Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Ports with truncated housing for O-ring seal. If it is less than 4 mm, then the micro test procedure shall be used. Therefore, the fact that seals pass, is no guarantee of zero leakage in service.
The result shall be the specified nominal density see 4. Unless otherwise specified, no part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from either ISO at the address below or ISO’s member body in the country of the requester.
Similarly, a designed interference fit between the outside diameter of the seal, and the diameter of the housing bore, retains the seal and prevents static leakage. Compliance with a British Standard cannot confer immunity from legal obligations.
The materials used for tests shall be in an unused condition. The work of preparing International Standards is normally carried out through ISO technical committees. Dimensions, design, test methods and requirements for external and internal hex port plugs. ISO shall not be held responsible for identifying any or all such patent rights.
Leakage nicks, notches or rips in the lip scratches or notches on the shaft surface examine the quality of the rings – pt. In downloading this file, parties accept therein the responsibility of not infringing Adobe’s licensing policy.
NOTE Seal isp can be influenced by operating and environmental conditions beyond the scope of this test. Scratches on the external diameter of the sealing too rough surface of the casing opening make an opening in the casing with the correct roughness sharp edge of the casing opening make a bevel in the opening.

Ensure that the batch of elastomer has been tested in accordance with Clause 7. This part of ISO specifies general test requirements for rotary shaft lip-type seals. We would be grateful if anyone finding an inaccuracy or ambiguity while using iiso British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. Detailed questions should be directed to the Manufacturer.
It is the constant aim of BSI to improve the quality of our products and services. They may not be used as a basis for civil legal claims. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. Avoid unnecessary stretching of the spring during installation. Table 1 — Standard shaft and housing dimensions Dimensions in millimetres Isso diameter Housing diameter Seal width D1 D2 b 20 35 7 40 55 8 60 80 8 90 12 15 The test apparatus shall also conform to the following additional requirements.
Dull sharp edges decreased opening diameter check the dimensions 6. Careful storage, handling and proper installation of all seals are necessary to avoid hazards, both prior to and during 6194–2, which would adversely affect service life. Where the seal is required for the low-temperature stiffness test, ensure that the seal manufacturer has also stated the maximum modulus after test at the selected test temperature.
Due to their very wide application in many branches of industry, rings sealing rotation shafts have required well-developed standardisation with regard to the dimensions, materials, types. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service.

The housing and the rotating member shall be capable of reproducing the eccentricity and off-set specified in 4. Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing.
BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. Search on our website. Find the desired size.
Revisions British Standards are updated by amendment or revision. Inspect the seal lip, noting any cracks, tears, splits or any imperfections that may have appeared as a result of the test. This study provides primarily information on this matter, which will enable the user to move in the maze of materials and catalogues of individual manufacturers.
For details of these and other benefits contact Membership Administration. It presents the UK view on standards in Europe and at the international level. Users of British Standards should make sure that they possess the latest amendments or editions. The size selected shall be that nearest to the application size. The test specimens shall be similar to those used for the hardness test see 7.
The tests may be used for qualification purposes. The Manufacturer reserves the right to introduce changes, according to new technical solutions and progress in the area of technologies and materials. In order to ensure that the material used for production seals does not vary significantly from that of the dynamic-test seals, subsequent production batches shall also be tested on a random sample basis.
