26、 3). When partial-length creep specimens are used, only eight joints shall be considered (Joints 1, 2, 5, 6, 9, 10, 13, and 14 in Figure 6). Creep (DJntn) of a bonded cross-section shall be the average of the four creep measurements D1, D2, D3, and D4(see Figure 5).The calculations for each creep sp

27、ecimen shall be as follows:11NDJnt nnN=(a) Overall creep:0.05 mm (for Environments A and B1) 0.6 mm (for Environment B2)DDD DDJnt n+123 44whereN = 14 when considering a full-length specimen= 8 when considering a partial-length specimen= 6 when one of the partial-length specimens is discarded(b) Cree
