石油及石油产品.阻燃液乳化稳定性的测定.第2部分:HFB类流体ISO 20783-2-2003

[中文适用范围]： 本部分ISO 20783规定了三种测试方法，用于评估ISO 6743-4中定义的HFB类别内乳液的稳定性。方法A描述了在环境温度（20±2）°C下储存期间测定稳定性的方法，适用于HFB和HFB.LT流体。方法B描述了在中等温度（70±2）°C下储存期间测定稳定性的方法，同样适用于HFB和HFB.LT流体。方法C描述了在低温（-10±2）°C下储存期间测定稳定性的方法，仅适用于HFB.LT流体。 [外文原描述]： ISO 20783-2:2003 specifies three test methods to assess the stability of emulsions within the category HFB, as defined in ISO 6743-4. Method A describes a method for the determination of stability during storage at ambient temperature [(20 ± 2) °C] and is applicable to HFB and HFB.LT fluids. Method B describes a method for the determination of stability during storage at medium temperature [(70 ± 2) °C] and is again applicable to HFB and HFB.LT fluids. Method C describes a method for the determination of stability during storage at low temperature [(-10 ± 2) °C] and is applicable only to HFB.LT fluids.
