Quality control storage considerations

If computer-integrated resin handling systems are considered, one must compare their operating procedures with one s process requirements. These process requirements describe the flow of resin and product through the system, which determines the system s electronic architecture. Pertinent considerations include batch vs. continuous operations, the type and number of conveying lines, resin storage and distribution, quality control means and procedures, inventory control, the type and quantity of process parameter sensors, the type and quantity of controlled devices, modes (automatic, semiautomatic, manual, and/or shutdown modes), process information, process management controls, and centralized vs. local operation (Fig. 9-1). 

In addition to the basic negotiation of costs and quantities of pipe to be supplied, the relationship between pipe maker and pipe user may involve other market related factors. Technical support may be required in terms of material selection, application of technical standards and provision of quality control test services. Transport to the site of use may involve restrictions in terms of vehicle size or times of delivery. This is particularly so when pipes are being laid below busy city streets or in remote rural locations. Pipe storage areas near the site may be limited and this then implies smaller, more frequent deliveries. Such practical considerations may have a significant bearing on the delivery price of pipe. 

The Standard considers that an effective quality system should comprise management responsibility quality system principles quality system audits quality/cost considerations raw material quality control inspection and testing control of non-conforming product handling, storage, packaging and delivery after sales service quality documentation and records personnel training product safety and liability and statistical data/analyses. 

Chemicals should be stored within the temperature range recommended by the manufacturer. Proper temperature control may be important for product quality and can also have an impact on the safe storage of these materials. While this consideration should apply in general, some classes of chemicals have special needs.
