Products and Materials

The working capital includes the cost of inventories, such as raw materials, materials-in-process, products, etc as well as suppHes, accounts receivable less accounts payable, prepaid expenses, other cash needs such as payroll, and some start-up expenses, eg, materials and wages. Typical inventories can be taken as one month s supply of raw materials, products, and materials-in-process. The materials-in-process can be valued at one month s sales. Other operating cash can be estimated as the actual cash need for one month. 

Segregation may also be necessary in the packaging of products not only to prevent visible damage but electrical damage, as with electrostatic-sensitive devices. Segregation may be the only way of providing adequate product identity, as is the case with fasteners. While a well-equipped laboratory can determine the difference between products and materials the consumer needs a simple practical method of identification and labeled packets are often a reliable and economic alternative.

There are different items that have warranties such as equipment, products, and materials. Fulfillment of warranties tends to be a two-way situation. As an example when one buys equipment, you are not just buying equipment, you are entering into a relationship. This may sound tripe, but it is demonstrably true in the case of capital equipment. The warranty relationship can be defined in writing by the warranty document. It goes into detail as to what the OEM (original equipment manufacturer) seller promises to do in event of equipment failure due to specific causes. It also details the responsibilities of the equipment owner. Sometimes the expectations of the processor and OEM are seriously mismatched. 

A major force behind this evolntion will be the explosion of new products and materials that will enter the market dnring the next two decades. Whether from the biotechnology industry, the electronics industry, or the high-performance materials indnstry, these products will be critically dependent on structure and design at the molecular level for their usefulness. They will require manufacturing processes that can precisely control their chemical composition and stracture. These demands will create new opportunities for chemical engineers, both in product design and in process irmovation. 

The EPS (environmental priority strategies in product design) system was initiated in 1989 by Volvo Automotive Company, IVL Swedish Environmental Research Institute and the Swedish Industry Federation. The current version was developed at the Centre for Environmental Assessment of Product and Material Systems (CPM) [37, 38],...

Every case has to be judged separately, considering the product and material-specific characteristics. 

Again, it is important to point out that the chemical industry provides products and materials that are essential to the U.S. economy and to the so-called good life, the standard of living we presently enjoy. In addition to the economic consequences of a successful homegrown or foreign terrorist attack against chemical industry facilities, there is also the potential of a threat to public health and safety and the environment. 

The Directive covers 23 different product types specified in Annex V of the Directive. These include disinfectants used in different areas, chemicals used for preservation of products and materials, nonagricultural pesticides, and antifouhng products used on hulls of vessels. The Directive will not apply to certain product types already covered by other community legislation, such as plant protection products (PPPs) (Section 2.4.1.7.2), medicines, and cosmetics. 

By a post sintering process including additional sintering aids RBSN can densified to porosities of about 0-5% [538-540] This material, SRBSN, is applied for different wear parts [540]. A comparison of the production and material properties is given in Table 10. 

Evaluation of VOC and SVOC emission potential of individual products and materials under indoor-related conditions and over defined timescales requires the use of climate-controlled emission testing systems, so-called emission test chambers and cells, the size of which can vary between a few cm3 and several m3, depending on the application. In Figure 5.1 the dots ( ) represent volumes of test devices reported in the literature. From this size distribution they can be classified as large scale chambers, small scale chambers, micro scale chambers and cells. The selection of the systems, the sampling preparation and the test performance all depend on the task to be performed. According to ISO, chambers and cells are defined as follows ...

Exempt Radioactive Wastes. The radioactive waste classification system in the United States does not include a general class of exempt waste (see Table 1.1). Rather, many products and materials that contain small amounts of radionuclides (e.g., specified consumer products, liquid scintillation counters containing 3H and 14C) have been exempted from requirements for use or disposal as radioactive material on a case-by-case basis. The various exemption levels are intended to correspond to low doses to the public, especially compared with dose limits in radiation protection standards for the public or doses due to natural background radiation. However, the exemption levels are not based on a particular dose, and potential doses to the public resulting from use or disposal of the exempt products and materials vary widely.

Researchers interested in renewable resources should use the principles listed in Figures 3.1 and 3.2 when designing new processes, products and materials. The principles focus your thinking in terms of sustainable design criteria and have already provided innovative solutions to a wide range of problems, and will ultimately benefit the environment, economy and society (otherwise known as the triple bottom line). 

Small heat source ignition tests generally appear to be very sensitive to the composition of the material and some are therefore ideally suited to serve as a tool for formulation development and quality assurance of fire-retardant-treated products and materials. The equipment is inexpensive, only a small quantity of material is needed, the results are usually reasonably repeatable and reproducible, and a qualified laboratory technician can run many tests in a short time. 

Static smoke chamber methods have major limitations in terms of being indicative of the fire hazard due to smoke toxicity of products and materials in actual fires. As combustion products accumulate in the chamber during a test, the burning behavior of the test specimen may have a significant effect on the level of vitiation (oxygen concentration) and temperature rise in the chamber.

Often, calibration of natural products and materials is a desirable goal. In these kinds of assays, it is usually not feasible to control the composition of calibration and validation standards. Some well-known examples include the determination of protein, starch, and moisture in whole-wheat kernels and the determination of gasoline octane number by NIR spectroscopy. In cases such as these, sets of randomly selected samples must be obtained and analyzed by reference methods.
