believed that the grading work in progress on cleanliness would help 

 to eliminate the need for the weight standards. The present perimeter 

 measurements were preferred over the three-axis method described by 

 Dr. Bennett. It was agreed that the present practice of marketing 

 sponges by size is to be recommended. It was agreed that the present 

 practice of checking size by only one "go-no-go" ring is inadequate 

 and that perimeters should be used instead. 



10. In more detail, it was recommended that the following changes 

 be made in the Federal Specifications C-S-631b. Parts not mentioned are 

 acceptable as they stand. A section should be added to clarify grading 

 by tests similar to those being developed by Dr. Bennett. Types may 

 then eventually reach a status of secondary importance. 



It is recommended that Federal Specifications C-S-631b should be 

 changed to read:
