DATA PRESENTED 



Over a period of several years in a test program sponsored by the Owens-Corning Fiber- 

 glas Corporation and directed by Gibbs & Cox, Inc. and with the cooperation of many agencies, 

 a correlated body of data has been accumulated and analyzed to provide the basis for the data 

 presented in this manual. 



It would be a task beyond the scope of the manual to present all of the available data per- 

 taining to the state of the art at the time it is compiled. In this manual the data are applied 

 by example to marine design. Furthermore, since the data were obtained on a standardized 

 basis it is possible for any fabricator to make samples following the same construction and 

 process techniques as those used in the test program. If these fabricator samples are then 

 tested in accordance with the standard procedure, a calibration factor can be established re- 

 lating the fabricator's sample data to the whole body of data. If the fabricator continues to 

 follow the same pattern of calibration testing when working with new formulations of resin and
