SIGNIFICANCE AND USE
5.1 This test method is used for determining emission factors and emission rates for low mass wood-burning fireplaces.  
5.1.1 The emission factor is useful for determining emission performance during product development.  
5.1.2 The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.  
5.1.3 The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from fireplaces, but must be used with caution as use patterns must be factored into any prediction of atmospheric particulate matter impacts from fireplaces based on results from this method.  
5.2 The reporting units are grams of particulate per kilogram of dry fuel and grams of particulate per hour.  
5.2.1 Appropriate reporting units for comparing emissions from non-heating appliances: grams per kilogram.  
5.2.2 Appropriate reporting units for predicting atmospheric emission impacts only if hours of fireplace use are factored in: grams per hour.
SCOPE
1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from wood fires in low mass wood-burning fireplaces. The fueling and operating protocol for determining particular matter emissions from masonry or other high mass fireplaces is covered in Annex A1 of this test method.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its 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.

SIGNIFICANCE AND USE
5.1 The measurement of particulate matter emission rates is an important test method widely used in the practice of air pollution control.  
5.1.1 These measurements, when approved by federal or state agencies, are often required for the purpose of determining compliance with regulations and statutes.  
5.1.2 The measurements made before and after design modifications are necessary to demonstrate the effectiveness of design changes in reducing emissions and make this standard an important tool in manufacturer’s research and development programs.  
5.2 Measurement of heating efficiency provides a uniform basis for comparison of product performance that is useful to the consumer. It is also required to relate emissions produced to the useful heat production.  
5.3 This is a laboratory method and is not intended to be fully representative of all actual field use. It is recognized that users of hand-fired wood burning equipment have a great deal of influence over the performance of any wood-burning appliance. Some compromises in realism have been made in the interest of providing a reliable and repeatable test method.
SCOPE
1.1 This test method applies to wood-fired or automatically fed biomass burning hydronic heating appliances. These appliances transfer heat to the indoor environment through circulation of a liquid heat exchange media such as water or a water-antifreeze mixture.  
1.2 The test method simulates hand loading of seasoned cordwood or fueling with a specified biomass fuel and measures particulate emissions and delivered heating efficiency at specified heat output rates based on the appliance’s rated heating capacity.  
1.3 Particulate emissions are measured by the dilution tunnel method as specified in Test Method E2515. Delivered efficiency is determined by measurement of the usable heat output (determined through measurement of the flow rate and temperature change of water circulated through a heat exchanger external to the appliance) and the heat input (determined from the mass of dry fuel burned and its higher heating value). Delivered efficiency does not attempt to account for pipeline loss.  
1.4 Products covered by this test method include both pressurized and non-pressurized heating appliances intended to be fired with wood or automatically fed biomass fuels. These products are hydronic heating appliances which the manufacturer specifies for outdoor or indoor installation. They are often connected to a heat exchanger by insulated pipes and normally include a pump to circulate heated liquid. They are used to heat structures such as homes, barns, and greenhouses and can heat domestic hot water, spas, or swimming pools.  
1.4.1 Hydronic heating systems that incorporate a high mass heat storage system that is capable of storing the entire heat output of a standard fuel load are tested by the procedure specified in Annex A1. Systems that incorporate high mass heat storage capable of storing a portion of the output from a standard fuel load are tested by the procedure specified in Annex A2.  
1.5 Distinguishing features of products covered by this standard include:  
1.5.1 Manufacturers specify indoor or outdoor installation.  
1.5.2 A firebox with an access door for hand loading of fuel or a hopper and automated feed system for delivery of particulate fuel such as wood pellets or solid biomass fuel to a burn pot or combustion chamber.  
1.5.3 Typically a thermostatic control device that controls combustion air supply or fuel delivery, or both, to maintain the liquid in the appliance within a predetermined temperature range provided sufficient fuel is available in the firebox or hopper.  
1.5.4 A chimney or vent that exhausts combustion products from the appliance.  
1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not con...

SIGNIFICANCE AND USE
5.1 This test method is used for determining particulate matter (PM) emission rates and emission factors for wood heaters.  
5.2 This method is used in conjunction with Annex A2 for determining particulate matter (PM) emissions for Single Burn Rate heaters.  
5.3 Use of this test method in conjunction with Annex A1 and CSA B415.1 allows overall thermal efficiency, carbon monoxide emission rate, and particulate matter per unit of heat output to be determined.  
5.4 The fuel load specified in this test method is cordwood that is representative of the fuel actually burned in homes. The intent is that the results from this test method will be more predictive of in-home performance than other test methods using a lumber crib of uniform dimensions.
SCOPE
1.1 This test method covers the fueling and operating protocol for determining average particulate matter emissions from wood fires in wood-burning room heaters and fireplace inserts as well as options for determining heat output, efficiency, and carbon monoxide emissions.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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. Refer to 4.3.  
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.

SIGNIFICANCE AND USE
5.1 This test method is used for determining emission factors and emission rates for cordwood or other densified, binder free biomass fuel burning masonry heaters.  
5.1.1 The emission factor is useful for determining emission performance during product development.  
5.1.2 The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.  
5.1.3 The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from masonry heaters, but must be used with caution as use patterns must be factored into any prediction of atmospheric particulate matter impacts from masonry heaters based on results from this method.  
5.2 The reporting units are grams of particulate per kilogram of dry fuel (emissions factor), grams of particulate per hour of heating cycle (heating cycle emissions rate, based on the builder or manufacturer’s specified firing interval), and grams of particulate per hour of test run (combustion period emissions rate, based on the tested combustion period).  
5.3 Warning—Use of masonry heater emissions rate reporting numbers (grams per hour) for comparative purposes with other solid fuel burning appliances will require careful study of each of the appliance’s comparative operating characteristics in the given application. Intermittently fired appliances such as masonry heaters and continuously fired appliances such as wood and pellet stoves are not accurately compared by their respective emissions rates.
SCOPE
1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from solid fuel biomass (cordwood or other densified, binder free biomass fuels) fires in masonry heaters. It may also be used to test other similar appliances (see 3.2.20).  
1.2 This test method is applicable to the operation and fueling of masonry heaters during particulate emissions measurement test periods. The prescribed methods and procedures of these protocols are performed on masonry heaters installed and operated in accordance with the builder or manufacturer’s specifications.  
1.3 In conjunction with Test Method E2515, this test method provides a protocol for laboratory emissions testing of masonry heaters that is intended to simulate actual use in residential homes and other consumer applications. Since such actual use involves almost solely cordwood fueling, Annex A1, Cordwood Fuel, provides as close a simulation as is currently possible of consumer use, and is recommended for predicting actual consumer emissions performance. For regulatory and other potential uses in comparing relative emissions of various masonry heater products and designs, Annex A2, Cribwood Fueling, and Annex A3, Cribwood Fuel, Top-Down Burn, provide optional additional fueling protocols that substitute dimensional lumber cribs for the cordwood fuel. Data that establish the relationships between the emissions results generated by Annex A2 and Annex A3 and the emissions results generated by Annex A1 are not currently available.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.

SCOPE
1.1 This test method is applicable for the determination of particulate matter emissions from solid-fuel-burning appliances including woodstoves, pellet-burning appliances, factory-built fireplaces, masonry fireplaces, masonry heaters, indoor furnaces, and indoor and outdoor hydronic heaters within a laboratory environment.

In normal operation the majority of fuel used by consumers is cordwood with irregular shapes and dimensions. Very little data exists to indicate whether or not the fuel cribs specified in this standard yield results that are predictive of performance using cordwood fuel. This standard, therefore, includes Annex A1 which provides a fueling procedure using cordwood. It is provided so that those interested in measuring emissions performance with cordwood will have a consistent method to follow. A comparative database using the two fueling procedures will provide data to determine whether test results using crib fuel correlate to test results using cordwood fuel.

Some compromises in realism have been made in the interest of providing a reliable and repeatable test method.
SCOPE
1.1 This test method applies to wood-fired or automatically fed biomass burning hydronic heating appliances. These appliances transfer heat to the indoor environment through circulation of a liquid heat exchange media such as water or a water-antifreeze mixture.  
1.2 The test method simulates hand loading of seasoned cordwood or fueling with a specified biomass fuel and measures particulate emissions and delivered heating efficiency at specified heat output rates based on the appliance’s rated heating capacity.  
1.3 Particulate emissions are measured by the dilution tunnel method as specified in Test Method E2515. Delivered efficiency is determined by measurement of the usable heat output (determined through measurement of the flow rate and temperature change of water circulated through a heat exchanger external to the appliance) and the heat input (determined from the mass of dry fuel burned and its higher heating value). Delivered efficiency does not attempt to account for pipeline loss.  
1.4 Products covered by this test method include both pressurized and non-pressurized heating appliances intended to be fired with wood or automatically fed biomass fuels. These products are hydronic heating appliances which the manufacturer specifies for outdoor or indoor installation. They are often connected to a heat exchanger by insulated pipes and normally include a pump to circulate heated liquid. They are used to heat structures such as homes, barns, and greenhouses and can heat domestic hot water, spas, or swimming pools.  
1.4.1 Hydronic heating systems that incorporate a high mass heat storage system that is capable of storing the entire heat output of a standard fuel load are tested by the procedure specified in Annex A1. Systems that incorporate high mass heat storage capable of storing a portion of the output from a standard fuel load are tested by the procedure specified in Annex A2.  
1.5 Distinguishing features of products covered by this standard include:  
1.5.1 Manufacturers specify indoor or outdoor installation.  
1.5.2 A firebox with an access door for hand loading of fuel or a hopper and automated feed system for delivery of particulate fuel such as wood pellets or solid biomass fuel to a burn pot or combustion chamber.  
1.5.3 Typically a thermostatic control device that controls combustion air supply or fuel delivery, or both, to maintain the liquid in the appliance within a predetermined temperature range provided sufficient fuel is available in the firebox or hopper.  
1.5.4 A chimney or vent that exhausts combustion products from the appliance.

SCOPE
1.1 This test method is applicable for the determination of particulate matter emissions from solid-fuel-burning appliances including woodstoves, pellet-burning appliances, factory-built fireplaces, masonry fireplaces, masonry heaters, indoor furnaces, and indoor and outdoor hydronic heaters within a laboratory environment.
1.2 Analytes will be a particulate matter (PM) with no CAS number assigned. For data quality objectives, see Appendix X1.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.4 This test method 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 and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is used for determining emission factors and emission rates for cordwood or other densified, binder free biomass fuel burning masonry heaters.
The emission factor is useful for determining emission performance during product development.
The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.
The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from masonry heaters, but must be used with caution as use patterns must be factored into any prediction of atmospheric particulate matter impacts from masonry heaters based on results from this method.
The reporting units are grams of particulate per kilogram of dry fuel (emissions factor), grams of particulate per hour of heating cycle (heating cycle emissions rate, based on the builder or manufacturer’s specified firing interval), and grams of particulate per hour of test run (combustion period emissions rate, based on the tested combustion period).  
Warning—Use of masonry heater emissions rate reporting numbers (grams per hour) for comparative purposes with other solid fuel burning appliances will require careful study of each of the appliance’s comparative operating characteristics in the given application. Intermittently fired appliances such as masonry heaters and continuously fired appliances such as wood and pellet stoves are not accurately compared by their respective emissions rates.
SCOPE
1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from solid fuel biomass (cordwood or other densified, binder free biomass fuels) fires in masonry heaters. It may also be used to test other similar appliances (see 3.2.20).
1.2 This test method is applicable to the operation and fueling of masonry heaters during particulate emissions measurement test periods. The prescribed methods and procedures of these protocols are performed on masonry heaters installed and operated in accordance with the builder or manufacturer’s specifications.  
1.3 In conjunction with Test Method E2515, this test method provides a protocol for laboratory emissions testing of masonry heaters that is intended to simulate actual use in residential homes and other consumer applications. Since such actual use involves almost solely cordwood fueling, Annex A1, Cordwood Fuel, provides as close a simulation as is currently possible of consumer use, and is recommended for predicting actual consumer emissions performance. For regulatory and other potential uses in comparing relative emissions of various masonry heater products and designs, Annex A2, Cribwood Fueling, and Annex A3, Cribwood Fuel, Top-Down Burn, provide optional additional fueling protocols that substitute dimensional lumber cribs for the cordwood fuel. Data that establish the relationships between the emissions results generated by Annex A2 and Annex A3 and the emissions results generated by Annex A1 are not currently available.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is used for determining average emission rates and average emission factors for pellet heaters.
The emission factor is useful for determining emission performance during product development.
The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.
The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from pellet heaters.
The reporting units are grams of particulate per hour and grams of particulate per kilogram of dry fuel.
Appropriate reporting units for comparing emissions from all types of solid fuel fired appliances: g/kg.
Appropriate reporting units for predicting atmospheric emission impacts: g/h or g/MJ.
SCOPE
1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from fires in pellet or other granular or particulate biomass burning room heaters and fireplace inserts.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory limitations prior to use.

SIGNIFICANCE AND USE
This test method is used for determining emission rates and emission factors for wood heaters.
The emission factor is useful for determining emission performance during product development.
The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits.
The emission rate may be useful for the air quality regulatory community for determining impacts on air quality from wood heaters.
The reporting units are grams of particulate per hour, grams of particulate per kilogram of dry fuel and grams of particulate per megajoule of heat output.
Appropriate reporting units for comparing emissions from all types of solid fuel fired appliances: g/kg.
Appropriate reporting units for predicting atmospheric emission impacts: g/h or g/MJ.
The fuel load specified in this test method is a lumber crib of uniform dimensions, identical to that specified in EPA Method 28. Cribs were specified in EPA Method 28 to provide a reproducible and repeatable test method. In normal operation the majority of fuel used by consumers is cordwood with irregular shapes and dimensions. Very little data exists to indicate whether or not the fuel cribs specified in this standard yield results that are predictive of performance using cordwood fuel. This standard, therefore, includes Annex A1 which provides a fueling procedure using cordwood. It is provided so that those interested in measuring emissions performance with cordwood will have a consistent method to follow. A comparative database using the two fueling procedures will provide data to determine whether test results using crib fuel correlate to test results using cordwood fuel.

SIGNIFICANCE AND USE
The measurement of particulate matter emission rates is an important test method widely used in the practice of air pollution control.
These measurements, when approved by federal or state agencies, are often required for the purpose of determining compliance with regulations and statutes.
The measurements made before and after design modifications are necessary to demonstrate the effectiveness of design changes in reducing emissions and make this standard an important tool in manufacturer’s research and development programs.
Measurement of heating efficiency provides a uniform basis for comparison of product performance that is useful to the consumer. It is also required to relate emissions produced to the useful heat production.
This is a laboratory method and is not intended to be fully representative of all actual field use. It is recognized that users of hand-fired wood burning equipment have a great deal of influence over the performance of any wood-burning appliance. Some compromises in realism have been made in the interest of providing a reliable and repeatable test method.
SCOPE
