4.2.1.5 All the instruments associated with Project 6.he will be operated at once for a minimum of eight hours during a sea trial. Afterwards each instrument will be examined, and its mechanical performance during the test will be assessed. Under these conditions, mechanical weaknesses should be disclosed and corrected. 4.2.1.6 Any experimental work left uncompleted at the time of departure of the ships for the site must be completed by Project 6.4e personnel aboard the ships prior to arrival at the test site. 2.1.7 2.2 Additional details will be available in Tab E-9. Operational 4.2.2.1 Shipyard workers from San Francisco Naval Ship- yard will be required to install instruments aboard the ships. Once installed, air samplers will receive final adjustments from Project 6.he personnel. Except for a few cases, none of the instruments need be moved from their initial installation points. The exceptions include several air samplcrs in the boiler air system and several clock-wound recording instruments. h.2.2.2 Practice recovery operations will be attempted on all instruments and duct sections, Their recoveries will be timed in order that close estimates may be made of: a. operations after each shot. How many teams are needed for recovery b. How many samplcs each time should recover and how many discrite operations must be performed by each team. complete its recovery. 4.2.3 c. How much time each team will rcquire to For results and details, sce Tab E-10.
