Ball, USP 2,643,611(1953) CA 47,9016 (1953)(Inhibitor strips for large-grain rocket propellants are attached by means of an adhesive consisting of NC dissolved in Et lactate, cello solve, mesiryl oxide, Bu acetate or diacetone alcohol. These solvents act as a mutual plasticiser for the material of the inhibitor strip and for the propellant itself) 5)G.Epstein, "Adhesive Bonding of Metals," Reinhold, NY(1954> 6)ASTM Committee D-l4on Adhesives, Standards on Adhesives, Specifications, Physical Tests, Definitions, Philadelphia, Penna(1954) 7)... [Pg.103]

However, evaluations cannot answer every question policy makers might ask in relation to a particular program. In particular, they cannot address many what if questions. What if the program were made national What if the proxy means-test formulas were changed Such questions can be examined, even if not definitively, using a variety of ex... [Pg.231]

Standards also give definitions for the characteristics of a material or product, or they provide the means and methods to implement quality tests for them. The difference lies in their method of preparation, therefore, in their legal status. A standard is the result of a consensus between all parties concerned. These parties represent the manufacturers of the product or material, the consumers who are the industries or user services or, ultimately, consumer associations, as well as, finally, governments. [Pg.294]

The basic condition of the Standard application - the availability of stable coupled probabilistic or the multiple probabilistic relations between then controlled quality indexes and magnetic characteristics of steel. All the probabilistic estimates, used in the Standard, are applied at confidence level not less than 0,95. General requirements to the means of control and procedure of its performance are also stipulated. Engineers of standard development endeavoured take into consideration the existed practice of technical control performance and test at the enterprises that is why the preparation of object control for the performance of nondestructive test can be done during the process of ordinary acceptance test. It is suggested that every enterprise is operated in correspondence with direct and non-destructive tests, obtained exactly at it, for detailed process chart and definite product type, however the tests have long since been performed after development of the Standard displayed that process gives way to unification. [Pg.25]

Assistance in problem definition and in developing a test program should be sought from persons experienced in the field. If your organization has a consultant in separations of this land, by all means m e use of the expertise available. If not, it may be wise to employ an outside consultant, whose special knowledge and guidance can save time, money, and headaches. It is important to do this early after the separation equipment has been installed, there is httle a consultant can do to remedy the sometimes disastrous effects of a poor selection. Often it is best to work with established equipment manufacturers throughout the selection process, unless the problem is unusually sensitive or confidential. Their experience with problems similar to yours may be most helpful and avoid many false starts. [Pg.1749]

Scammel proposed its separation by means of a definite crystalline compound with phosphoric acid. This body has the composition CioHjgO. H3PO4. The use of phosphoric acid is the basis of the British Pharmacopoeial test for cineol in essential oils. [Pg.277]

Since the foregoing tests were carried out at -identical conditions of compn and temp, and in a standard test fixture, the burning times serve as a means of checking the relative fineness of thea powdered tungsten fuels. The rapid burning times indicate that both M-10 and M-20 are very fine. Also, the M-10 is definitely finer than M-20, as shown by the difference in burning times... [Pg.523]

A waste is toxic under 40 CFR Part 261 if the extract from a sample of the waste exceeds specified limits for any one of eight elements and five pesticides (arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver, endrin, methoxychlor, toxaphene, 2,4-D and 2,4,5-TP Silvex using extraction procedure (EP) toxicity test methods. Note that this narrow definition of toxicity relates to whether a waste is defined as hazardous for regulatory purposes in the context of this chapter, toxicity has a broader meaning because most deep-well-injected wastes have properties that can be toxic to living organisms. [Pg.784]

Commercial Testing. The commercial test lab is by definition, in the business of testing. The satisfaction of its customers is paramount. Quality service and responsiveness holds old customers and attracts new ones. Getting dependable data fast is important, but here cost is critical. In a competitive market, the ability of LIMS to bring down the effective cost per test means more profit and/or the ability to keep or increase one s market share by lowering prices. [Pg.10]

We can rephrase the previous lemna to provide in effect a syntactic definition of what it means for a path to be an execution sequence. If we are given any path s fran START through a scheme P, we can build the sets Q(s,T,0) and Q(s,T,l) for each test T as before. We construct the various values val (u,j) as before following s and place t in Q(s,T,j) when demanded by the algorithm, step (3), but do not worry as to whether this is a consistent definition. As before, this is an actual construction only for s finite. [Pg.53]
