Some method of joining parts together is used throughout industry, to form either a complete product or an assembly. The method used depends on the application of the finished product and whether the parts have to be dismantled for maintenance or replacement during service. 

Brenden and Chamberlain (6) measured heat release rate from wall assemblies having fire-retardant-treated studs and gypsum board as interior finish in the FPL fire endurance furnace using three methods (a) the substitution method, by which the amount of fuel required to maintain the ASTM E-119 time-temperature curve for a... 

With a complete set of parameters assembled the process of model construction is finished and the model may be interrogated using the methods described in the subsequent sections. In particular, for the exchange of kinetic... 

Validation in quality systems includes establishment of procedures on how to qualify the equipment and machinery, how to verify the design of products, how to verify the process designed, how to verify the achievement of production procedures, how to validate the process developed, and how to validate the methods for measurement and assay. Validation also requires verification of specifications or acceptance criteria of in-process parameters relating to both raw materials and intermediate (in-process product) and finished products, and verification of acceptance criteria for in-process parameters relating to operating conditions of machinery and equipment. Further, when the medical device is assembled at the user s site, validation includes establishing procedures of how to verify assembly. 

Surface sampling the exterior of finished products, as indicator sites, assembled from purportedly sterile components as they exit the process while still under aseptic conditions, may be a more efficacious method of estimating microbiologic contamination potential than invading the critical production site. This method allows sampling the most critical site adjacen to the product, and more sites may be non-invasively sampled over a longer interval. In addition, this method may substantially reduce the incidence of sampling-induced contamination. 

Best of all he has a wide choice in the method of procurement of electronic apparatus. He may purchase the pans and build a device from scratch." He mav buy a suitable kit and assemble it himself. He may purchase the desired device ready-made. Whatever his choice, he knows that anyone can buy electronic components or finished units without arousing the slightest suspicion. Aside from the professional people utilizing electronics, each city of any size has hundreds of individual experimenters and tinkerers.
