本文描述了评估通风燃烧装置回吸和泄漏的试验方法，并比较了这些试验的结果。试验包括诱导降压条件下的短期测量和自然条件下的连续监测。报告了来自两个地理区域42所房屋的数据。测试房屋的选择有意偏向于那些被认为更倾向于回溯的房屋。结果表明，尽管研究室的平均减压为1.9（1.3）Pa，但根据对排气压力和室内二氧化碳和一氧化碳浓度的连续监测，没有任何研究室出现任何明显的回吸或泄漏。 有限的正排气压力或回吸情况要么是由引风机引起的，要么是持续不到一分钟的过渡泄漏事件。短期测试的结果表明，10%至40%的研究房屋可能容易发生泄漏，但在现实生活条件下的持续监测并不支持这一结果。引文:研讨会论文，大西洋城，2002年

This paper describes test methods for assessment of back-drafting and spillage from vented combustion appliances and compares results from these tests. Tests included short-term measurements under conditions of induced depressurization and continuous monitoring under natural conditions. Data from 42 houses in two geographic areas are reported. The selection of houses for testing was intentionally biased toward ones thought to have a greater propensity for backdrafting. The results indicate that, while study houses were depressurized by an average of 1.9 (±1.3) Pa, none exhibited any significant backdrafting or spillage, based on continuous monitoring of vent pressures and indoor carbon dioxide and carbon monoxide concentrations. Limited cases of positive vent pressure or backdrafting either were caused by an induced draft fan or were transitional spillage events lasting less than a minute. Results of short-term tests, indicating that 10% to 40% of study houses might be spillage-prone, were not supported by continuous monitoring under real-life conditions.
