When a test run is performed using the actual materials for the toll, it is a prime opportunity for the toller and the client to document the capability of the equipment, instrumentation, and process steps. During such a test, frequency of sampling may be increased, additional analyses performed and yield capabilities checked to find the optimum setpoints and timing for the toll process. Health, safety and environmental staff may choose to provide close coverage of the test run to evaluate areas for improvement during the actual startup and long term operation. 

Critical Equipment Equipment, instrumentation, controls, or systems whose malfunction or failure would likely result in a catastrophic release of highly hazardous chemicals, or whose proper operation is required to mitigate the consequences of such release. (Examples are most safety systems, such as area LEL monitors, fire protection systems such as deluge or underground systems, and key operational equipment usually handling high pressures or large volumes.)... 

Equipment, facilities, supplies, tools, and utility services (e.g., PPE, sampling equipment, instrumentation, hot/cold water, electricity, sewage treatment). 

A PHA analyzes potential eauses and eonsequenees of fires, explosions, releases of toxie or flammable ehemieals, and major spills of hazardous ehemieals. The PHA foeuses on equipment, instrumentation, utilities, human aetions (routine and nonroutine), and external faetors that might affeet the proeess. 

The vessels, pipes, equipment, instrumentation, procedures and practices for the FMFA are identified and understood to establish the scope and level of detail. The PSM Rule requires FMEAs to be performed at the major component level - a trade-off between the time to perfonu the analysis and its value. 

This report addresses ammonia plant shutdowns over the listed time period in 40 countries. It provides a basis for comparing plant performance area by area leading to better control of reliability efforts while reducing maintenance and unplanned shutdown costs. Data are presented for shutdowns due to power, equipment, instrumentation, feedstock and product inventory control.

Certain commercial equipment, instruments, or materials are identified in this report to specify adequately the experimental procedure. Such identification does not imply recommendation or endorsement by the National Institute of Standards and Technology, nor does it imply that the materials or equipment identified are necessarily the best available for the purpose. 

The two types of lines on a flowsheet are (1) those representing outlines and details of equipment, instruments, etc., and (2) those representing pipe carrying process or utility liquids, solids, or vapors and electrical or instrument connections. The latter must be distinguished among tliemselves as suggested by Figure 1-21. 

After an area classification has been established, then anelectrical equipment, instruments, and wiring must adhere to that classification. Therefore, some motor enclosure types would not be electrically acceptable for specific area classifications. 

Different research frontiers require different mixes of support mechanisms. The appropriate mix for a particular area depends on several of factors, including the nature of the scientific area its requirements for expensive equipment, instruments, or facilities and the need for trained personnel from that area in the broader economy. 

Is the application or system an integral part of the equipment/instrumentation used in testing, release, and/or distribution of the product/samples ... 

Assemble the chemicals, equipment, instrument, etc. Arrange to get samples of the material to be analyzed, or better yet, go and perform the sampling yourself. Perform the preliminary physical or chemical treatment needed for the samples, standards, and blanks. 

Statistical Control for a New Method To implement a new method, a laboratory must produce a preliminary track record of its success so that quality control charts can be established and then maintained. Aside from acquiring the space, supplies, equipment, instrumentation, and manpower required, the method must be tested, modified, tested again, etc., until it is ready to go "online." Gillis and Callio (listed in Bibliography) recommend the following sequence for preparing an instrumental method for routine use. 

The cost of reactor including installation, auxiliary equipment, instrumentation, overhead, labor, depreciation, etc., is m = 0.01/h liter. 

Key test and equipment instrumentation pre- and postcalibration status supporting each function... 

Calibrate process equipment instrumentation on a regularly scheduled basis and after repairs. 

Vendor specifications are used as acceptance criteria for operational qualification of equipment. Vendors typically define specifications for analytical equipment instruments such that they can be met easily at the time of installation. However, these specifications are so stringent that problems arise after a period of usage of the instruments, and requalification tests fail. 

The identification and promulgation of best analytical practices including sampling, equipment, instrumentation and materials.

SRM 705 is the narrow molecular-weight-distribution sample the other SRM 706, by contrast, is a broad molecular-weight-distribution polymer, the result of a thermal polymerization which more closely resembles commercially available polymers. Both of these were supplied by the Dow Chemical Co. (Certain commercial equipment, instruments, or materials are identified in this paper in order to specify adequately the experimental procedure. In no case does such identification imply recommendation or endorsement by the National Bureau of Standards, nor does it imply that the material or equipment identified is necessarily the best available for the purpose.)... 

Calibration. Prior to the initiation of testing, all equipment, instruments and interconnects should be calibrated.
