Test Part Three

Table 1 is condensed from Handbook 44. It Hsts the number of divisions allowed for each class, eg, a Class III scale must have between 100 and 1,200 divisions. Also, for each class it Hsts the acceptance tolerances appHcable to test load ranges expressed in divisions (d) for example, for test loads from 0 to 5,000 d, a Class II scale has an acceptance tolerance of 0.5 d. The least ambiguous way to specify the accuracy for an industrial or retail scale is to specify an accuracy class and the number of divisions, eg. Class III, 5,000 divisions. It must be noted that this is not the same as 1 part in 5,000, which is another method commonly used to specify accuracy eg, a Class III 5,000 d scale is allowed a tolerance which varies from 0.5 d at zero to 2.5 d at 5,000 divisions. CaHbration curves are typically plotted as in Figure 12, which shows a typical 5,000-division Class III scale. The error tunnel (stepped lines, top and bottom) is defined by the acceptance tolerances Hsted in Table 1. The three caHbration curves belong to the same scale tested at three different temperatures. Performance must remain within the error tunnel under the combined effect of nonlinearity, hysteresis, and temperature effect on span. Other specifications, including those for temperature effect on zero, nonrepeatabiHty, shift error, and creep may be found in Handbook 44 (5). The acceptance tolerances in Table 1 apply to new or reconditioned equipment tested within 30 days of being put into service. After that, maintenance tolerances apply they ate twice the values Hsted in Table 1. Table 1 is condensed from Handbook 44.

Wljat If" 2. Choosing, An Incoirect Rank. The performance of the class C SIMCA model. pre f ously determined to be a rank three model, is examined using a rank of two. A rank three SIMCA model appropriately includes class C samples and excludes class A and B samples. WTien a rank two SIMCA model is estimated, two class C test samples are incorrectly excluded. An examination of reveals that the distance term is zero and the PCA residual is the only contribution. This indicates a modeling problem. When this SIMCA model is applied to the class A and B test samples, three and eight samples are incorrectly included as part of class C, respectively. [Pg.263]

Lignin was chemically modified prior to resinification, and the effect of phenolation was examined on the gluability of the resol resin adhesives (23). The phenolation was performed either with HC1 (80°C, 60 min) or without catalyst (200°C, 60 min). Prior to adhesive testing with three-ply plywood, 5 parts of coconut husk powder were mixed with 100 parts of the resin. [Pg.492]

For vial filling machine parts, three heat penetration studies were performed and found satisfactory including microbiological challenge test. The results of exposure time temperature, minimum lethality, and microbiological challenge test met the acceptance criteria. See Table 3. [Pg.674]

Therefore, we prepared and tested compressed three-layer tablets, covered on all surfaces, except for one part of the first dose, with an impermeable coating. We employed ibuprofen as a model drug, hydroxypropylmethylcelluloses as components of the control barrier and some superdisintegrants as the energy source [13]. [Pg.81]

A transmission signal measured on a flowing suspension of particles shows significant fluctuations which contain complete information on particle size and concentration. Details have been published in three parts [90-92]. In parts one and two the basic properties were studied for a beam of uniform intensity. The theoiy was extended in part three to a Gaussian beam with experimental tests to follow. [Pg.539]

The test site, shaped like an irregular polygon and familiarly called the polygon, is a 19,000 km" zone in the northeast of the newly independent Republic of Kazakhstan, 800 km north of the Kazakh capital Alma-Ata. The zone lies southwest of the Irtysh River which flows into Kazakhstan from China and which for a short stretch, where it veers sharply northwards on its way to join the Ob River in Siberia, forms part of the polygon boundary (see Fig. 10.16). The USSR conducted 465 nuclear tests at three locations called technical areas within the polygon over a period of 40 years (1949-1989) for military and peaceful purposes. [Pg.525]

As part of the project work plan, this protocol was tested in three case studies designed to match the three levels of vafidation, before preparation of the final version. The interlaboratory studies included analyses of i) selected natural and synthetic oestrogens and oestrogenic activity in wastewater, ii) pharmaceuticals in water and iii) brominated flame retardants in dust. The design of the interlaboratory studies, analytical protocols and final reports from the interlaboratory studies are available on the project web site. The final aim is flie implemenfation of the protocols in the fields of European standardisation and European legislation. To this purpose, negotiations will be initiated to launch New Work Item proposals at CEN level (see Eigure 8.1.5). [Pg.366]

A special three- (or six-) element strain gauge rosette is installed on the test part at the point where residual stresses are to be determined. [Pg.366]

These sections, 40.225 What form is used for an alcohol test , and 40.227 May employers use the ATF for non-DOT tests, or non-DOT forms for DOT tests , specify the form to be used for all DOT-required alcohol tests the three-part DOT Alcohol Testing Form (ATF). [Pg.173]

Plastics are susceptible to flaws that cannot always be seen thus premature failure can only be prevented if methods are available that will disclose the presence and extent of such flaws without destroying the part. Three of the more common nondestructive testing methods are ultrasonic, -radiometric, and holographic testing. [Pg.368]

Part one consisted of a limited PRA to determine the potential for EFW system failure under various loss-of-main-feedwater transient conditions, with particular emphasis being placed on determining potential failures from human errors, common causes, single-point vulnerabilities, and test and maintenance outages. This evaluation applies to operating plants and plants under construction and not to advanced or future plants. Part two was composed of a deterministic review of the EFW system using the acceptance criteria of SRP Section 10.4.9 and the associated Branch Technical Position (BTP) ASB 10-1. Part three required a re-evaluation of the decay heat removal capability of the EFW system with respect to EFW system flowrate. Parts two and three apply to advanced or future plants. [Pg.343]

Table 17.3 a-c Results of comparative study between contact angles and ink tests for three untreated and plasma-treated plastics (PDMS, PVC, PET). As the interpretation of ink tests is partly user dependent this table also shows images of relevant brush strokes. [Pg.431]

Whether the worker-firm relationship is associated with hazard rate differentials is tested by three variables job size (i.e. hours worked per week), flexible hours and tenure. Estimates indicate that ceteris paribus the hazard rate tends to decrease with increasing job size. That is, part time workers have higher hazard rates than full timers. See Figure 2. [Pg.1341]
