What is ASTM
ASTM International positively impacts public health and safety, consumer confidence, and overall quality of life. They integrate consensus standards – developed with their international membership of volunteer technical experts – and innovative services to improve lives… helping our world work better.
The American Society for Testing and Materials was formed in 1898, founded by Charles B. Dudley, Ph.D., a chemist with the Pennsylvania Railroad. In 2001, they changed our name to ASTM International.
What is OMRI?
OMRI supports organic integrity by developing clear information and guidance about materials, so that producers know which products are appropriate for organic operations. OMRI is a 501(c)(3) nonprofit organization that provides an independent review of products, such as fertilizers, pest controls, livestock health care products, and numerous other inputs that are intended for use in certified organic production and processing. When companies apply, OMRI reviews their products against the organic standards. Acceptable products are OMRI Listed® and appear on the OMRI Products Lists©. OMRI also provides technical support and training for professionals in the organic industry.
