| Contact with liquid and semi-solid materials Elastomeric seals should not be allowed to come into contact with solvents, oils, greases or any other semi-solid materials at any time during storage, unless so packed by the manufacturer. Contact with metal and non-metals Direct contact with certain metals, e.g. manganese, iron and particularly copper and its alloys, e.g. brass and compoundsofthese materialsare knowntohave deleterious effects on some rubbers. Elastomeric seals should not be stored in contact with such metals. Because of possible transfer of plasticisers or other ingredients, rubbers must not be stored in contact with PVC. Different rubbers should preferably be separated from each other. Cleaning Where necessary, cleaning should be carried out with the aid of soap and water or methylated spirits. Water should not, however, be permitted to come into contact with fabric reinforced components, bonded seals (because of corrosion) or polyurethane rubbers. Disinfectants or other organic solvents as well as sharp-edged objects must not be used. The articles should be dried at room temperature and not placed near a source of heat. She/f life and shelf life control The useful life of a elastomeric seals will depend to a large extend on the type of rubber. When stored under the recommended conditions (above sections) the below given shelf life of several materials should be considered. | ||||||||||||||||||||||||||||||||||||||||||||||||

| Elastomeric seals should be inspected after the given period. After this giving an extension period is possible. Rubber details and components less than 1.5 mm thick are liable to be more seriously affected by oxidation degradation even when stored in satisfactory conditions as recommended. Therefore they may be inspected and tested more frequently than it is mentioned above. Rubber details I seals in assembled components It is recommended that the units should be exercised at least every six months and that the maximum period a rubber detail be allowed to remain assembled within a stored unit, without inspection, be a total of the initial period stated above and the extension period. Naturally this will depend on the design of the unit concerned. | ||||||||||||||||||||||||||||||||||||||||||||||||
