"(&) Judgment of defects, lesions, or diseases referred to in paragraph (a) 
will be made by taking into account their intensity and seriousness and their 
effect upon the general appearance of the' tubers in accordance with the follow- 
ing criteria: 
"(1) Good shape: When the appearance of each tuber, or the general ap- 
pearance, is not marred by excessively pointed or constricted tubers or those 
with secondary growths or excrescences ; 
"(2) Cleanliness: When the general appearance of the tubers is not obviously 
affected by soil or dirt of any kind ; 
"(3) Tubers that are bruised, cut, cracked, punctured, etc., to such an extent 
that the lesions manifestly injure each tuber ; 
"(4) Hollow heart, black heart, or any abnormal discoloration of the tuber; 
"(5) Tubers that are old and clearly found to be soft and spongy; 
"(6) Sprouted tubers; when more than 10 percent have sprouts exceeding 
1.5 cm in length ; 
"(7) Tubers attacked by common scab (Actinomyces scaMes (Thax.) Guss.), 
black scab {Rliizoctonia solani Kuhn), etc., to such an extent that the lesions 
seriously affect the tuber ; 
"(8) Any decomposition of tubers, total or partial, due to any cause what-

TOLERANCES 
"(c) Within the criteria set forth in the preceding paragraphs, a tolerance Is 
allowed of 5 percent in seed potatoes and 10 percent in potatoes for consump- 
tion in the aggregate of defects, lesions, and common diseases. Among those 
percentages, only 1 percent of tubers affected by rot may be included, no toler- 
ance being allowed for diseases and pests that do not occur in Argentina. 
"(c?) The percentages of tolerance are calculated in the following manner: A 
determined number of packages is inspected in each shipment, and the per- 
centage of tubers attacked is ascertained in each of them by weight; those 
percentages having been obtained, the average is calculated and applied' to the 
whole shipment as the basis of tolerance. 
"(e) Shipments that exceed the tolerances established in paragraph (c) will 
be subject to selection (culling) or to disinfection, as the respective sanitary 
authorities may decide, charging the expenses thus arising to the account of 
the interested person. Shipments found to be attacked by dangerous diseases 
or pests that do not occur in Argentina will be reladen or destroyed, in accord- 
ance with the provisions of article 5, the cost thereof being charged to the 
account of the interested person.
