    適用范圍
    (a) This Standard covers manually operated thermoplastic valves in nominal valve sizes 1∕2 through 12. These valves are intended for use below ground in thermoplastic fuel gas distribution mains and service lines. The maximum operating pressure (MOP) at which such distribution piping systems may be operated is in accordance with Transportation of Natural and Other Gas by Pipeline; Minimum Safety Standards [49 C.F.R., §192 (2017)] for temperature ranges of ?20°F to 140°F (?29°C to 60°C). (b) This Standard sets qualification requirements for each basic valve design as a necessary condition for demonstrating conformance to this Standard. (c) This Standard sets requirements for newly manufactured valves for use in below-ground piping systems for fuel gas [includes synthetic natural gas (SNG)] and liquefied petroleum (LP) gases (distributed as a vapor, with or without the admixture of air) or mixtures thereof. (a) 本標準涵蓋標稱閥門尺寸為1∕2至12的手動熱塑性閥門。這些閥門旨在用于熱塑性燃氣分配干管和服務管線的地下。此類分配管道系統可操作的最大工作壓力 (MOP) 符合管道輸送天然氣和其他氣體;最低安全標準 [49 C.F.R., §192 (2017)] 適用于 ?20°F 至 140°F(?29°C 至 60°C)溫度范圍。 (b)本標準規定了每種基本閥門設計的資格要求,作為證明符合本標準的必要條件。 (c)本標準規定了用于燃氣[包括合成天然氣(SNG)]和液化石油(LP)氣體(以蒸汽形式分布,有或沒有空氣混合物)或其混合物的地下管道系統中使用的新制造的閥門的要求。
