ASABE to Develop Standard for Hermetic Grain-Storage Bags

ST JOSEPH, MICHIGAN— The American Society of Agricultural and Biological Engineers (ASABE) has initiated a project to develop a standard for the testing and performance of hermetic bags used for grain storage. 

X657, Measurement and Rating of Hermetic Storage Bags—Specifications of Gas Barrier Liners, will specify the key engineering properties used in measuring and rating gas tightness—hermeticity—and strength of gas barrier liners.

Several brands of hermetic storage bags have become available commercially in Central America, Sub-Saharan Africa, and South and Southeast Asia. Manufacturers and distributors make competing claims, often not supported by scientific data, about the performance of their products, including their hermeticity and their effectiveness in controlling biological activity. X657 will provide a common international approach for specifying the critical performance parameters, as well as for testing the performance and strength of the bags and rating liner hermeticity.

Anyone interested in participating in the development of this standard may contact Jean Walsh ( for more information.

ASABE is recognized worldwide as a standards developing organization for food, agricultural, and biological systems, with more than 280 standards currently in publication. Conformance to ASABE standards is voluntary, except where required by state, provincial, or other governmental requirements, and the documents are developed by consensus in accordance with procedures approved by the American National Standards Institute.
