This Standard specifies the sampling and sample treatment methods of eggs and egg products. This Standard applies to the sampling and sample treatment of eggs and egg products.2 Equipment and Materials
2.1 Sampling tools The sampling tools shall be made of stainless steel or other materials of appropriate strength, with smooth surfaces, no gaps, and rounded corners.
