1.1本试验方法涵盖了测定木材燃烧室加热器和壁炉嵌件中木材火灾产生的颗粒物排放以及测定热输出和效率的燃料和操作方案。 1.2以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法用于测定木材加热器的排放率和排放系数。 排放系数有助于确定产品开发期间的排放性能。 排放系数对于空气质量监管机构确定是否符合排放性能限值非常有用。 排放率可能有助于空气质量监管机构确定木材加热器对空气质量的影响。 报告单位为每小时颗粒克数、每千克干燃料颗粒克数和每兆焦耳热输出颗粒克数。 比较所有类型固体燃料燃烧设备排放的适当报告单位:克/千克。 预测大气排放影响的适当报告单位:克/小时或克/兆焦耳。 本试验方法中规定的燃料负荷为统一尺寸的木床，与EPA方法28中规定的相同。EPA方法28中规定了婴儿床，以提供可重复的试验方法。在正常操作中，消费者使用的大多数燃料是形状和尺寸不规则的灯芯木。很少有数据表明本标准中规定的燃料床是否能够预测使用cordwood燃料的性能。 因此，本标准包括附录A1，该附录提供了使用软木的加油程序。它的提供是为了让那些有兴趣用软木测量排放性能的人有一个一致的方法来遵循。使用两种加油程序的比较数据库将提供数据，以确定使用婴儿床燃料的测试结果是否与使用软木燃料的测试结果相关。

1.1 This test method covers the fueling and operating protocol for determining particulate matter emissions from wood fires in wood-burning room heaters and fireplace inserts as well as determining heat output and efficiency. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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.
