SAE J1273 PDF

It is subject to change to keep pace with experience and technical advances. For those new to hose use in a fluid-power system, this guide outlines practices to note during each phase of system design and use. Experienced designers and users skilled in achieving proper results, as well as the less experienced, can use this outline as a list of considerations to keep in mind. Fluid power systems are complex and require extensive knowledge of both system requirements and the various types of hose. Therefore, all-inclusive, detailed, step-by-step instructions are not practical and are beyond the scope of this document. Less experienced designers and users who need more information can consult specialists such as hose suppliers and manufacturers.

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 sudden expansion of trapped air released when sas hose bursts.

There shall be no leakage, hose burst or indication of failure below the specified minimum burst pressure. Brake hose testing is the most vital aspect of automotive manufacturing. Employs fluid compatible with hydraulic oils. In special cases where such media are required for the test, strict safety measures are imperative. We k been featured once again in Building Products magazine. Brake Hose Sar — Avoiding the recall trap. Subscribe here to the 4ward Testing newsletter to receive news, details of our latest solutions and special offers.

The 4ward Testing standards database provides a rapid method to identify the correct standards for your new product. Burst Test Hose Assemblies on which the end fittings have been attached less than 30 k shall be subjected to a hydrostatic pressure increased at a constant rate so as to attain the specified minimum burst pressure within a period of not less than 15 seconds no more than 30 seconds. With increased opportunities for libel action and demands for quality and value it is vital that the automotive industry follows strict standards for testing and quality assurance.

Server Error Proof Pressure Test This proof test is conducted at twice the working pressure of the hose unless otherwise specified by the customer. Hydraulic Test Stand, hydrostatic test stand, pressure testing and others please contact our sales rep. To receive additional information please contact a sales representative or click here send us an email.

The available Impulse test stands for hydraulic components are: There should be no indication of failure or leakage. Webinar available click here to get more info. Test Standards Need to find the right standards for your new product or solution? It can run flexing and rotating testing up to 20 Programmable wave points in accordance to the following norms: The use of air or other gaseous materials as testing media should be avoided because of the risk to operators.

It is recommend ed that proof and burst testing be performed in accordance with SAE J and SAE J or an applicable industry standard or customer specification. The hose assemblies to be bench tested must be inspected to ensure conformance to applicable test specifications. Customer defines its own test standard! The two most common models are: The SAE J standard gives methods for testing and evaluatinig the performance of the SAE R series hydraulic hose and hose assemblies hose and attached end fittings used in hydraulic systems.

The equipment has pre-set Square and Peak waveforms in accordance with customer defined or international standards, and on top of that the equipment has customized waveforms capability that allows the u to be programmed up to 20 points Pressure x Time.

Specific test and performance criteria for evaluating hose assemblies used in hydraulic service are in accordance with the requirements for hose in the respective specifications of SAE J Testing Hydraulic Hose Assemblies Coupled hose assembly lots should be sampled and tested utilizing an acceptable burst and proof pressure procedure.

Coupled hose assembly lots should be sampled and tested utilizing an acceptable burst and proof pressure procedure. These are even more powerful and delivery superior testing pressure to run your tests. Burst and fine jets can sar the skin. It is important to realize that, with the exception of proof test and change in length, all hose assemblies under pressure testing are to be destroyed after the test.

This proof test is conducted at twice the working pressure of the hose unless otherwise specified by the customer. BI HP with max test pressure up to 14, psi BI HP with max test pressure up to 21, psi BI HP with max test pressure up to 29, psi This equipment runs several types of waveforms based on your standard requirements; J waveform as: The test pressure shall be maintained for a period of not less than 30 seconds or more than 60 seconds.

It is recommended that every facility h hydraulic hose assemblies j34 a copy of the HS standards manual. Standards BS Part 1. Built and managed by. Related Articles.
