Six Testing

The test gas may be propane, hexane, or gasoline vapors. Eor end-of-line deflagration flame arresters, tests shall be performed twice each for three ignition sources, for a total of six tests. Eor in-line detonation flame arresters three detonation tests are required. 

Comparison of Effectiveness Tests. Three laboratory methods were compared the revised standard dispersant effectiveness test used and required for regulation in the United States, the swirling flask test (developed by Environment Canada), and the IFP-dilution test (used in France and other European countries) [1693]. Six test oils and three dispersants were evaluated. It was concluded that the three tests gave similar precision results, but that the swirling flask test was fastest, cheapest, simplest, and required the least operator skill. 

Observing and Inferring Identify which element was more active and which element was less active in each of the six tests conducted. Summarize the information in Data Table 3 by writing the symbol of the element in the appropriate space. 

Affix labels to six test tubes. Place your name on each label and number the test tubes 1 through 6. Place the test tubes in a rack. 

The permeability (kg/m h mbar) for water vapor through the dried product fluctuates by a larger margin, which can be estimated from all six test runs (Table 1.9 and 1.10.1) as 1.1 10-2 25 %. However, the measurement of this data is of interest to judge whether the b/p will influence the process time, as can be the case with products which have a high solid content and are dried with a large thickness. Small b/p can also result from a skin on the surface of the product (see [1.132]).

In 1972, skin applications of 0.01Z and 0.1Z CS were used to determine the effects of skin pigment on susceptibility to sensitization, sensitizing and Irritating concentrations of CS, and cross-sensltlzatlon with CN. Eighty-six tests were summarized, and results are available on 45 cases. Seven of 15 subjects were sensitized In skln-plgment experiments subjects with lighter skin seemed more susceptible to sensitization. Twenty previously CS-sensltlve subjects showed no cross-reactivity to CN, although 18 developed primary Irritation dermatitis when exposed to 0.2Z CN. Four of 20 subjects developed primary Irritation dermatitis when exposed to 0.1Z CS, but not to 0.01X CS. 

In the six-plate test, the sample is brought in a punch hole or a paper disc on each of the six test plates that have been inoculated with Bacillus cereus. Bacillus subtilis (pH 6), Bacillus subtilis (pH 8), Sarcina lutea, Escherichia coli, and Bacillus stearothermophilus, respectively (33). Once the samples have been introduced, the plates are incubated for the required time at the required temperature. If, on one of the plates, a zone of inhibition of 1.0 mm is observed around the disks or holes, the result of the test is considered positive, provided that interferences have been excluded. 

In reporting tests results the sample is noted as no reaction , decomposition (w/o expln) and "explosion . The drop weight in kg and the lowest height in cm (calculated as Impact energy. in kgm) are given as a measure of the sensitivity to impact, if in six tests at least one expln occurs. The sensitivity to impact of a substance is greater the smaller the impact... 

To prepare a standard curve, add 0.25 mL of HABA reagent to 10 mL of avidin solution. Incubate 10 min at room temperature and record the absorbance at 500 nm of 1 mL avidin-HABA complex with 0.1 mL buffer, pH 6.0 Distribute 1 mL of the avidin-HABA complex into six test tubes. Add to each the biotin solution in a range of 0 005-0.10 mL. Bring the final volume to 1.10 mL with pH 6.0 buffer, and record the absorbance at 500 nm of each concentration point. Plot a standard curve with the nanomoles of biotin vs the decrease in absorbance at 500 nm. An example of a standard curve is illustrated in Fig 3... 

The IUPAC Commission on Oils, Fats and Derivatives undertook the development of a method and collaborative study for the determination of triglycerides in vegetable oils by liquid chromatography. Three collaborative studies were conducted from 1985 to 1987. Refinements were made in the method after the first collaborative study, and the second and third collaborative studies demonstrated that the method produces acceptable results. Materials studied were soybean oil, almond oil, sunflower oil, olive oil, rapeseed oil, and blends of palm and sunflower oils and almond and sunflower oils. Six test samples were analyzed by 18 laboratories from 11 countries in the second study 4 test samples were analyzed by 16 laboratories from 12 countries in the third study. The method for the determination of triglycerides (by partition numbers) in vegetable oils by liquid chromatography was the first action adopted by AOAC INTERNATIONAL as an IUPAC-AOC-AOAC method (103).

It does not bum after six tests. It is immediately self-extinguishing. 

Water solubility of hydrocarbons. Label six test tubes with the name of the substance to be tested. Place into each test tube 5 drops of the appropriate hydrocarbon hexane, cyclohexene, toluene, unknown A, unknown B, unknown C. Add about 5 drops of water dropwise into each test tube. Is there any separation of components Which component is on the bottom which component is on the top Mix the contents as described above.

An ATB was performed on only one of the two LICs when TOCDF began VX destruction operations. The ATB results from LIC2 were used as data in lieu of performing a VX ATB on LIC1. The VX ATBs for LIC2 were performed under two trial bum conditions, high and low temperature, requiring a total of six test runs (three test runs under each condition). 

Table 19. Impact sensitivities given as the product of fall weight and fall height (kp m). In the following Table the kp m values are listed at which at least one of six tested samples explodes.

Six tests are performed on each substance in order to classify them into one of these categories. The results of these tests can range from no reaction to complete detonation . Those tests are briefly summarized in Table 6.5.
