Scope
1.1 Inclusions
1.1.1
This Standard applies to appliances and self-contained packaged systems
a) manufactured after the date of publication of this Standard; and
b) that use gaseous or liquid fuels.
1.1.2
This Standard specifies requirements and test methods for the following devices within the field of cogeneration technologies that produce both electricity and thermal energy, including but not limited to,
a) combined heat and power (CHP) appliances, which generate electricity and thermal energy in a single integrated system:
i) internal combustion CHP;
ii) thermoelectric generators (TEG);
iii) vapour expansion cycle CHP;
iv) fuel cell CHP;
v) exhaust heat reclaimers; and
vi) stirling engine CHP; and
b) thermoelectric generators (TEG), which convert heat into electrical energy.
1.2 Ratings
This Standard applies to newly produced combined heat and power appliances with a maximum net electrical power output of 50kW.
These requirements apply to TEGs operating at inlet gas pressures not exceeding 250 psig (1720 kPa).
These requirements apply to TEGs operating at gas input rates of 100 000 Btu/h or less.
These requirements apply to fixed fuel piping systems. These requirements apply to indoor and outdoor installations.
For any other ratings, see the applicable appliance standards used in conjunction with this Standard.
1.3 Exclusions
This Standard does not apply to fuel storage systems.
1.4 Terminology
