If it is less than 4 mm, then the micro test procedure shall be used. This part of ISO specifies general test requirements for rotary shaft lip-type seals. Details of the software products used to create this Sio file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing.
We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent isoo.
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.
Excessive wear or hardening of the lip pressure deaerate the sealing chamber no grease supply grease to the ring improperly selected material for a particular factor change the ring material 4.
ISO – Standards Australia
The main task of technical committees is to prepare International Standards. The surroundings of the company. The test specimens shall be similar to those used for the hardness test see 7. Damaged sealing body incorrect installation use proper installation methods careless handling during transport and storage, the rings should be packed ios.
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. Shaft wear filings and other impurities clean the elements before the installation.
It is the responsibility of the user of this part 6194–2 ISO to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. Performance test procedures  ISO In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below.
ISO consists of the following parts, under the general title Rotary shaft lip-type seals incorporating elastomeric sealing elements: NOTE Seal performance can be influenced by operating and environmental conditions beyond the scope of this test. Compliance with a British Standard cannot confer immunity from legal obligations.
Whilst this part of ISO does not purport to address all the safety problems, if any, associated with its application, attention is drawn to the need to employ sensible precautions while handling hot and cold fluids and equipment. Find the desired size. Except as permitted under the Copyright, Designs and Patents Act no extract may be reproduced, stored in a retrieval system or transmitted in any form or by any means — electronic, photocopying, recording or otherwise — without prior written permission from BSI.
If the dimension of the test piece is greater than 4 mm, then the normal test procedure shall be used. Avoid unnecessary stretching of the spring during installation careless handling protect the rings during transport and storage 8. Dry-heat ageing in air Time: In dusty atmosphere, use a dustproof lip.
Do not blot dry. Storage, handling and installation  ISO io Ports with truncated housing for O-ring seal. Various BSI electronic information services are also available which give details on all its products and services. Nominal dimensions and tolerances  ISO It is incorporated by Royal Charter.
This publication does not purport to include all the necessary provisions of a contract. The result shall be the specified nominal hardness see 4.
Information on standards BSI iao a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. This third edition cancels and replaces the second edition ISO The size selected shall be that nearest to the application size. In accordance with Adobe’s is policy, this file may be printed or viewed but shall not be edited unless the typefaces which are embedded are licensed to and installed on the computer performing the editing.
It is the 61942 aim of BSI to improve the quality of our products and services. At ambient or elevated temperatures ISORubber, vulcanized or thermoplastic — Determination of compression set — Part 2: Dull sharp edges decreased opening diameter check the dimensions 6. It presents 61994-2 UK view on standards in Europe and at the international level. Ensure that the batch of elastomer has been tested in accordance with Clause 7. Dimensions, design, test methods and requirements for external and internal hex port plugs.
The test shaft and seal housing shall simulate the envisaged maximum eccentricities specified by the customer.
An example of a seal test report for the dynamic low-temperature test is shown in Annex B. Damaged spring incorrect installation use proper installation methods. Inspect 6149-2 seal lip, noting any cracks, tears, splits or any imperfections that may have appeared as a result of the test.
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.
