《GB/T 12722-2008橡胶和塑料软管组合件 液压脉冲曲挠试验(半Ω试验)》由TC35(全国橡胶与橡胶制品标准化技术委员会)归口,TC35SC1(全国橡胶与橡胶制品标准化技术委员会软管分会)执行,主管部门为中国石油和化学工业联合会。
本标准代替GB/T12722―1991《橡胶和塑料软管组合件 屈挠液压脉冲试验(半Ω 试验)》。 本标准规定了脉冲试验过程中液压软管组合件以被称为“半Ω”的方式曲挠的一种方法。 本标准与GB/T12722―1991的主要差异如下:
―――修改了标准名称;
―――修改了对试样的要求(见第4章);
―――修改了试验流体温度(1991年版的5.1;本版的第5章);
―――修改了最小弯曲半径、软管外径的字母表示(见第4章);
―――在试验报告中增加了升压速率和试验流体(本版的第7章)。
Scope
WARNING—Personnel using this standard should be familiar with normal laboratory practice. This standard does not intend to address all safety issues that may arise from the use of this standard. It is the user's responsibility to establish appropriate safety and health regimes and ensure compliance with national regulations. This standard specifies a method by which hydraulic hose assemblies flex in what is known as a "half omega" during an impulse test.
