The only evidance of compliance in this <br />regard is the appearance of the Classification Mark of Under- <br />writers Laboratories at-tache4 to the product showing the Fire <br />Hazard Classification applicable to the product. The Classifica- <br />tion Hark indicates that the product has been produced under the <br />Follow -Up Inspection Program of Underwriters Laboratories, Inc. <br />We are presently in the process of conducting various supplemental <br />tests to establish specifications for use in the Follow -Up <br />Inspection Program with respect to this material. When this work <br />has been completed, we will prepare e. FoHow-Up Inspection <br />Procedure, a formal Report, and will establish Classification of <br />the product in our regular publications. When that work has been <br />completed, you will be in a position to proceed with authorized <br />application of Classification Marks to the material. The end <br />use of the product in question is, of course, the decision of the <br />authorities having jurisdiction. <br />Should you have any questions on the above, feel free to contact <br />the writer at any time. <br />jry trul yo!•1ES J�URDANojectEngineerre Protection Department <br />JJU:ih <br />R .YASb <br />Associate Managing Engineer <br />Fire Protection Department <br />
