Q&A
Q:What are the representative hydraulic oil specifications in European and American countries?
A:German DIN 51524-2-1985 (HM level), DIN 51524-2-1990 (HV level); The French national standard NFE48-603-1983 includes HH, HL, HM, and HV; the American company Denison specifies that HF-1 is an oxygen resistant and rust resistant HL type, and HF-2 and HF-0 are HM wear-resistant types. The HF-0 specification places higher requirements on hydrolysis stability and oxidation corrosion resistance, and also adds tests for thermal stability, filtration, high-pressure vane pumps, and high-pressure plunger pumps, representing the highest level of hydraulic oil products internationally. The specifications of Cincinnati Milacron Company in the United States include P-38, P-55, and P-57 as oxygen resistant and rust resistant HL types, P-68 (ISO32), P-69 (ISO46), and P-70 (ISO68) as wear-resistant HM types, and P-75A, P-75B, and P-75C as wear-resistant special types. The specifications of Vickers in the United States mainly include two types of anti-wear hydraulic oil: Vickers M-2950-S (35VQ25t) and Vickers I-286-s (V-104C). The ISO/TC28/SC4 Technical Committee of the International Organization for Standardization has issued ISO 11158-1997 (including HL, HM, HG, HV, HS) standards for mineral oil and synthetic hydrocarbon hydraulic oil products, as well as ISO 12922-1999 standards for flame-retardant hydraulic fluids and ISO 15380-2000 standards for environmentally acceptable hydraulic oil products.
