27、and ANSI Z223/NFPA 70, as appli-cable. Griddles shall be delivered assembled, ready for con-nection to electricity or gas piping, or both, as applicable.7.2 Service ConnectionsProvisions for service shall beprovided in the back or bottom of the griddle. Types 1 and 2shall be capable of being banked
28、side by side.7.3 Electrical CharacteristicsAll electric griddles shall bedesigned for operation on nominal voltage ratings, Hz, andphases as specified by electrical class.7.4 Griddle SurfaceThe griddle surface shall not beporous, pitted, cracked, or distorted.7.5 ControlsThe temperature of each grid
29、dle section shallbe controlled by a temperature regulating device or thermostat.If switches and thermostats are located on the front panel, theyshall be recessed or otherwise protected from inadvertentchanges or damage. The temperature controlling device orthermostat shall be calibrated to maintain
30、the surface tempera-ture tolerance on each section not more than 25F (13.9C)except for those areas adjacent to the splash guards, the surfacetemperature tolerance shall not vary more than 30F (16.7C).7.6 Heating ElementsThe electric griddles shall haveheating elements arranged so that different area

32、l be enclosed by a heatinsulating pad or by a system of heat-reflecting baffles. Bothmethods shall be designed to isolate the heating elements byreducing the amount of heat radiated downwards. When aninsulating pad is used, it shall be fire resistant and suitable forthe temperatures generated in thi
33、s area. Heating elements shallF1919032be accessible readily for repair or replacement. The terminalsof the heating elements shall project a sufficient distance topermit easy access to the connections. All internal wiring shallbe free of stress or tension and, where required, shall be coatedwith high

38、 Performance TestingWhen specified in the contract orpurchase order, performance testing shall be performed inaccordance with Test Methods F 1275.9. Sampling and Quality Assurance9.1 SamplingWhen specified in the contract or purchaseorder, sampling for the inspection and tests contained in themain b
39、ody of this specification shall be performed in accor-dance with ANSI Z1.4.9.2 The griddles prepared for shipment shall be measuredand inspected by the manufacturer for compliance with thisspecification.10. Testing Methods10.1 Thermostat Test:10.1.1 Significance and UseThis test method determinescom
40、pliance with 7.5 and 8.1 surface temperature variancesfrom the thermostat setting requirements.10.1.2 The griddle shall be connected to the specified powersource. The thermostat shall be set at 300F (149C) and thegriddle allowed to operate until the temperature control hascycled “on” and “off” throu
41、gh at least three cycles at thissetting. The griddle surface then shall have five temperaturereadings taken per heating section. The readings shall be taken4 in. (102 mm) in from each corner and at the center of theheating section, that is, at the intersection of the diagonals fromcorner to corner o
42、f each heating section. The heating sectionsurface temperature shall be measured at each of the fivepoints. The high temperature at each point and the lowtemperature at each point shall be calculated. These tempera-tures shall conform to the tolerances specified in 7.5. Thisprocedure shall be repeat
43、ed at 325F (163C) and 350F(177C).11. Product Marking11.1 Each griddle shall be provided with an identificationplate in compliance with ANSI/Z83.11 or ANSI/UL 197.12.
