Application-Specific Testing

This shows that an SILP catalyst can be potentially optimized by a linear combination of beneficial effects that is, by tweaking different variables in the systems independently in combination, a certain improvement in activity can be achieved. 

After the catalyst was successfiiUy optimized in terms of activity, questions regarding its applicability in industrial conditions arose.

Beyond the general physical and chemical characterization of dispersions and polymer films, a large number of application-specific tests exist. In this chapter,... 

Hydro projects, dams, bridges, naval equipment and any installations that aie prone to continuous shocks and vibrations also require their primary and secondary systems to have a better design and operational ability to withstand seismic effects or other ground/surface vibrations. No specific tests are presently prescribed for such applications. But response spectra can be established even for such locations and the primary and secondary systems analysed mathematically or laboratory tested. 

As should be apparent from the variety of applications, there are many test methods for hot melts, most of which are application specific. Many such tests were developed by adhesive suppliers and are proprietary to them. The use of standardized testing is most common for PSA tapes and labels. These tests are discussed elsewhere in this volume. 

Type II Flame arresters acceptable for in-line applications. Type II arresters shall be specifically tested widi the inclnsion of all pipes, tees, bends, cowls, weather hoods, etc., which may be fitted between die arrester and the atmosphere. Owing to the prohibitive cost of testing deflagration flame arresters for each particular installation, the Type II (in-line) category is generally not enconntered. 

Guidance on specifications is divided into universal tests/criteria which are considered generally applicable to all new substances/products and specific tests/criteria which may need to be addressed on a case-by-case basis when they have an impact on the quality for batch control. Tests are expected to follow the ICH guideline on analytical validation (Section 13.5.4). Identification of the drug substance is included in the universal category, and such a test must be able discriminate between compounds of closely related structure which are likely to be present. It is acknowledged here that optically active substances may need specific identification testing or performance of a chiral assay in addition to this requirement. 

At times, unexpected events delay application of the test substance after the spray solution has been prepared. Most test substance spray solutions are stable for a reasonable period of time. However, the protocol, SOPs, specific test substance guidance... 

The need for complete compositional analysis of additive packages in industrial plastics for both research and quality control applications has led to the development of numerous analyte-specific test procedures in recent years. 

Orchid Cellmark is focused on identity DNA testing services for both, human and agriculture applications. Specifically, in the DNA testing services are used for food safety and selective trait breeding in the agriculture industry. The patented SNP method employs DNA polymerase for carrying out the biochemical reactions, which lead to the identification of the SNP by isolating the site of a suspected SNP. 

The background to this set of requirements has already been discussed in Chapter 2. It should be remembered that GLP relates to a study and not to specific tests. In fact, in some respects, it is very narrow in its scope of application as it is only a requirement for regulatory studies. The definition of a regulatory study was given in Chapter 2. A nominated monitoring authority will judge compliance... 

Application of the analytical techniques discussed thus far focuses upon detection of proteinaceous impurities. A variety of additional tests are undertaken that focus upon the active substance itself. These tests aim to confirm that the presumed active substance observed by electrophoresis, HPLC, etc. is indeed the active substance, and that its primary sequence (and, to a lesser extent, higher orders of structure) conform to licensed product specification. Tests performed to verify the product identity include amino acid analysis, peptide mapping, N-terminal sequencing and spectrophotometric analyses. 

This Chapter includes the requirements for inspections by owner, quality control examinations, nondestructive examinations, and specified tests by the construction organization (manufacturer, fabricator, or erector). Inspection, examination, and testing shall be in compliance with the general requirements of Chapters GR-4 and GR-6, as well as the applicable specific requirements in this Chapter and engineering design. 

In addition to the functional tests common to any application, the TPEs that are proposed for medical applications must satisfy certain specific tests of biocompatibility and aptitude for sterilization. 

Second, the emphasis on empirical modeling leads to chemometrics being a highly interfacial discipline, in that specific tools are often developed with specihc applications already in mind. For example, specific chemometric tools have been developed to align retention time axes in chromatograms [20] and to preprocess diffuse reflectance data [21]. In contrast, other disciplines, such as statistics, are associated with well-defined stand-alone tools (ANOVA, f-test, etc.) that can be applied to a wide array of different applications. One consequence of this interfacial property of chemometrics is that one must often sift through a very large toolbox of application-specific tools in order to find one that suits a particular application. 

Where relevant, a statement ofcompliance/non-compliance with requirements andfor specifications where applicable, a statement on the estimated uncertainty of measurement information on uncertainty is needed in test reports when it is relevant to the vaficfty or application ofthe test results, when a customer instruction so requires, or when the uncertainty affiects complianceto a specifcation limit ... 

Part AM This part lists permitted individual construction materials, applicable specifications, special requirements, design stress-intensity values, and other property information. Of particular importance are the ultrasonic-test and toughness requirements. Among the properties for which data are included are thermal conductivity and diffusivity, coefficient of thermal expansion, modulus of elasticity, and yield strength. The design stress-intensity values include a safety factor of 3 on ultimate strength at temperature or 1.5 on yield strength at temperature.
