1.1 These test methods cover the determination of the resistance of liquid adhesive preparations to microbial attack in the container by challenging adhesive specimens with cultures of bacteria, yeast, or fungi, and checking for their ability to return to sterility. These test methods return qualitative results.1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These test methods are designed to be used by persons trained in correct microbiological technique. Specific precautionary statements are given in Section 8.

Standard Test Methods for Resistance of Adhesive Preparations in Container to Attack by Bacteria, Yeast, and Fungi
5.1x00a0;These test methods are used to demonstrate whether an adhesive preparation is sufficiently protected with biocide to resist attack by bacteria, yeast, and fungi during its storage life. They are patterned after methods used by biological laboratories serving the adhesive industry. 5.2x00a0;These test methods may also be used to determine the efficacy of different biocide systems against specific microorganisms. 5.3x00a0;These test methods are especially useful when tested against wild-type microorganisms which have been isolated from contaminated adhesives as an aid in determining the amount and type of biocide necessary to kill or inhibit the growth of the contaminants. If an isolated microorganism not generally used as a challenge organism, is chosen as the inoculum, it is important to identify the organism and determine on which medium and under what conditions it will grow, in order to demonstrate the efficacy of the biocide. 5.4x00a0;The results obtained when using the procedures given in these methods apply only to the species which are used for the testing. The test species listed in Section 9 are frequently used by laboratories to test for antimicrobial properties, but they are not the only ones which could be used. Selection of the species to use for these test methods requires informed judgment by the testing laboratory or by the party requesting the tests. It is also important that species which commonly attack adhesives be used. See 9.4. 5.5x00a0;The presence of an active biocide carried over from the adhesive specimen to the agar could have an inhibiting effect on the growth of microorganisms, resulting in no growth during the span of a normal incubation period, when in fact, viable microorganisms are present, but their growth has been slowed down or held in stasis. The use of Letheen agar and broth is recommended to neutralize the effect of this carry-over.Note 4x2014;Letheen agar may be used for the streak plates, or if another agar is chosen for testing, a Letheen agar plate could be streaked as a control to test against the neutralizing effect. Even more effective would be diluting the challenged adhesive specimen with Letheen broth and running Letheen agar pour plates. See Note 1 and Note 3. Extending the incubation period of negative plates would be another safeguard. To neutralize thiazoline-based preservatives, 10 to 50 ppm of sodium thioglycolate can be added to the medium. 5.6x00a0;These test methods are dependent upon the physiological action of living microorganisms under a reported set of conditions. Conclusions about the resistance of the test adhesive to microbiological attack can be drawn by comparing the results to simultaneously run controls of known resistance. See X5.2 for statements regarding test repeatability. 1.1x00a0;These test methods cover the determination of the resistance of liquid adhesive preparations to microbial attack in the container by challenging adhesive specimens with cultures of bacteria, yeast, or fungi, and checking for their ability to return to sterility. These test methods return qualitative results. 1.2x00a0;The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

Methods of Test for Food Microbiology-Test of Mold and Yeast Count
This International Standard specifies a method for the enumeration of bacteria, yeasts and moulds in cereals, pulses and their immediate derived pro-ducts (flour, semolina, bran, etc.). It takes into account the standards giving general guidance, notably ISO 7954, prepared by sub-committee 9, Microbiology, of ISO/TC 34, Agricul-tural food products. Reference should be made to ISO 7218 for the good laboratory practice for microbiological exam-inations. NOTE 1 Owing to the nature of yeasts and moulds, the enumeration is subject to certain imprecisions.

Microbiology. General guidance for enumeration of yeasts and moulds. Colony count technique at 25 degrees C.
The method consists in preparing of poured plates using a specified selective culture medium and a specified quantity of a test sample, further dilutions of the test sample. Then aerobic incubation of the plates at 25 degrees centigrade for 3, 4 or 5 days, followed by calculation of the number of yeasts and moulds per gram or per millilitre of the sample from the number of colonies obtained on plates chosen at dilution levels so as to give a significant result.
