Which specification type is recognized for specifying a brand of marker board material?

The correct choice in this context is the proprietary specification. This type of specification is utilized when a specific product or brand is desired for a project. By using a proprietary specification, the project specifies particular brands or models, which helps ensure that the specific qualities, performance, and aesthetic attributes of those products are met within the project scope. This is particularly important in applications such as marker board materials, where the functionality and appearance are critical for the intended use.

In contrast, performance specifications outline the required performance criteria without naming specific brands, allowing for a wider selection of products that meet those criteria. Descriptive specifications provide detailed descriptions of the materials, products, and workmanship required without suggesting a particular brand, focusing instead on the characteristics of the items to be used. General specifications set forth broad guidelines and standards but do not detail specific materials or brands. Thus, proprietary specifications are the most fitting choice for indicating a specific brand of marker board material.
