WIMA sponsors three certification programs to benefit its members and consumers. The ink, pencil and eraser certification programs ensure the products that carry the certification seals conform to ASTM Standard D4236, as well as all other state and federal regulations. For its members, WIMA retains a renowned toxicologist, Dr. Woodhall Stopford of Duke University Health Center, to review materials used, determine if any labeling is required, and report approval for use of the certification seal on that product.
