All castings manufactured by US Foundry are proof load tested in accordance with the destructive testing protocol below, and are assigned one of the following four load rating designations Non Traffic These castings are intended for areas such as sidewalks, terraces, and other areas not subject to vehicular traffic loads. Medium Duty Castings bearing this designation are able to withstand occasional vehicular loading, but are not intended to receive heavy highway traffic. Applications include driveways, parking lots, and ramps. Just two weeks ago we hosted my parents, siblings, their spouses, and their children for Thanksgiving.

Extra Heavy Duty For traffic applications requiring even greater load bearing capability, or where increased safety factors are necessary. When castings in this load rating designation are required, please advise loading conditions including total wheel load, tire contact area and tire pressure. Designation. Load Application.

Call Center Crack Load' title='Call Center Crack Load' />This testing procedure is detailed in Federal Specification CID A A 6. Medical Billing Training Manuals. AASHTO M 3. 06. The fundamentals aspects of the test are A specified load is applied over a 9 x 9 contact area at the center of the casting. The load is held for a period of 1 minute. The cover, grating or frame is inspected for cracks or permanent deformation. Any crack or detrimental permanent deformation will cause the castings to be rejected. Most tests are performed with loads greater than those specified, even to destruction. Referenced Specifications. There are several published specifications that are available to assist designers in specifying iron castings. It is the responsibility of the designer to determine if one or all of these specifications are appropriate for a given application. These specifications are referenced as follows Federal Specification CID A A 6. Frames, covers, gratings, steps, sump and catch basin manhole ASTM A 4.
