The word "shall" is used to indicate mandatory requirements to conform to the standard. The word "should" is used to indicate that among several possibilities one is recommended as particularly suitable without mentioning or excluding others. In the preparation of this standard, the following documents/publications were considered: PAES 228:2005 Agricultural Machinery - Fiber Decorticator - Specifications PAES 244:2010 Agricultural Machinery - Biomass Shredder - Specifications Becina, Ariel Dexter Janairo.
