11、ladder shall be similar to that shown in Fig.1.The bladder shall be comprised of a reinforced elastomerictube that is capable of providing a watertight capsule aroundthe subject joint specimen.4.2.2 The bladder shall be able to safely contain an internalwater pressure of at least 11.0 psi(75 kPa).4.
12、2.3 The bladder shall have plumbing connections thatallow the bladder to be pressurized with water and that allowtrapped air to be bled out of the bladder.4.2.4 The bladder shall have a pressure gage that indicatespressure in the bladder.This gage shall be capable of measur-ing 11 psi(75 kPa)(gage)w
