GB/T 19699-2005 in English

《GB/T 19699-2005船舶与海上技术 货油舱压力/真空阀》由TC137（全国船用机械标准化技术委员会）归口，主管部门为国家标准化管理委员会
本标准规定了压力/真空阀的性能与试验的最低要求，强调了安装在液货船货油舱(见附录A)中的压力/真空阀的材料选择、内部加工和表面要求。本标准适用于当船舶系统(包括货油舱)中存在超出系统/舱设计参数的气体/蒸气压力或真空时起保护作用的压力/真空阀。

Scope

This standard specifies the minimum requirements for performance and testing of pressure/vacuum valves, emphasizing material selection, internal processing and surface requirements for pressure/vacuum valves installed in cargo oil tanks of tankers (see Appendix A). This standard applies to pressure/vacuum valves that protect when there is a gas/vapor pressure or vacuum that exceeds the system/tank design parameters in the ship's system (including cargo oil tanks). This standard does not deal with devices to prevent the entry of flames. In the "1997 International Convention for the Safety of Life at Sea (SOLAS)" of the International Maritime Organization (IMO), Article 59 ¹ of Chapter II-2 and IMO Maritime Safety Committee (MSC) Circular Letter No. 677 (MSC/Circ.677 ) "Revised Standards for the Design, Testing and Installation of Devices to Prevent the Entry of Flame into Cargo Tanks of Tankers". This standard specifies the design and daily operating guidelines, operating tests and maintenance requirements for pressure/vacuum valves.
