals with iodine traps with solid sorbent, mainly activated and impregnated charcoal, the most common solid sorbents used in ventilation systems of nuclear facilities, as well as other sorbents for special conditions (e.g. high temperature zeolites). ISO 16659-1 provides the general requirements to be applied for all methods of the series. The scope of this document is to provide general and generic requirements for the test method using cyclohexane (C6H12) as a tracer to determine the mechanical leakage rate of iodine trap. This reproducible method can support nuclear operators to compare the result with reference values given in safety reports. Unlike the method of radioactive methyl iodide described in ISO 16659-2, the cyclohexane field test method covered in this document does not directly give a decontamination factor for the iodine trap, but only the iodine trap performance information of an integrity test. Due to the use of the environmentally friendly test reagent of low-toxicity in the field tests, the method is mainly suitable for ventilation systems of those habitable spaces (e.g. main control rooms of nuclear power plants), and performance test of a single iodine trap before its delivery and acceptance. In addition, the method can also be used for iodine traps with activated carbon sampling canister (e.g. deep bed iodine trap Type III and Drawer iodine trap Type II).
