After the completion of the balanced acceleration and deceleration runs, the unbalance weight must be placed at the predetermined location and the acceleration and deceleration test repeated using the same recording instrumentation. The results should be compared to the appropriate computer predictions and the API acceptance criteria applied. Acceptance criteria were added in the API 617 sixth edition.

A wide range of analysis instruments, either of the portable or permanently installed type, can be used. The latter will frequently be recording instruments and may have control capabilities. Various principles are employed in analysis equipment, including ...

The burning of a column of delay composition takes place by the passage of a reaction front along the column. The temperature profile of this reaction front can be measured by the use of suitable thermocouples and recording instruments. By analysing the shape of the front it can be shown that the reaction is a solid/solid reaction initiated by thermal conduction of heat through the unreacted material. It follows that to obtain reproducible reaction rates there must be (1) constant amount of solid to solid contact and (2) constant thermal conductivity. 

Besides, the two empty cuvettes (or cells) normally employed for the solution under examination and the reference substance (RS) should have exactly the same spectral features and characteristics. Importantly, when a double bond recording instrument is being employed the solvent cell is always placed in the reference beam.

Despite these limitations, rating scales today are the preferred clinical recording instrument in most areas of psychopharmacology. In order to cancel out the disadvantages, they are often combined with brief case histories or occasionally with symptom lists, which can be prepared individually for each patient.

Another SOP category related to the physical facility is environmental control. All plants must be kept free of rodents and insects. Such an SOP will indicate acceptable materials to be used, precautions to prevent product and personnel contamination, frequency, and area-monitoring procedure. In some operations, such as an area to manufacture sterile products, there are requirements for control of air temperature, humidity, flow rates and patterns, and particulate matter. These SOPs require steps such as checks to be performed, including temperature reading and frequency, maintenance to be performed, such as changing air filters and frequency, recording instrument checks, and calibration, such as for temperature and frequency. A prototype SOP is illustrated in Figure 6.

Operational and maintenance plans should be prepared for the computer system and its associated measurement and control instrumentation. Operational plan review will focus on system reliability, performance, diagnostic records, instrument and system I/O calibration, and the provision of critical data to support the batch record. Procedures for controlling the system (e.g., system management, security, and process operations) should be reviewed to verify that they are current, in place, and being followed. For each procedure required for the system there should be documented evidence that the relevant operatives have been trained in its use. All procedures must be written and approved according to the site procedures for writing and approving SOPs. 

With recorded instrument waveforms, it is not practical to store as many as 256 samples per period for most waveforms, as done in sine wave table lookup oscillators. This would correspond to a very high sampling rate. At 44100 Hz sampling rate, waveforms two octaves above A-440 have about 50 samples per period. To maintain 256 samples per period would require a sampling rate of over 200 kHz, which is impractical due to the expense of the memory required.
