Standard Specification for Heat Meter Instrumentation

ABSTRACT
This specification applies to heat meters used to measure heat in heat exchange circuits in which energy is absorbed (cooling) or given up (heating) by a flowing liquid. For this specification, the necessary elements of a heat meter consist of a sensor to measure flow of the heat-conveying liquid, a pair of temperature sensors that measure the temperature differential across the heat exchange circuit, and a device that receives input from the flow and temperature sensors and calculates energy. This specification does not cover electrical safety or mechanical safety (including pressure safety).
This specification defines heat meters as complete or combined instruments. A complete instrument refers to a heat meter that does not have separable subassemblies, while a combined meter is a heat meter that has separable subassemblies. It specifies the allowable flow rate maximum permissible error (MPE) by accuracy class and turndown; the combined allowable error percentages for the temperature sensor pair and the heat calculator for measured difference temperatures in –17°C [2°F] increments; maximum lead cross section and length requirements; types of instruments; metrological characteristics of flow sensors of heat meters and complete instruments; data exchange and communications protocols; heat meter testing methods; operating conditions during testing; type approval tests and measurements; surge transients for signal and dc lines; surge transients for ac power lines; carrier frequencies; field strength; initial verification tests; test temperature ranges; product marking and inscriptions; and installation and operation instructions.
SCOPE

ASTM E1356-23(Test Method)
Standard Test Method for Assignment of the Glass Transition Temperatures by Differential Scanning Calorimetry

SIGNIFICANCE AND USE
5.1 Differential scanning calorimetry provides a rapid test method for determining changes in specific heat capacity in a homogeneous material. The glass transition is manifested as a step change in specific heat capacity. For amorphous and semicrystalline materials the determination of the glass transition temperature may lead to important information about their thermal history, processing conditions, stability, progress of chemical reactions, and mechanical and electrical behavior.  
5.2 This test method is useful for research, quality control, and specification acceptance.
SCOPE
1.1 This test method covers the assignment of the glass transition temperatures of materials using differential scanning calorimetry or differential thermal analysis.  
1.2 This test method is applicable to amorphous materials or to partially crystalline materials containing amorphous regions, that are stable and do not undergo decomposition or sublimation in the glass transition region.  
1.3 The normal operating temperature range is from −120 °C to 500 °C. The temperature range may be extended, depending upon the instrumentation used.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 ISO standards 11357–2 is equivalent to this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Estimating Kinetic Parameters by Differential Scanning Calorimeter Using the Borchardt and Daniels Method

SIGNIFICANCE AND USE
6.1 This test method is useful in research and development.  
6.2 The determination of the appropriate model for a chemical reaction or transformation and the values associated with its kinetic parameters may be used in the estimation of reaction performance at temperatures or time conditions not easily tested. This use, however, is not described in this test method.
SCOPE
1.1 This test method describes the determination of the kinetic parameters of activation energy, Arrhenius pre-exponential factor, and reaction order using the Borchardt and Daniels2 treatment of data obtained by differential scanning calorimetry. This test method is applicable to the temperature range from 170 K to 870 K (−100 °C to 600°C).  
1.2 This treatment is applicable only to smooth exothermic reactions with no shoulders, discontinuous changes, or shifts in baseline. It is applicable only to reactions with reaction order n ≤ 2. It is not applicable to acceleratory reactions and, therefore, is not applicable to the determination of kinetic parameters for most thermoset curing reactions or to crystallization reactions.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM E3367-23(Test Method)
Standard Test Method for Determining the Combustion Behavior of Layered Assemblies using a Cone Calorimeter

SIGNIFICANCE AND USE
5.1 Flammable liquid products can be generated by either pyrolysis or melting of polymers. Materials that generate flammable liquid products include thermoplastic polymers (for example, polyolefins) and thermosetting polymers (for example, polyurea and flexible polyurethane), which degrade to yield, in part, liquid pyrolyzates when pyrolyzing. Such liquid material can accumulate underneath a burning item and eventually ignite to form a pool fire, generally leading to a sharp increase in heat release rate and increase in fire hazard.  
5.2 Fire barriers are able to hinder the formation of a pool fire by delaying the generation and the release of flammable liquid products.  
5.3 This test method is intended to simulate the combustion of a central (that is, away from the edges) cross-section of a single material or a multi-layered product with ignition occurring on the top surface of the specimen.  
5.4 The test method is designed to assess whether liquid products are released during the test and the time at which they are released.  
5.5 The test method is designed to assess whether dripping occurs during the test and the time at which it occurs.  
5.6 The test method is designed to assess whether bottom ignition occurs during the test and the time at which it occurs.  
5.7 The test method is designed to assess whether pool ignition occurs during the test and the time at which it occurs.  
5.8 The test method is designed to assess whether burn-through occurs during the test and the time at which it occurs.  
5.9 The test measures heat release rate, mass loss rate and the resulting smoke obscuration as a result of exposing the specimen to a radiant heat source.  
5.10 The test method assesses whether the components of the specimen under examination demonstrates any of the following behaviors: breaking open, charring, appearance of superficial cracks without complete separation of the parts, melting, or shrinkage.  
5.11 The test method does not assess flame s...
SCOPE
1.1 This test method covers a means to measure the response of materials, products or layered assemblies when exposed to controlled levels of radiant heating, with or without an external ignitor.  
1.2 This test method provides an alternative test configuration to Test Method E1354 to measure the ignitability, heat release rate (including peak heat release rate and total heat released), mass loss rate, effective heat of combustion and visible smoke development.  
1.3 Compared to Test Method E1354, this test method adds the ability to measure the time at which the following phenomena occur: (1) appearance of liquid products (generated by either melting or pyrolysis of the specimen) underneath the sample, dripping and generation of a liquid pool underneath the specimen, (2) flaming over the bottom surface of the specimen and liquid pool, and; (3) burn-through.  
1.4 This test method is not intended to measure the response of products comprised of noncombustible cores.  
1.5 The top side of the specimens shall be exposed to an initial test heat flux of 0 kW/m2 to 75 kW/m2. External ignition, if any, shall be by electric spark.  
1.6 This test method has been developed for use to evaluate the fire test response characteristics of materials, products or layered assemblies. It is potentially useful for mathematical modeling, material or product design purposes, and research and development.  
1.7 This test method is used to measure and describe the response of assemblies to heat and flame under controlled conditions but does not by itself incorporate all factors required for fire hazard or fire risk assessment of an end-use product under actual fire conditions.  
1.8 This test method is used to measure the effect of fire barriers on the burning behavior of materials, products or layered assemblies to a range of radiant heat intensities but does not account for all factors that affect the performance of fire barriers at ...

Standard Test Method for Thermal Conductivity and Thermal Diffusivity by Modulated Temperature Differential Scanning Calorimetry

SIGNIFICANCE AND USE
5.1 Thermal conductivity is a useful design parameter for the rate of heat transfer through a material.  
5.2 The results of this test method may be used for design purposes, service evaluation, manufacturing control, research and development, and hazard evaluation. (See Practice E1231.)
SCOPE
1.1 This test method describes the determination of thermal conductivity of homogeneous, non-porous solid materials in the range of 0.10 W/(K·m) to 1.0 W/(K·m) by modulated temperature differential scanning calorimeter. This range includes many polymeric, glass, and ceramic materials. Thermal diffusivity, which is related to thermal conductivity through specific heat capacity and density, may also be derived. Thermal conductivity and diffusivity can be determined at one or more temperatures over the range of 0 °C to 90 °C.  
1.2 The values stated in SI units are to be regarded as standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
