Scope

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.
