    CHETAH 11.0

    CHETAH 11.0 was released March 2020. Those who wish to upgrade from older versions of CHETAH (10.0 or lower) to CHETAH 11.0 should contact ASTM International (see https://www.astm.org/BOOKSTORE/PUBS/chetah_intro.htm to purchase an upgrade).

    Please note that CHETAH 11.0 is a complex scientific database program. Depending on the speed and condition of your computer, calculations may take some time. For example, a typical time for a five-component mixture flammability calculation on a midrange 32-bit computer is 40 seconds. Simpler calculations on the same computer may appear to be instantaneous. Efforts are being made to speed up calculations and when progress is made a service pack will be issued and made available on this web page.

    Service packs may be issued from time to time to address issues that emerge and to enhance user experiences. Note that the installation of any service pack will require an Administrator level user account, as did the initial installation of CHETAH 11.0

    All Service Packs are cumulative and will include fixes for issues discovered and corrected since the initial CHETAH release and since the last Service Pack release and will be available to ALL users at no charge.
