The following MT-MECH modules have been revisioned:
The major improuvements concern the MT-COMP program where a complete new national code (AD-MERBLATT - Germany) has been included and local loads can now be verified using BS.5500 App.G, WRC107, WRC297.

26.The local loads analysis according to WRC 107 and WRC 297 has been added to the program.
27.The function "save" has been added to the Audit Report datasheet. This function allows the user to save the datasheets as zip files that can be in a second time unzipped and viewed with any drawing program allowing bit map drawings like Paint.
28.The calculation of the maximum working pressure for the hydraulic test condition with corroded thicknesses has been added to the program.
29.Some minor bugs have been fixed.
