Hoses tested to higher impulse standards are likely to have a longer hose life, which is why many users are switching to ISO standards. Strict testing requirements allow users to know exactly what the hose is rated for and how it should perform while on hydraulic equipment. The ISO 18752 standard makes it easy for end users and engineers to identify what hose should be used on a certain piece of equipment or machinery. ISO Benefits to End Customers and Engineers Pressure pulses are also applied at an elevated value to stress the spiral wires and end fittings for a minimum number of required cycles. In this accelerated test, the hose is positioned into a U shape on a test stand, and the fluid is raised to the specified working pressure. This requirement is the toughest of all grades and classes to achieve, and specifies meeting 248вЏ temperature and an impulse pressure of 133% of maximum working pressure for at least one million impulse cycles. This specification also requires spiral hose to exceed one million pressure impulse cycles according to ISO 18752 hose grade D, type DC. The primary concept behind ISO Standard 18752 requires constant pressure performance ratings in each class for different hose sizes. The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components. It is limited to the performance of hoses and hose assemblies. It is important to note that ISO 18752:2014 does not include requirements for the connection ends.

Additionally, the grade is then classified by the outside diameter (O.D.) of the hose into standard types (AS, BS, CS) or compact types (AC, BC, CC, DC). Each grade requires a specific number of impulse cycles at a certain temperature and impulse pressure in order to meet the standard. Hydraulic hoses meeting ISO 18752 specifications are classified according to their resistance to impulse pressure in four grades: A, B, C, and D. The ISO 18752 Standard has nine pressure classes for maximum working pressure, ranging from 500 to 8,000 psi. ISO Standard 18752, released in 2006, takes a different approach centered around the design practices of users who typically design hydraulic systems based on performance and pressure requirements.

Many large OEMs switched to ISO standards in their design and manufacturing process to ensure the sale and service of their equipment globally. More recently, however, hydraulic system designers began adopting ISO specifications. SAE established minimum pressure ratings for various hose IDs (inside diameters) and were later revised to also include constant-pressure hoses, such as R13, R15, R17 and R19, which are hoses that maintain pressure ratings within a group regardless of size. These manufacturer-driven SAE standards have been based on design, construction, and pressure ratings to ensure that hydraulic hoses meet minimum construction requirements.

Why are there different hydraulic hose standards and what do they mean for you and your application? For decades, SAE J517 has published guidelines for 100R1 through 100R12 series hydraulic hoses.
