SAE J343:2001 pdf download Test and Test Procedures for SAE 100R Series Hydraulic Hose and Hose Assemblies
1. Scope—This SAE Standard gives methods for testing and evaluating performance of the SAE 100R series of hydraulic hose and hose assemblies (hose and attached end fittings) used in hydraulic fluid power systems.Specific tests and performance criteria for evaluating hose assemblies used in hydraulic service are inaccordance with the requirements for hose in the respective specifications of SAEJ517.
This document further establishes a uniform means of testing and evaluating performance of hydraulic hoseassemblies.
2.1Applicable Publications—The following publications form a part of the specification to the extent specified herein. Unless otherwise indicated, the latest revision of SAE publications shall apply.
2.1.1 SAE PUBLICATION—Available from SAE,400 Commonwealth Drive, Warrendale, PA 15096-0001.
SAE J517—Hydraulic Hose
2.1.2 ASTM PUBLICATIONS—Available from ASTM,100 Barr Harbor Drive, West Conshohocken, PA 19428-2959.
ASTM D 380—Standard Methods of Testing Rubber Hose
2.1.3 ISO PUBLICATIONS—Available from ANSI,11 West 42nd Street, New York, NY 10036-8002.
ISO 3448—Industrial liquid lubricants—ISO viscosity classification
ISO 6605——Hydraulic fluid power—Hose assemblies—Method of test
3. Test Procedures—The test procedures described in the current issue of ASTM D 380 shall be followed. However, in cases of conflict between the ASTM specifications and those described as follows, the latter shall take precedence. Unless otherwise specified in this document, or other SAE standards, tests shall be conducted at the prevailing ambient temperature of the testing facility.
4. Standard Tests WARNING—Water or another liquid suitable for the hose under test shall be used as the test medium. The use of air and other gaseous materials as testing media should be avoided because of the risk to operators. In special cases where such media are required for the tests, strict safety measures are imperative. Furthermore, it is stressed that when a liquid is used as the test medium, it is essential that all air is expelled from the test piece because of the risk of injury to the operator due to the sudden expansion of trapped air released when the hose bursts.
4.1 Dimensional Check Test—The hose shall be inspected for conformity to all dimensions tabulated in the applicable specification.
Determine finished outside diameters and reinforcement diameters, where required, by calculation from measurement of the respective circumference.
As an alternative, use a flexible tape graduated to read the diameter directly.
Measure the inside diameter by means of a suitable expanding ball or telescoping gage.
Measure concentricity over both the reinforcement and the finished outside diameters using either a dial indicator gage or a micrometer.
Round the foot of the measuring instrument to conform to the inside diameter of the hose.
