Important Information 26 27 1. Read the methods carefully. If you have any questions, contact one of the co-Study Directors. 28 29 2. It is advised to make at least one practice run before the trial using your own materials so that you 30 can minimize errors in manipulations. Check that all pipettes, equipment, and 3M Petrifilm SALX 31 supplies are on hand. 32 33 3. Make the determination on the specified date. Store the test portions according to the instructions. 34 It is essential for the validity of the trial that all collaborators commence the analysis of each test portion 35 on the designated day. Immediately upon receiving each shipment, confirm the contents with the Study 36 Director by faxing the form provided in the shipment. 37 38 4. THIS IS A STUDY OF THE METHOD, NOT OF THE LABORATORY. THE METHOD MUST BE FOLLOWED AS 39 CLOSELY AS PRACTICABLE, AND ANY DEVIATIONS FROM THE METHOD AS DESCRIBED, NO MATTER HOW 40 TRIVIAL THEY MAY SEEM, MUST BE NOTED ON THE REPORT FORM. 41 42 5. Report all of your results as soon as analyses are completed. Do not do more or less than indicated in 43 the instructions. For example, do not do duplicate analysis and report the best or average result. More 44 or fewer results complicate the statistical analyses and may invalidate your results. Data sheets are 45 provided with these instructions and indicate which results are to be reported. Please include any 46 criticisms, suggested improvements, or general comments about the products on the Collaborators’ 47 Comments Form provided. Any results that were derived from modified protocols should be included 48
