1.1 These requirements apply to factory-built gas appliances having inputs of more than 400,000 Btu per hour, per individual combustion chamber which require flame failure and other precautions and which are intended primarily for commercial and industrial installation. The appliances...
1.1 These requirements cover oil-fired storage-tank water-heating appliances having a fuel input of not more than 200,000 Btu / hour (60 kW). These requirements do not apply to heaters that include storage vessels having a water capacity of more than 120 US gallons (454.2 L), or that are...
1.1 This standard covers the classification of coals by rank, that is, according to their degree of metamorphism, or progressive alteration, in the natural series from lignite to anthracite. 1.2 This classification is applicable to coals that are composed mainly of vitrinite. Note 1: Coals rich in...
1.1 This specification covers grades of pyrolysis liquid biofuel produced from biomass intended for use in various types of fuel-burning equipment under various climatic and operating conditions. These grades are described as follows: 1.1.1 Grade G is intended for use in industrial burners equipped...
4.1 The thermal resistance, R, of an insulation is used to describe its thermal performance. 4.2 The thermal resistance of an insulation is related to the density and thickness of the insulation. It is desirable to obtain test data on thermal resistances at thicknesses and densities related to the...
5.1 This test method was designed to give the manufacturer of loose-fill insulation products a way of determining what the initial installed thickness should be in a horizontal open attic for pneumatic applications. 5.2 The installed thickness value developed by this test method is intended to...
This standard applies to factory-made Unitary Air-conditioners and Unitary Air-source Heat Pumps with capacities less than 65,000 Btu/h as defined in Section 3. Energy Source. This standard applies only to electrically operated, vapor compression refrigeration systems. Purpose. The purpose...
5.1 Heat Gain to Space-This test method determines the heat gain to the space from a hood/appliance system. Note 2: To maintain a constant temperature in the conditioned space, this heat gain must be matched by space cooling. The space sensible cooling load, in tons, then equals the heat gain in...
4.1 This test method details the calibration and testing procedures and necessary additional temperature instrumentation required in applying Test Method C1363 to measure the thermal transmittance of fenestration systems mounted vertically in the thermal chamber. 4.2 The thermal transmittance of a...
1.1 These test methods 2, 3, 4 cover the atomic absorption determination of nickel in water and wastewaters. Three test methods are given as follows: Concentration Range Sections Test Method A-Atomic Absorption, Direct 0.1 to 10 mg/L 7 - 16 Test Method B-Atomic Absorption, Chelation-Extraction
4.1 The thermal resistance, R, of an insulation is used to describe its thermal performance. 4.2 The thermal resistance of an insulation is related to the density and thickness of the insulation. It is desirable to obtain test data on thermal resistances at thicknesses and densities related to the...
Description This LEC covers PPMS's that are designed to inactivate and disinfect waterborne pathogens and microorganisms within hot water distribution systems from replicating and infecting humans. These PPMS's include a water heater and distribution mixing valve, or water heater with integral...
This standard covers fluid heaters and related equipment. Within the scope of this standard, a fluid heater is considered to be any thermal fluid heater or process fluid heater with the following features: (1) Fluid is flowing under pressure. (2) Fluid is indirectly heated. (3) Release of energy...
This test method covers the estimation of the net heat of combustion (megajoules per kilogram or [Btu per pound]) of aviation gasolines and aircraft turbine and jet engine fuels in the range from 40.19 MJ ⁄kg to 44.73 MJ ⁄kg or [17 280 Btu ⁄lb to 19 230 Btu ⁄lb]. The precision...

1.1 This test method covers the measurement of the heat-transfer rate or the heat flux to the surface of a solid body (test sample) using the measured transient temperature rise of a thermocouple located at the null point of a calorimeter that is installed in the body and is configured to simulate...
Goal and scope definition During this phase of the LCA, a number of important decisions are made related to the goal and scope of the project. In defining the goal of the study, the following items are established related to the research: o the intended application and audience, o the reasons for...
3.1 Fig. 1 is a sectional view of an example circular foil heat-flux transducer. It consists of a circular Constantan foil attached by a metallic bonding process to a heat sink of oxygen-free high conductivity copper (OFHC), with copper leads attached at the center of the circular foil and at any...
