Results of tests of the occurrence of residual austenite in bearing steel... 

Bearing elements made of bearing steel were subject to studies. External ring-type elements with an internal race of 20 mm diameter and 12 mm height (Fig.4) were subject to tests using the contact probe and internal volumetric ones. Results of tests are given in Table 2. 

Table 7 gives the results of tests made with coloured products on real defects. 

The use of the surface ultrasonic waves seems to be convenient for these purposes. However, this method has not found wide practical application. Peculiarities of excitation, propagation and registration of surface waves created before these time great difficulties for their application in automatic systems of duality testing. It is connected with the fact that the surface waves are weakened by soil on the surface itself In addition, the methods of testing by the surface waves do not yield to automation due to the difficulties of creation of the acoustic contact. In particular, a flow of contact liquid out of the zone of an acoustic line, presence of immersion liquid, availability of chink interval leads to the adsorption and reflection of waves on tlie front meniscus of a contact layer. The liquid for the acoustic contact must be located only in the places of contact, otherwise the influence on the amplitude will be uncontrolled. This phenomenon distorts the results of testing procedure. 

The main purposes of the System of accreditation is to ensure reproducibility of measurements, harmonisation of rules and procedures of the National system of accreditation with guidelines of international organizations and national systems of different countries, creation of conditions for mutual recognition of the results of testing, calibration, attestation. 

CTB 941.2-93 defines laboratories subject to accreditation in National system. Among others laboratories with legal status, results of testing and measurements of which are used in assessment of safety of products, works and services, in diagnostics of technical state of critical safety objects and vehicles are noted. These laboratories use different NDT methods in their activities. 

For many projects, a basis set cannot be chosen based purely on the general rules of thumb listed above. There are a number of places to obtain a much more quantitative comparison of basis sets. The paper in which a basis set is published often contains the results of test calculations that give an indication of the accuracy of results. Several books, listed in the references below, contain extensive tabulations of results for various methods and basis sets. Every year, a bibliography of all computational chemistry papers published in the previous... 

Results of test work with this filter, producing cakes of 1 mm thickness using a 3 mm clearance, have been pubUshed (33,34). The cake formed on the medium was generally stable, giving high filtration rates over long periods of time, and the precoat type cake did not blind with time. There was no evidence of any size selectivity of the process the only exception was conventional filter aids which were preferentially picked up by the rotating fluid. This... 

Statistical Methods for Nonelectronic Reliability, Reliability Specifications, Special Application Methods for Reliability Prediction Part Failure Characteristics, and Reliability Demonstration Tests. Data is located in section 5.0 on Part Failure Characteristics. This section describes the results of the statistical analyses of failure data from more than 250 distinct nonelectronic parts collected from recent commercial and military projects. This data was collected in-house (from operations and maintenance reports) and from industry wide sources. Tables, alphabetized by part class/ part type, are presented for easy reference to part failure rates assuminng that the part lives are exponentially distributed (as in previous editions of this notebook, the majority of data available included total operating time, and total number of failures only). For parts for which the actual life times for each part under test were included in the database, further tables are presented which describe the results of testing the fit of the exponential and Weibull distributions. 

Is die material classified as liighly toxic or toxic based upon die results of tests on laboratory animals e.g, LD50 or LC50 data. NOTE as described in Chapter 11, LD50 and LC50 arc referred to as the dose of a chemical that is lethal to 50 percent of laboratory test animals. 

Since these groups in the SI system are non-dimensional, they can be used to present the results of tests of pumps in a family of pumps that are geometrically and dynamically similar. This may be done as shown in... 

In agreement with these considerations, the results of tests at Derby have shown that specimens exposed at 45° corroded 10-20% more than vertical specimens, and that 54% of the total loss was on the underside. In American tests on specimens exposed at 30° to the horizontal, 62% of the loss was on the underside. 

The general effect of low-alloy additions on the rusting of structural steel in the open air is illustrated in Fig. 3.7, which shows the results of tests conducted by BSC for ten years in an industrial district of Sheffield. Figure... 

The results of tests on copper alloys have been given by Tracy , Thompson , Mattsson and Holm and Scholes and Jacob , the first two of these investigations being made under the aegis of the American Society for Testing and Materials. The tests of Tracy, and Scholes and Jacob were both for periods up to 20 years in those of Thompson, and Mattsson and Holm specimens have been removed after 2 years and 7 years and further specimens remain exposed for removal after 20 years. The numbers of materials tested are given in Table 4.11 they included brasses, nickel silvers, cupro-nickels, beryllium coppers and various bronzes. Mattsson and Holm tested 14 alloys in the form of rod in addition to the sheet materials, the results for which are given in Table 4.11. 

Temperature Results of tests carried out in the temperature range 250-350°C are not consistent. In one series for example, on extruded beryllium for seven days in distilled water at 270°C, average attack varied between 0-015 and 0-53 mm/y. In contrast, other work on hot-pressed material gave an average attack of less than 0-0025 mm/y. 

Tantalum-Molybdenum Schumb, Radtke and Bever studied the corrosion resistance of tantalum-molybdenum alloys that form a continuous series of solid solutions. The results of tests of up to 500 hours duration (Table 5.26) indicate the corrosion resistance of the alloy to be substantially that of tantalum, provided its concentration exceeds 50%.

In the gas-cooled reactor, reaction.between the coolant and the moderator results in formation of a proportion of carbon monoxide in the atmosphere. This gas can be carburising to nickel-base alloys but the results of tests in which CO2 was allowed to react with graphite in the furnace indicate that the attack on high-nickel alloys is slight, even at moderately high temperatures and is still mainly due to simple oxidation. 

Soil Galvanised pipe is frequently used for underground water services. Table 13.10 gives results of tests carried out with galvanised pipes and plates buried at different sites. 

A weld bead included in a test-piece is, to some extent, peculiar to itself and may not necessarily be representative of nominally similar welds to be made by other welders under other circumstances. To this extent, results of tests on welds must be subject to some qualification in interpretation, having in mind that what will be disclosed principally will be the overall ability of the composition of the weld metal to resist the corrosive environment. In some cases, entrapped flux, craters, fissures, folds, surface oxides etc. may introduce localised corrosion that may or may not occur with all welds of the type studied (see Section 9.5). 

Rates of corrosion rarely remain constant with time. More often than not, rates of attack tend to diminish as a result of the formation of adherent insoluble corrosion products or other protective films originating in the environment (Fig. 19.1). Therefore, extrapolation of results of tests that are too short is more likely to indicate a tower resistance to attack than will... 

In applying results of tests on small specimens to estimating corrosion, particularly by pitting on large structures, the effect of the increased area in increasing the depth of pitting must be taken into account . 

Maher draws attention to the 1874 paper of Lecoq de Boisbaudran in which he announced the discovery of gallium, the first of Mendeleev s predictions to be confirmed. And this is, indeed, an important paper. One possible misconception should, however, be quashed immediately. De Boisbaudran did not discover gallium as a result of testing Mendeleev s prediction. Instead he operated quite independently by empirical means in ignorance of Mendeleev s prediction and he proceeded to characterise the new element spectroscopically. De Boisbaudran s findings were published in the Comptes Rendus. 

Underwriters Laboratories (UL) Test 94 can be used. The placement of the specimen, the size of the flame, and its position and location with respect to the specimen are described in detail in this important UL specifications. Depending on their nonburning to burning capabilities, results of tests are reported as being materials classed 94V-0, 94V-1, 94V-2, 94-5V, etc. (Chapter 2, HIGH TEMPERATURE, Flammability). 

The results of test samples taken 4 hrs after firing, using the four major brands of 0.22 cal ammo available in the Eastern USA are shown in Table 11. These measurements demonstrate that... 

The results of tests on the polymers A, B, C, D are plotted versus the absolute temperature in Fig. 3.1 in order to facilitate comparison with Eq. 3.1. Tests on polymer E were spoilt by plastic deformation. Straight lines were drawn through the points in Fig. 3.1 and through the origin (T = OK). Such lines correspond with the Eq. (3.1). At temperatures below the glass transition where the polymers...

Testing must be conducted in a typical end-user environment, or in a simulated end-user environment, identical with the environment where the software/computer system will be used. Documentation of testing can be recorded as raw data, such as in a logbook, and should include the parameters tested, and the results of testing. The data should be tabulated as a final report document that includes all details included in the test plan, their execution, the results, and conclusions. The final report document must be signed by appropriate personnel, reviewed as needed, and archived. Upon successful completion of testing, the software/computer system can be released for testing and use in an actual end-user environment.
