Foreword

This standard and ISO 12922.1999 "Lubricants, industrial oils and related products (L class) -H (Hydraulic systems) -HFAE, HFAS, HFB, HFC, HFDR and HFDU variety of specifications "(in English) of non-equivalent. This standard and ISO 12922.1999 HFC basically the same technical requirements. This standard and ISO 12922. The main technical differences HFC 1999 as follows. --- Increasing the kinematic viscosity range of values \u200b\u200b40 ℃; --- Increase the pour point indicators "Report"; --- PH values \u200b\u200bfrom 6.7 to 8.0 to 11.0 to 11.0; --- Aging characteristics defined as "index value is determined by the providers and users of negotiation"; --- Vane pump test unspecified. This standard by the National Standardization Technical Committee on Petroleum Products and Lubricants made. The standard by the China Research Institute of Petroleum Corp. petrochemicals. This standard was drafted. China Petroleum & Chemical Corporation Research Institute of Petroleum. The main drafters of this standard. Chen Liqing. This standard is the first release. Water - glycol type fire-resistant hydraulic fluid

1 Scope

This standard specifies the water and glycol (include ethylene glycol, diethylene glycol, propylene glycol, etc.) as a base component, add anti-wear agent, an oiliness agent, Antirust additives made of water - glycol type fire-resistant hydraulic fluids - Requirements and test methods, inspection rules and signs, packaging, transportation And storage.
