8.1.2 Non tested laminates
Where the mechanical properties have not been verified by tests the respective properties shall be determined according to one of the following options:
8.1.3 Determination of glass content
Option 1:
The fibre mass content for each individual layer may be determined from Table 9 and using the law of mixture.
Option 2:
The glass content may be determined by direct measurement of the laminate without the gel coat and/or a burn-out test.
A minimum of five samples shall be used.
8.1.4 Calculation of mechanical properties
The mechanical properties for non tested laminates to be used in the scantling calculation shall be determined according to Table 10. This table refers to E-glass assuming a nearly isothropic lay-up (deviation < 20 %).
