20、rd ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technic
21、al committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of el
22、ectrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard require
23、s approval by at least 75 % of the member bodies casting a vote. International Standard ISO 13226 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Physical and degradation tests. Annexes A to N form a normative part of this International Standard. License

27、NDARD ISO 13226:1999(E) 1 Rubber Standard reference elastomers (SREs) for characterizing the effect of liquids on vulcanized rubbers WARNING Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety probl
28、ems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies requirements for vulcanized rubbers in sheet form for use as
29、 standards in characterizing the effect of test liquids and service fluids. Details of the individual standard reference elastomers are listed in the annexes. The compounding and preparation ensure that the property profile agrees sufficiently with that of the material group represented, while the s
30、imple formulation ensures reliable reproducibility. The specified property changes of the SRE when in contact with a fluid under specified conditions may be included as supplementary data in specifications for the fluid concerned. This International Standard is not designed to provide formulations o
31、f elastomeric-product compositions for actual service. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of thes
32、e publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referre

All ingredie
37、nts shall be of recognized rubber quality. The identification of proprietary materials as suitable ingredients does not exclude the use of other materials that can be shown to meet the requirements of the standard. If necessary, the quantity of carbon black or silica may be adjusted from one consign
38、ment of rubber to another to give properties within the limits specified in the annexes. If the filler content is adjusted, the details shall be declared. 4 Preparation The mixing of compounds and the vulcanization of test sheets shall be carried out in accordance with ISO 2393 as modified by detail
39、ed conditions and procedures given in the annexes. If a mould release agent is needed, dry PTFE mould lubricant shall be used. 5 Description The vulcanized test sheets shall be 2 mm 0,2 mm thick when measured in accordance with ISO 4648, free from surface defects and from internal voids when viewed
40、with normally corrected vision. A “lot“ of sheets is those sheets made from a single batch of rubber mix vulcanized under the same conditions. A “pressing“ is the quantity of sheets produced at the same time in a single moulding operation. 6 Test sheet properties The test sheets shall be characteriz
41、ed by one or more physical properties in accordance with the relevant ISO standard test method. Properties and tolerances for individual materials are given in the annexes. All sheets shall be tested for compliance with the requirements of clause 5. A sample sheet from each lot shall be tested for t
42、he properties of interest for compliance with the tolerances given in the appropriate annex. The actual values obtained shall be reported. The test pieces necessary for determining material properties shall be taken from the test sheets in such a way that a minimum distance from the edge of the shee
43、ts is maintained. Bar-shaped test pieces shall be taken with their longitudinal axis parallel to the direction of milling of the moulding blank. 7 Designation Each elastomer shall be designated as ISO 13226 SRE-A/B where ISO 13226 is this International Standard, SRE is the abbreviation for standard
44、reference elastomer and, after the hyphen, A is set of code-letters designating the polymer type and B is a descriptor identifying the particular compound. Some designations end with the letter X to signify that additional test requirements apply. 8 Storage Test sheets shall be stored in accordance
45、with ISO 2230. After one year, they shall be retested or disposed of. If the sheets still meet the test requirements, they may be stored and used for a further year.

46、 (normative) Acrylic rubbers: SRE-ACM/1 and SRE-ACM/1X A.1 Purpose These SREs are representative of ACM materials such as are used, for instance, for parts in contact with petroleum products in the mechanical-engineering and automobile sectors. They are used for the characterization of service fluid
47、s such as mineral oils, fuels, lubricants, hydraulic fluids, coolants and refrigerants with regard to their effect on vulcanized acrylic rubbers. The changes in mass, volume, hardness, tensile strength and elongation at break of the SRE when in contact with the service fluid under specified conditio
