Does the content convey the same meaning without hearing a description of the image/icon?
If you answered Yes to either of these questions, then your image/icon is decorative. Alternative text is not required.
If you answered No, then you must consider creating alternative text or a meaningful label for the image/icon.
Taking It One Step Further
Even if you answered “yes” to the question of whether the image is decorative, you may be missing out on an opportunity. If you are working with or are in fact a diligent designer, you are including images that convey a distinct message or convey a mood. If your image falls into this category, please consider the intention of the image. Many times, content producers who are new to this type of work will merely describe the literal composition of an image, and though this may meet the technical requirement, it misses the purpose of providing the descriptions.

If you feel that the description needs ore detail, you may need to consider using a long description element or an alternative technique for providing the detailed information.
