Rubber — Compatibility between hydraulic fluids and standard elastomeric materials

Edition date: 2011-11-29
In Force
Available languages: English, French
Summary:

ISO 6072:2011 specifies test methods for evaluating the effect of hydraulic fluids on standard elastomeric materials that have been manufactured in accordance with specified processes. It allows baseline comparisons of fluids with standard elastomers.

The standard provides formulations, mixing procedures and vulcanization procedures for five types of elastomeric composition: acrylonitrile-butadiene rubbers (NBR 1 and NBR 2), fluorocarbon rubber (FKM 2), ethylene propylene diene rubber (EPDM 1) and hydrogenated acrylonitrile-butadiene rubber (HNBR 1).

These procedures evaluate the effect of mineral-based, fire-resistant and biodegradable hydraulic fluids on such compositions by measurement, under controlled conditions, of physical properties of standard test pieces of the elastomer before and after immersion in the fluids.

The standard does not provide formulations of elastomeric materials for actual service, although service elastomers may be tested using these compatibility procedures if required.



L'ISO 6072:2011 spécifie des méthodes d'essai pour l'évaluation de l'effet des fluides hydrauliques sur des matériaux élastomères de référence fabriqués par des procédés spécifiés, permettant d'établir des comparaisons de base de fluides avec des élastomères de référence.

L'ISO 6072:2011 donne les formulations et les modes opératoires de mélangeage et de vulcanisation de cinq types de caoutchoucs: a) caoutchoucs butadiène-nitrile acrylique (NBR 1 et NBR 2); b) caoutchouc fluoré (FKM 2); c) caoutchouc éthylène-propylène-diène (EPDM 1); d) caoutchouc butadiène-nitrile acrylique hydrogéné (HNBR 1).

Ces modes opératoires évaluent l'effet des huiles minérales, des fluides hydrauliques difficilement inflammables et des fluides hydrauliques biodégradables sur ces mélanges en mesurant, dans des conditions d'essai contrôlées, les propriétés physiques d'éprouvettes de référence d'un élastomère avant et après immersion dans les fluides.

L'ISO 6072:2011 ne fournit pas les formulations des matériaux élastomères pour service réel, bien que des élastomères en service puissent être, si besoin, soumis à essai selon ces modes opératoires de compatibilité.

  • In addition, you can request the rules of the rest of the organizations through the e-mail normas@aenor.com
  • Technical books on paper and in electronic format (PDF, epub).

The standards can be purchased in PDF, reading or paper. The reading standards are not download files, they can only be viewed in the client area. The standards ordered on paper and some of the books in the catalogue are printed on demand. 

Check deadlines in normas@aenor.com.

The license of use is for one user and one device, if you want to reproduce the content of the standard, you must request a license that will have an additional cost. Send us your inquiry here 

The AENOR standards and books that appear in the online store can only be purchased exclusively through the website. AENOR does not have a physical store.

Purchase procedure: by clicking on "Buy" the desired products will go to the shopping cart. If there are display problems, the recommended browser is Chrome.

To formalize the purchase you must access the customer area. If you are not registered as a customer, you must fill in a form with the data along with a password and username. This will create the account.

Once the "Customer data" form has been completed, "Order in progress" will be displayed with all the items loaded in the shopping cart, their prices, taxes established in current legislation and shipping costs if applicable.

The prices of the standards and books that appear in the various sections do not include taxes or shipping costs.

AENOR promotional codes consist of alphanumeric characters and can only be applied to online purchases, received through a specific offer and for a limited time. To apply your promotional code, you just have to enter it in step 2 of 4 of the purchase process on the website and click on "apply", after you have identified yourself and chosen the payment methods. Promo codes are not cumulative.

  • The purchase invoice can be downloaded from the customer area, in my previous orders

In the case of clients of companies based abroad, the taxpayer identification number of the corresponding country (for example, in Argentina the CUIT), must be filled in the CIF/NIF - VAT field .

  • Direct download via the website in the Customer Area. In the customer area, which can only be accessed with a password and username, the products purchased will be available for a period of fifteen days from the date of purchase, as long as the payment has been accepted. Files in digital format are protected and in no case editable. Before purchasing them, it is important that the license of use is read and accepted as a prior step to purchase.
  • Shipping by courier. Products purchased on physical media are shipped by courier. The maximum delivery time in Spanish territory, from the acceptance of the order by AENOR, is:
  •  Approximately seven working days for all standards purchased through the store in paper format.
  • Approximately three days for books purchased through the store. Stocks of paper books are limited and their offer on the website does not imply availability within the indicated period. In the event that the requested book is not available, the customer is notified of the delay in receiving the order, which will be approximately seven working days. 

For the rest of the products that are not on the website, check availability and delivery time at normas@aenor.com.
