Techniques for evaluating processing stabiHty and mechanochemical effects include using a Brabender torque rheometer (29,30), injection mol ding (26,28), capillary rheometry (26,28), and measuring melt index as a function of residence time (26). 

Initial evaluations of chemicals produced for screening are performed by smelling them from paper blotters. However, more information is necessary given the time and expense required to commercialize a new chemical. No matter how pleasant or desirable a potential odorant appears to be, its performance must be studied and compared with available ingredients in experimental fragrances. A material may fail to Hve up to the promise of its initial odor evaluation for a number of reasons. It is not at all uncommon to have a chemical disappear in a formulation or skew the overall odor in an undesirable way. Some materials are found to be hard to work with in that their odors stick out and caimot be blended weU. Because perfumery is an individuaHstic art, it is important to have more than one perfumer work with a material of interest and to have it tried in several different fragrance types. Aroma chemicals must be stable in use if their desirable odor properties are to reach the consumer. Therefore, testing in functional product appHcations is an important part of the evaluation process. Other properties that can be important for new aroma chemicals are substantivity on skin and cloth, and the abiHty to mask certain malodors.

Quantitative risk analysis (QRA) is a powerful analysis approach used to help manage risk and improve safety in many industries. When properly performed with appropriate respect for its theoretical and practical limitations, QRA provides a rational basis for evaluating process safety and comparing improvement alternatives. However, QRA is not a panacea that can solve all problems, make decisions for a manager, or substitute for existing safety assurance and loss prevention activities. Even when QRA is preferred, qualitative results, which always form the foundation for QRA, should be used to verify and support any conclusions drawn from QRA. 

The American Chemistry Council, formerly the Chemical Manufacturers Association (CMA), and the American Institute of Chemical Engineers Center for Chemical Process Safety (AIChE/CCPS) have jointly published Evaluating Process Safety in the Chemical Industry User s Guide to Quantitative Risk Analysis. This is a revised and updated edition of Evaluating Process Safety in the Chemical Industry A Manager s Guide to Quantitative Risk Analysis, published in 1989 by CMA. 

When considering the possibility of using internal combustion drivers, evaluate process requirements and costs. If a low-cost, gaseous fuel is available, gas engines and gas turbines may surpass other drivers in economical installation and operation. In the initial process design stage, a method of establishing the cost of purchase, installation, and operation for drivers is needed. 

Once the candidate corrective measure alternatives have been identified, a more detailed evaluation of each alternative needs to be undertaken. From an engineering perspective, the first step in the evaluation process would include the development of a conceptual design for each alternative. The conceptual design would consist of a process description, a process flow diagram and a layout drawing. Preliminary sizing of equipment and utility and land requirements would be developed. In addition, chemical requirements and residuals produced can be estimated. From the conceptual design, permitability and residuals disposal issues can be identified and addressed. 

Process Hazards Analysis (PrHA) - The application of analytical methods to identify and evaluate process hazards to determine the adequacy or control. 

Like VDA 6.1, AVSQ 94 does not include the requirements of ISO 9001. In this way issues of copyright are overcome, a practice shared by VDA and EAQF but not QS-9000. However, unlike VDA 6.1, AVSQ 94 follows the 20 elements of ISO 9001 with two additional elements, covering financial considerations and product safety. Those questions that go beyond ISO 9001 are marked and as every question is numbered it simplifies the evaluation process. A scoring method is employed to classify organizations in terms of a conformity index. Each question is awarded a point (0, 2.5, 5, 7.5, or 10), where 10 points means full compliance, 7.5 points means minor inadequacies, 5 points means inadequacies in application requiring improvement, 2.5 points means serious inadequacies in application, and 0 points is used for criteria not applied. Unfortunately all questions carry the same weight as no account of the impact of omission on product quality or customer satisfaction is included. 

The evaluation process, which starts with the request to purchase and ends with the placement of the order or contract. This is covered by clause 4.6.2 of ISO/TS 16949. 

The areas that may be considered as part of such an evaluation are the performance-influencing factors (PIFs) described in Chapter 3. The human factors assessment methodology (HFAM) method described in Chapter 2, provides a systematic framework for the evaluation process.

The health risk evaluation process consists of four steps hazard identification, dose-response assessment or hazard assessment, exposure assessment, mid risk cliaracterization. 

The risk evaluation process defines the equipment, hazards, and events leading to an accident. It detennines the probability tliat an accident will occur. The severity and acceptability of the risk are also evaluated. 

NOTE In practice, the skills required to correctly and comprehensively interpret the various water analyses and provide suitable recommendations for action are not widely available outside the ranks of the service companies. When selecting a water treatment service provider therefore, this element should factor significantly in the vendor evaluation process. 

To obtain the most complete and accurate picture, both formative and summative evaluation should be carried out. Furthermore, as many people as possible should be consulted as part of the evaluation process, including mentors, mentees...

Knapp (1998) has noted that there is a need to know if additional treatment costs have a downstream pay-off in system-wide cost-effectiveness. This is almost certainly the case for clozapine, but it is less clear for other drugs. Knapp (1998) argues that cost-effectiveness studies need to be part of the initial evaluative process rather than an afterthought. In this respect very new drugs may have an advantage as these calculations can be built into the current registration...

Results of regression are given in Table 7.4-4. The cycle time is size-dependent whereby this dependency is stronger for the semicontinuous process at these particular process conditions. The exponent p is almost the. same for both processes and is approximately 1/3. Clearly, the physical properties of the reaction mixture and thermokinetic data are needed to evaluate processing times and cycle times at a large scale.
