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: g/kg.

5.2.2 Appropriate reporting units for predicting atmospheric emission impacts only if hours of fireplace use are factored in: g/h.

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. 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.
