(a) The following definitions refer to commercial steam cookers:

1. (1) Commercial steam cooker, also known as compartment steamer, means a device for non-residential use with one or more food-steaming compartments in which the energy in the steam is transferred to the food by direct contact. Models may include countertop models, wall-mounted models, and floor models mounted on a stand, pedestal, or cabinet-style base.
2. (2) Cooking energy efficiency means the quantity of energy input to the food products; expressed as a percentage of the quantity of energy input to the appliance during the heavy-, medium-, and light-load tests.
3. (3) Heavy (potato) load cooking means the manufacturer’s stated capacity of 12 by 20 by 2½ inch (300 by 500 by 65 mm) perforated hotel pans each filled with 8.0 ± 0.2 lb (3.6 ± 0.1 kg) of fresh, whole, US No. 1, size B, red potatoes.
4. (4) Idle energy rate means the rate of appliance energy consumption while it is maintaining or holding at a stabilized operating condition or temperature.
5. (5) Product family means the individual models offered within a product line based on the same engineering design, including number of pans. Performance results across the models represented in the qualified product line shall be equivalent.
6. (6) Included products means products that meet the definition of a commercial steam cooker as specified herein are subject to the requirements of subdivision (b) of this section, with the exception of products listed in paragraph (7) of this subdivision.

7. (7) Excluded products means any product types not specifically defined in paragraph (6) of this subdivision are exempted from the New York standards.

   (b) Standard requirements for commercial steam cookers as is consistent with the efficiency levels established by ENERGY STAR V. 1.2 Specification for Commercial Steam Cookers, as incorporated by reference in section 509.61 of this Part.

8. (1) Cooking energy efficiency and idle energy rate requirements: Table 16: Requirements for Electric Steam Cooker Table 17: Requirements for Gas Steam Cooker

   Pan Capacity	Heavy Load Cooking Energy Efficiency	Idle Rate (watts)
   3-pan	50%	400
   4-pan	50%	530
   5-pan	50%	670
   6-pan and larger	50%	800

   Pan Capacity	Heavy Load Cooking Energy Efficiency	Idle Rate (Btu/h)
   3-pan	38%	6,250
   4-pan	38%	8,350
   5-pan	38%	10,400
   6-pan and larger	38%	12,500

9. (2) Significant digits and rounding:

   1. (i) All calculations shall be carried out with actual measured or observed values. Only the final result of a calculation shall be rounded. Calculated results shall be rounded to the nearest significant digit as expressed in the corresponding specification limit.

   2. (ii) Unless otherwise specified, compliance with specification limit shall be evaluated using exact values without any benefit from rounding.

      (c) Test procedures for assuring compliance with the standards established in subdivision (b) of this section.

10. (1) Representative models shall be selected for testing per the following requirements:

    1. (i) For qualification of an individual product model, the representative model shall be equivalent to that which is intended to be marketed and labeled as ENERGY STAR.
    2. (ii) For qualification of a product family, any model within that product family can be tested and serve as the representative model.

11. (2) When testing commercial steam cookers, the following test methods shall be used: Table 18: Test Method for Steam Cookers
