The apparatus shall be assembled as follows (see figures 4: The circular base plate shall be placed in the spillage pan. This pl
42、ate contains a circular area of the same outside diameter as the bottom of the 500 ml cylinder. The 500 ml cylinder shall be seated in the circular area. The small holed loading screen shall be placed on top of tube number 3, and this unit set on top of the 500 ml cylinder. The brass distribution pl
43、ate shall be placed on tube section number 2 and then tube number 1 shall be added. After the numbered tubes and plates are mounted correctly, the funnel shaped hopper shall be placed into tube number 1; The spillage pan shall be grounded to a cold water pipe with a grounding cable, the spirit level
44、 placed on the base plate, and the leveling screws adjusted until the.plate is level solid. 4.5.6.3 Conditioning The sample of casting powder shall be conditioned to a constant temperature of 80O. The casting powder does not have to be conditioned for humidity provided the moisture content of the sa
45、mple is between 0.1 and 3.0 percent and the test is made in a room having a relative humidity between 30 and 80 percent. 4.5.6.4 Procedure. The empty 500 ml cylinder shall be tared, the weight recorded, an? the apparatus assembled as specified in 4.5.6.2. The spouted c qltainer shall be tared and ap
46、proximately 545 gm of powder weighed out. the hopper in one motion. the column, all parts of the apparatus above the 500 ml cylinder shall be removed. This shall be accomplished by holding the bottom cylinder firmly and lifting off the other sections as units. Excess powder shall be struck off by us
47、ing the brass bar with a 1/4 inch edge held flush with the top of the cylinder and with a flow constant movement across the cylinder top toward the operator. The bar shall not be slanted nor excess powder struck off again. The cylinder shall be removed from the base plate and any powder that may be
48、clinging to the sides of the container, brushed off. The powder and cylinder shall be weighed and the weight recorded. The screen loading density shall be calculated to determine compliance with 3.7 by sybtracting the tared weight of the cylinder from the gross v-eight of the powder and cylinder and
49、 multiplying the difference by 0.002. The powdershall be dumped into When all the powder has run through 4.5.7 Grain dimensions, Major Defect. The grain dimensions shall be determined in accordance with Method 504.4 of Standard MIL-STD-286. 5.
