密閉式撒水頭認可基準適用性之研究

密閉式撒水頭認可基準自民國90年公告執行以來，基準內容有許多窒礙難行或與現行設置標準無法契合之處，其規範適用性影響產品之銷售、後端設置及安裝甚巨。本研究比較國內外密閉式撒水頭相關設置及檢驗規範，並實際進行撒水分佈試驗對數據進行分析探討，針對國內密閉式撒水頭認可基準相關條文上提出建議對策，供消防署及業界規範修訂及產品改善之參考。經分析比較，國內密閉式撒水頭認可基準與日本之規範(閉鎖型撒水頭檢定細則)較為相近，而與UL 199(Automatic Sprinklers for Fire-Protection Service 消防用自動撒水頭)則在材質試驗、腐蝕試驗、玻璃球相關試驗、墊片(止水承座)及撒水分佈試驗等項目均有很大差異性存在。實際執行撒水分佈試驗，在10水盤及16水盤撒水分佈試驗時，國產品、日本進口品及UL認證品均可合格通過，但在實施米字型撒水分佈試驗(撒水半徑r2.3、試驗壓力1.0 kgf/cm2)時，UL認證品則無法通過測試，顯見基準在此項試驗仍無法適用於UL認證之產品。

Many difficult executions or inconsistencies between the sprinkler approval standard and the standard for installation of fire safety equipments based on use and occupancy have been in existence since sprinkler approval standard was published in 2001. Moreover, the sales for sprinklers and installations have been seriously affected by the application of it. The purpose of this research is to compare the national and international installations and inspection standards for sprinklers, and analyze the data of water distribution test. Accordingly, the recommendations and strategies could be made for the articles of sprinkler approval standard. In addition, to National Fire Agency (NFA) and related industry, these may be the references for amendments and improvement of sprinklers. The sprinkler approval standard in Taiwan is similar to the one in Japan through analysis. On the contrary, the related tests, including material test, corrosion test, glass-bulb test, incorporating polymeric gasket test and water distribution test, in the UL 199 （Automatic Sprinklers for Fire-Protection Service）have considerable discrepancies to the standards in Taiwan. When 10 pan and 16 pan distribution tests are done respectively, the result shows that the sprinklers produced in Taiwan, Japan and as UL listed products are acceptable. Nevertheless, the when the water distribution test in accordance with Japan’s standard （the effective sprinkler radius is 2.3 meters and the test pressure is 1 kgf/cm2） is conducted, the UL listed products are unable to meet with the standard. Obviously, this water distribution test in sprinkler approval standard is not feasible to the UL listed products.
