ISO Standards
Hydraulic hose construction and performance is covered by various national and international standards including ISO, BSI, SAE, DIN, API, and CETOP. Most proprietary hoses conform to one standard or another, the SAE standards being the most widely followed in the U.S. SAE standards provide general, dimensional, and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment.
SAE is based on construction technique and material of hydraulic hose. The various application parameters required when selecting hose are size, temperature, fluid type, and pressure, to name a few. Depending on these criteria, the choice of hose construction will change to suit the conditions.
Each of the hydraulic hose styles summarized in the table must meet a set of dimensional and performance characteristics as set forth by SAE, and they are designated as 100R1 through 100R19. However, SAE issues no approval source lists, certification, or letters of approval. Adopting these standards by manufacturers is strictly voluntary. Therefore, SAE standards only ensure a similarity of hoses among different manufacturers, and most manufacturers offer hoses that far exceed SAE standards.
