Cal. Code Regs. tit. 17 § 12590

Current through Register 2024 Notice Reg. No. 25, June 21, 2024

Section 12590 - Tolerance per Batch

(a) Wherein 10 percent or more of a particular batch is found to be in buckled condition, the entire batch (both buckled and normal appearing cans) shall be restrained.

NOTE: By "buckled condition" is meant those cans with strained ends caused by excessive internal pressure during processing or cooling, resulting in one or both ends having elevated or wavy areas such that they have become unsatisfactory for retail trade.

(b) Batches wherein less than 10 percent of the number of cans are buckled, only that material showing buckled condition shall be restrained and the normal appearing cans may be released.

(c) Buckled cans shall be reformed as soon as possible after the cans have been restrained. The reforming of the cans must be done before any arrangements can be made to submit the material to a flip vacuum test.

NOTE: The reforming consists of forcing the distorted top or bottom back to its normal position. Ends slightly distorted may be reformed by thumb pressure whereas ends more severely distorted or strained may be reformed with the closing machine chuck or other suitable tool. Reforming the ends might have some effect upon the vacuum of the cans and as a consequence flip testing should not follow the reforming operation until approximately 30 days have elapsed.

(d) If swells develop during the holding period, they are not to be destroyed, but submitted to the laboratory for examination.
