The wo
15、rk of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governm
16、ental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The
17、main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

ISO shall not be held responsible for identifying any or all such patent rights. ISO 16110-2 was prepared by Technical Committee ISO/TC 197, Hydrogen technologies. ISO 16110 consists

38、t conditions/Test boundary Hydrogen generators may have different subsystems depending on types of primary conversion processes and applications, and they have different streams of material and energy in and out of them. However, a common system diagram and boundary has been defined for evaluation o

The following conditions shall be considered in order to determine the test boundary of the hydrogen generator: All energy recovery systems shall be included within the system boundary. Calculation of the heating value of the input fuel (such as natural gas,
40、propane gas, etc.) shall be based on the conditions of the input fuel at the boundary of the hydrogen generator. Calculation of the heating value of the output hydrogen containing gas stream shall be based on the conditions of the gas stream at the boundary of the hydrogen generator. Mechanical syst
41、ems required for hydrogen generator operation (i.e. ventilation or micro-turbines, expanders or compressors) shall be included inside the test boundary. The direct measurement of these mechanical systems inside the test boundary is not required; however, their effects shall be included in the hydrog
