Mass testing

The vent sizing package (VSP) was developed by Fauskes Associates, Inc. The VSP and its latest version VSP2 employ the low thermal mass test cell stainless steel 304 and Hastelloy test cell with a volume of 120 ml contained in a 4-1, high-pressure vessel as shown in Figure 12-13. The typical ([t-factor is 1.05-1.08 for a test cell wall thickness of 0.127-0.178 mm. Measurements consist of sample temperature Tj and pressure Pj, and external guard temperature Tj and... 

The device consists of a low thermal mass test cell of 110 ml volume. This is made of stainless steel with a 0.015-mm wall thickness, but test cells made from other materials can be used. The contents of the cell are mixed using either a magnetically driven stirring bar or a direct drive agitation test cell. The test cell is... 

The constant-jaw displacement rate test mode is most frequently used. It meets most of the requirements for mass testing such as in the quality control situation, but various test analysis methods have made it quite suitable for design as well as research purposes. Displacement rates from 0.2 to 20 inches/min. are normally used, but some testing equipment provides reasonably controlled rates upwards of 10,000 in./min. Extremely low rate tests are time consuming, of course, but some specialized equipment has been designed to produce strain rates down to 8 X 10 7 inches/min. (1, 4). 

Variable sample mass test with the MKIII ballistic mortar 5 5 G ... 

The sample vessel in the variable sample mass test is made of a thin polyethylene tube with a diameter of 23 mm. The bottom is closed by adhesive tape. The initiating explosive with a No.6 electric detonator and 0.6 g of PETN is inserted into the inner tube used in the variable initiator test. A sample vessel assembly is shown in Fig.3.138. 

Variable sample mass test using the ballistic pendulum. 

Any substance or mixture which, in the 4 1 or 1 1 sample-to-cellulose ratio (by mass) tested, exhibits a mean burning time less than the mean burning time of a 3 2 mixture, by mass, of potassium bromate and cellulose. 

The blends (PET plus core-shell elastomers) were compounded using a co-rotating twin screw extruder. The contains of particules ranged from 7 to 21 % in mass. Test bars were injection moulded in a second step. In order to produce compound of different levels of crystallisation, the mould wall temperature was varied. Truly amorphous mouldings could not be obtained. However, for mould temperature of 5°C only a small amount (less than 8 %) of crystalline phase was observed. These mouldings will be considered as amorphous, since their continuous phase is amorphous. Conversely, a wall temperature of 145°C made it possible to reach the maximum level of crystallisation (approximately 30 % in mass). Finally, no evidence for a significant crosslinking effect due to reactive nodules was found. 

Uniformity of dosage units. Generally, acceptance criteria should be set for weight variation, fill volume, and/or uniformity of fill. For powders intended for reconstitution, uniformity of mass testing is generally considered acceptable. 

The graph shows that there is no proportional response of the ECD detector over the entire range of masses tested. (Y axis peak height/mass Cli injected X axis mass of CB injected). 

Fig. 6.44 Kinetics of hydrogen generation by NaBH4 hydrolysis. Test equipment hydrogen generator designed at 0.8 L H2 min. Fuel composition NaBH4/Na0H/H20 = 158.5/76.5 (mass). Test conditions 0.10 MPa, 295 K.

Water absorption. Before impregnation specimens were dried to constant mass. Tests showed that water absorption of impregnated specimens was zero, and check samples were characterized by 4.5-4.7% water absorption. 

The uniformity of mass test does not have to be performed when the test on tmiformity of content according to 2.9.6 has been performed for all the active substances included in a preparation. The test on tmiformity of content gives much more information about the variation in the... 

Indispensable mass test facility for HTGR fuel development. 

While the reduced enzymatic susceptibility of the aromatic ester bonds is caused by the interaction of the long chains in the polymer, the chain length itself has no direct influence on the biodegradability above a minimum molar mass. Tests with copolyesters from terephthalic acid, adipic acid and 1,4-butanediol, which were chain extended with hexamethylene-diisocyanate, did not result in a decrease in the biological degradation rate (in a compost simulation test), although the molar mass of the prepolyesters of about 48,000 D was increased to 232,000 D by the chain extension [85]. 

Visual inspection For the purpose of assessment of the rock mass. Such a test indicates the in situ state of the rock mass. Tests may be conducted in situ or under lab conditions in accordance with British Standard Institute Standard BS 5930 (1999).
