Tests process

Another phenomenon is so called two-side filling of one-side closed conical capillaries with liquid [5]. On the one hand the more penetrant is trapped by the defect the wider indication will appear. Contrariwise it is almost impossible to extract a penetrant from the completely filled surface defects by dry developer [6]. In this study we propose the theory of the phenomenon. Besides experimental results of the investigation of two-side filling with various penetrants of conical capillaries are presented. Practical recommendations to optimize liquid penetrant testing process are proposed. 

The solution of (2) gives the range of the values of crack s width, which can be revealed by prescribed product family and conditions of testing process. Minimum value H of this range corresponds to the sensitivity threshold for the case Re > H. 

Diesel Fuel. Eederal diesel specifications were changed to specify a maximum of 0.05% sulfur and a minimum cetane index of 40 or a maximum aromatics content of 35 vol % for on-road diesel. Eor off-road diesel, higher sulfur is allowed. CARB specifications require 0.05% sulfur on or off road and 10% aromatics maximum or passage of a qualification test. Process technologies chosen to meet these specifications include hydrotreating, hydrocracking, and aromatics saturation. 

Other test media and techniques include post-emulsification penetrants, penetrants that form gels resistant to easy removal from entrapments, penetrants that concentrate dye constituents as their carrier Hquids evaporate during test processing, and penetrants that form strippable coatings in the developers. StiU other penetrant systems are formulated for use at abnormally low or high temperatures for special test appHcations. 

While 30 ppm may be acceptable as a maximum probability of occurrence for a failure of low severity, it is not acceptable as severity increases. An example table of FMEA Severity Ratings was shown in Figure 2.20. In the definite return to manufacturer (a warranty return) or violation of statutory requirement region (S = 5 or S = 6), the designer would seek ways to enhance the process capability or else utilize some inspection or test process. Reducing d will reduce occurrence, as indicated by equation 2.11, but inspection or test is of limited efficiency.

As with previous, similar exercises, encourage your team to be creative. Like any sound management system, your PSM system probably creates unexpected side benefits over and above those related spedfically to safety performance. For example, the pilot test may have demonstrated that a new system, once installed, enabled the facility to reduce unplanned downtime with better planning and use of preventive maintenance. Or perhaps the pilot test process itself may have helped improve relations between the facility and corporate staff.

From a practical aspect, when the expression quality control is use, we tend to think in terms of a good or excellent product. In industry, it is one that fulfills customer s expectations. These expectations or standards of performance are based on the intended use and selling price of the product. Control is the process of regulating or directing an activity to verify its conformance to a standard/specification and to take corrective action if required. Therefore QC is the regulatory testing process for those activities that measure a product s performance, compare that performance with established standards/specifications, and pursue corrective action regardless of where those activities occur.

For the reasons mentioned above, the development of miniature test processes becomes increasingly important for such biotransformation reactions [84]. Micro reactors can handle small volumes and process them in a well-defined manner and have been shown to have high test throughput frequencies. Hence waste reduc-...
