When the natures of each explosive are similar to one another, an inducted explosion is more likely to occur if the diameter is larger, the explosive more tightly enclosed, and the ignition involves more energy. The BAM 50/60 steel pipe test can be used to investigate the explosion inducing feature which meets the above conditions. A 50/60 steel pipe can enclose the sample more tightly than a VP pipe. 

The propellant (400 to 460g) of was put into the 50/60 steel pipe, the void was filled with sand, and the pipe was attached to 50g of a No. 21 booster to detonate. Fig. 5.51 shows the results of plotting the bubble energy (E n )in the steel pipe test against that of the VP pipe test (E b ). Among the composite propellants, only sample C induced... 

Also differing from the case of the VP pipe, in the steel pipe test, the bubble energy of a part of the propellant which did not have an induced explosion was roughly constant for each sample (0.180 to 0.238 MJ), with no difference based on the amount of HMX observed. One explanation for this is that the increase of the explosion energy by an uninduced explosion was absorbed into the sand. This should be established by future experiments. 

PVC pipes, while the steel pipe test, the range was constant and nearly 0. Although these differences have not yet been experimentaly investigated, some hypotheses may be suggested.

RDT or 30MS sampling are appropriate for identifying areas that require priority action to reduce lead levels. Previous studies show that the lead pipe test (pipe rigs at the treatment facility) can also be suitable for this purpose. 

Assessing/predicting the effect of measures A distinction should be made between measures taken at the treatment facility and measures taken at specific properties. To evaluate the effect of measures taken at the treatment facility (pH increase, orthophosphate dosing, etc.), both the RDT sampling procedure and the lead pipe test are appropriate. For predietion purposes the lead pipe test is most eonvenient. 

Several accelerated long-term tests for assessing the stress-cracking resistance (ESC) to be less time consuming than conventional creep tests were developed such as the full notch creep test (FNCT) as one of the most important methods using notched specimens (an overview about accelerated methods is given in Chapter 4.7, Stress Cracking Resistance )- Moreover a couple of methods for components or semi-finished products (such as plastic pipes) are available where the full-scale pipe test and small-scale steady state test (S4 Test) are the most used ones. 

The total direct material and manpower costs for construction of the plant are 605,400 and 152,100, as shown in line 11. These sum to 757,500 and include items that cannot be charged to the individual equipment items (e.g., charges for instrument testing, pipe testing, and equipment grounding). Note that the installed costs of the equipment items are displayed on the List View ...
