1.1
This Standard applies to newly produced gas-fired low-pressure steam and hot water boilers with gas inlet pressure ratings not exceeding 0.5 psi (3.5 kPa) and having input ratings of less than 12,500,000 Btu/hr (3 663 389 W) (see Clause 3, Definitions), hereinafter referred to as boilers*, constructed entirely of new unused parts and materials, for operation at or below the following pressures and temperatures:
Steam heating boilers 
   15 psi (103.42 kPa) steam pressure 
Hot water heating boilers 

This Part of this European Standard applies to all water-tube boilers as defined in EN 12952-1 which are heated by combustion of one or more fuels or by hot gases for the generation of steam and/or hot water.
This Part of this European Standard applies to those components between the feedwater inlet and the steam outlet of the steam generator. The quality of the steam produced is outside the scope of this standard.

Scope

1.1.1
This Model Code provides marking and test/construction requirements for the field evaluation of electrical equipment by an inspection body, where certification of that equipment is impracticable or otherwise unavailable.

1.1.2
Field-evaluated equipment found to be in conformity with the requirements of this Model Code is considered to be acceptable to the AHJ.

1.1.3

1 Scope
1.1 These requirements apply to non-networked embedded microprocessor software whose failure is capable of resulting in a risk of fire, electric shock, or injury to persons.
