默认 pci plant certification 9b40 for bridge beams

pci plant certification (b4) for bridge beams
i would appreciate it if someone could provide the minimum requirements for a sample precast/ prestressed bridge beam which will be tested for a plant pci's b4 certification. we are looking for a minimum beam length, minimum number of straight/ deflected strands and other reinforcement, etc...

check with the pci directly or refer to their certification manual.
