Important Notices



Analytical methods and procedures in this compendium have undergone rigorous scientific and systematic scrutiny to determine the performance characteristics for the intended analytical application and fitness for purpose. AOAC INTERNATIONAL members and other volunteers have reviewed the analytical results and determined that a particular method is appropriate for the analyte and matrix stated, provided the analysis is conducted by a competent analyst as written. No warranty, implied or expressed, is made by AOAC INTERNATIONAL on the methods described, their safety, or products mentioned. AOAC INTERNATIONAL, its members, and nonmember volunteers who have aided in the development and validation of methods included in this volume assume no responsibility for any economic, personal injury, or other damage that may occur to individuals or organizations because of the use of these methods.

Commercial Products

Names of manufacturers, suppliers, and trade names are furnished solely as a matter of identification and convenience and reflect the conditions within which each method was developed in the originator laboratory. Inclusion of this information does not imply AOAC promotion, approval, endorsement, or certification. The same or equivalent products, instruments, supplies, apparatus, or reagents available from manufacturers and suppliers other than those named, or other brands from other sources, may serve equally well if proper validation indicates their use is satisfactory.


Do not perform analyses using AOAC® Official MethodsSM unless you are knowledgeable about their potential dangers or hazards and have received appropriate training. Do not handle instruments, supplies, apparatus, reagents, biohazards, or other products when unfamiliar with their operation or the potential hazards associated with their use. If a method requires the use of potentially hazardous equipment or products, see manufacturer’s safety and cautionary instructions. Material Safety Data Sheets (MSDS), or the equivalent, must be read and understood prior to the use of materials specified by a method.

Always use fume hoods, proper ventilation, and protective clothing and equipment when required.

See Appendix B, "Laboratory Safety," for further information on safety.


Each AOAC® Official MethodSM has its own method number that is part of the title. The number located in the upper left is only a locator number and not the method number. For example:

AOAC Official Method 2008.01
Lasalocid Sodium in Animal Feeds and Premixes

2008.01 is the method number and 5.2.07 is the number used to facilitate locating methods. Method numbers indicate the year the method was adopted (in this case 2008) followed by the order in which the method was approved that year (in this example, it is the first method approved in 2008). The first set of numbers in the locator number indicates the chapter (in this case, Chapter 5), the second set indicates the subchapter (in this case, subchapter 2), and the last set indicates the order in which the method appears in the subchapter (in this case, it is the seventh method).

When referencing AOAC® Official MethodsSM, only the method number should be used as seen in the following example:

Each AOAC standard has its own sequential codification that is located in the standard itself. The codification number is located in the upper left in the heading of the standard. For example:

AOAC SMPR 2011.003

Standard Method Performance Requirements for Vitamin A in Infant Formula and Adult/Pediatric Nutritional Formula

Intended Use: Global Dispute Resolution Method

2011.003 is the codification number of the standard. In this example, 2011 represents the year in which stakeholders reached consensus on the standard. The second part of the codification number (in this example, 003) represents the order in which the standard was approved. For example, 2011.003 is the third voluntary consensus standard adopted by an AOAC stakeholder panel in 2011.

When referencing AOAC SMPRs in the Official Methods of Analysis of AOAC INTERNATIONAL, only the standard numbers should be used as seen in the following example:

AOAC INTERNATIONAL adopts methods that show by their performance data what can be expected of them. As analysts use AOAC® Official MethodsSM, they generate additional information and data concerning applicability, specificity, sensitivity, reliability, and accuracy of the methods. Analysts are requested to advise AOAC INTERNATIONAL about their experiences with the AOAC® Official MethodsSM published in this book. In particular, analysts should notify AOAC INTERNATIONAL of problems in the performance of an Official MethodSM, which may indicate the method should be revised or restudied.

AOAC INTERNATIONAL is a standards developing organization and therefore adopts voluntary consensus SMPRs that are then used to adopt methods that meet the standards. Direct comments to AOAC INTERNATIONAL at standards@aoac.org.
