Standard Practice for Evaluation of First Aid Antiseptic Drug Products

SIGNIFICANCE AND USE
5.1 The procedures in this practice should be used for in vivo evaluation of the antimicrobial activity of drug products applied topically to the skin that are intended to help prevent infection in minor cuts, scrapes and burns.  
5.1.1 This practice is applicable for testing liquids, ointments, powders, films, or dressings, containing or impregnated with an antimicrobial agent, for their effect to reduce an enhanced skin microflora or their effects to suppress the growth of the skin flora, or both.
SCOPE
1.1 The tests described in this practice are designed to evaluate antimicrobial agents in formulations intended for use as first aid antiseptic products for their ability to reduce or suppress the growth, or both, of the skin microflora.  
1.2 A knowledge of microbiological techniques is required for these procedures.  
1.3 Performance of this procedure requires the knowledge of regulations pertaining to the protection of human subjects. (See CFR Parts 50 and 56.)  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

4. Summary of Test Method
4.1 These test methods describe standard in vivo techniques to determine the following:
4.1.1 Effect of the Test Formulation to Reduce an Artificially Enhanced Skin Microbial Flora—The forearms of subjects are
occluded for 48 h prior to application of the test formulation to increase the microbial population on the skin of the volar forearm
surface. At treatment the occlusion material is removed and the skin is allowed to dry, the test formulation is then applied to
selected sites. At a pre-determined time(s) following application, the sites are microbiologically sampled and the samples plated
for total aerobic bacteria count. The counts obtained from the treated sites are compared to counts obtained from untreated
occluded sites.
4.1.2 Effect of the Test Formulation to Suppress the Growth of Normal Skin Flora When Applied As a Dressing—The dressings
are applied to the forearm for 24 h. The density of the resident microorganisms that develop under the dressings are compared
