Sec. 226.58  Laboratory controls.

    Laboratory controls shall include the establishment of adequate 
specifications and test procedures to assure that the drug components 
and the Type A medicated article(s) conform to appropriate standards of 
identity, strength, quality, and purity. Laboratory controls shall 
include:
    (a) The establishment of master records containing appropriate 
specifications and a description of the test procedures used to check 
them for each kind of drug component used in the manufacture of Type A 
medicated article(s). This may consist of the manufacturer's or 
supplier's statement of specifications and methods of analyses.
    (b) The establishment of specifications for Type A medicated 
article(s) and a description of necessary laboratory test procedures to 
check such specifications.
    (c) Assays which shall be made of representative samples of finished 
Type A medicated article(s) in accordance with the following schedule:
    (1) Each batch of a Type A medicated article(s) manufactured from an 
undiluted drug shall be assayed for its drug component(s).
    (2) In the case of Type A medicated article(s) which are 
manufactured by dilution of Type A medicated article(s) assayed in 
accordance with paragraph (c)(1) of this section, each batch shall be 
assayed for its drug component(s) with the first five consecutive 
batches assaying within the limitations, followed thereafter by assay of 
representative samples of not less than 5 percent of all batches 
produced. When any batch does not assay within limitations, each batch 
should again be assayed until five consecutive batches are within 
limitations.
    (d) A determination establishing that the drug components remain 
uniformly dispersed and stable in the Type A medicated article(s) under 
ordinary conditions of shipment, storage, and use. This may consist of a 
determination on a Type A medicated article(s) of substantially the same 
formula and characteristics. Suitable expiration dates shall appear on 
the labels of the Type A medicated article(s) to assure that the 
articles meet the appropriate standards of identity, strength, quality, 
and purity at the time of use.
    (e) Adequate provision to check the reliability, accuracy, and 
precision of any laboratory test procedure used. The official methods in 
``Methods of Analysis of the Association of Official Analytical 
Chemists,'' \1\ methods described in an official compendium, and any 
method submitted as a part of a food additive petition or new-drug 
application that has been accepted by the Food and Drug Administration 
shall be regarded as meeting this provision.
