MATERIAL SUBSTITUTION PROHIBITION Sample Clauses
The Material Substitution Prohibition clause prevents parties from replacing specified materials with alternatives during the performance of a contract. In practice, this means that contractors or suppliers must use the exact materials identified in the agreement and cannot switch to different brands, grades, or types without prior written approval from the other party. This clause ensures that the quality, safety, and performance standards agreed upon are maintained, thereby reducing the risk of disputes or failures due to unauthorized material changes.

MATERIAL SUBSTITUTION PROHIBITION. There shall be no substitutions of like or similar goods without written authorization by an authorized representative from Crystal Group. Unauthorized material substitution includes any deviation from the engineering definition of a raw material. Engineering definition includes Buyer design drawing and applicable specifications, product specification, form, size, shape, chemistry, melt method, origin, temper/condition, product testing or surface finish. Alternate materials specified in the engineering definition (and often described as approved material substitutions therein) do not constitute unauthorized material substitution. Unless specifically authorized by the engineering definition, conversion of a raw material (i.e. heat treat to change the temper or condition of the material) constitutes material substitution of the condition provided by the manufacturer and shall not be done with authorization from Crystal Group. Buyer’s engineering drawings may refer to obsolete or superseded specifications covering several forms, thicknesses, widths, etc. of the alloy or alloys. The required characteristics of these materials are defined not only by the objective test standards of the specification, but by the processes/methods by which this final form is achieved. These requirements are often captured in the definitions of the required material forms, and may not be explicitly called out in the detailed requirements. The raw material certification results from both the process used to make it and the tests to verify basic properties. Seller shall ensure that metallic materials covered by current or obsolete/superseded specifications are produced using the standard industry practices designed strictly for the production of stock to the specified thickness, diameter, width or cross sectional 12 area, achieved by thermo-mechanical processing or casting process. Chemical, electrochemical and mechanical methods used for the removal of surface scale or contamination, or the production of the required surface finish, in accordance with the material specification are acceptable. Raw material must not be re-certified with respect to thickness, diameter, width or cross sectional area or product form. Machining or cutting of thicker product or other product forms shall not be supplied in lieu of specified product unless specifically authorized by Buyer. Raw material certifications for material or parts shall reflect the form and size of the raw material as originally ma...
