Standard Test Procedures

Effectiveness of these EP oils can be evaluated by a number of laboratory test units such as those shown in Figure 4. While the American Society for Testing and Materials (ASTM) procedures describe a number of standard test procedures (10), the operating conditions and test specimen materials should be chosen to simulate as nearly as possible those in an appHcation. 

Diverse appHcations for the fabric sometimes demand specialized tests such as for moisture vapor, Hquid transport barrier to fluids, coefficient of friction, seam strength, resistance to sunlight, oxidation and burning, and/or comparative aesthetic properties. Most properties can be deterrnined using standardized test procedures which have been pubHshed as nonwoven standards by INDA (9). A comparison of typical physical properties for selected spunbonded products is shown in Table 2.

Other New Methods. Because the values obtained are dependent on the conditions of measurement, standard test procedures are under review by ISO for determination of cold-water solubiUty of water-soluble dyes (38) determination of the solubiUty and solution stabiUty of water-soluble dyes (39) and determination of the electrolyte stabiUty of reactive dyes (40). 

Static performance measurements related to positioner/ac tuator operation are conformity, measured accuracy, hysteresis, dead baud, repeatability, and locked stem-pressure gain. Definitions and standardized test procedures for determining these measurements can be found in ISA-S75.13-1989, Method of Evaluating the Performance of Positioners with Analog Input Signals and Pneumatic Output . 

Performance testing of heat exchangers is described in the American Institute of Chemical Engineers Standard Testing Procedure for Heat Exchangers, Sec. 1. Sensible Heat Transfer in SheU-and-Tube-Type Equipment. ... 

AIChE Standard Testing Procedure for Solids Mixing Equipment, American Institute of Chemical Engineers, New York. 

A standard testing procedure for solids-mixing equipment is available (Ref. 1). This contains details and references pertaining to sampling from solids mixtures for both batch and continuous mixing. 

A standard test probe is not absolutely necessary to monitor the column. Any well-resolved peak in the sample may be used. To use a sample component, baseline data must be established when the column is new and performing well. After establishing that the column is performing properly using the manufacturer s standard test procedure, calculate the assymetry factor, theoretical plates, and resolution of one or more of the sample components. Also note the retention time. This will become the baseline test mix, which will be used for later comparison. 

Being cut from tires, the rubber samples in this work cannot always be studied using standard test procedures. The specific techniques used to measure rubber aging have been described in detail elsewhere and are summarized below [2]. The same techniques have been used to evaluate rubber aging in both field and the laboratory oven-aging studies. For reference. Figure 34.2 shows a diagram of the internal components of a radial-ply tire. 

The majority of the tests were carried out against houseflies, because they are the most commonly used insects in standard test procedures, and they are comparatively easy to rear in the laboratory. 

Efforts have been and are being made to standardize testing procedures for evaluating insecticides (41, 83), but considerable variations still exist in the methods, and results therefrom are not always uniform. 

The determination of steady-state conveying characteristics for a given product and test rig has been the subject of a number of earlier investigations such as Mason et al. (1980) and Mills et al. (1982). A standardized test procedure also has been developed and presented by... 

Using a standardized test procedure (Wypych and Arnold, 1985b), determine test rig conveying characteristics, similar to those shown previously in Figs. 11-13. 

A standard test procedure for determination of CaCC>3 equivalents may be found in the Encyclopedia of Industrial Chemical Analysis, Interscience Publishers Division, John Wiley Sons, New York, vol. 15, p. 230. 

Standard Test Procedure for Flame Coatings Applied to Insulated Cables in Trays, 1993. 

Until recently, the lack of uniformly adopted standard test procedures specifically designed for evaluating modified wood has been little more than an inconvenience indeed, the use of different test methods helps to determine which of the tests adopted may be the most appropriate. Due to the rapid changes in this area, with many commercial processes now being adopted, it is now a matter of great urgency to ensure that the appropriate protocols are agreed at an international level. 

Choosing the level of protection (based on appropriate standard test procedures) that should be provided by fireproofing material for specific equipment, based on the needs analysis. 

Samples for a variety of physical, electrical, and chemical testing can be prepared by simple compression in a platen press, and thoughtful adaptation of standard test procedures allows valid... 

Hardness and Abrasiveness. The abrasiveness of a pigment is not identical to its intrinsic hardness, i.e., the hardness of its primary particles. In practice the Mohs hardness is not therefore a useful indication of the abrasiveness of a pigment. Abrasion rather depends on pigment particle size and shape and is usually caused by the sharp edges of the particles. A standard test procedure for determining abrasiveness does not exist. A method based on the abrasion of steel balls by the pigment is described in [1.12],... 

Standard Reference Materials Certified samples sold by the U.S. National Institute of Standards and Technology (or national measurement institutes of other countries) containing known concentrations or quantities of particular analytes. Used to standardize testing procedures in different laboratories. 

Standard testing procedures 21 have been published, for example on centrifuges, filters, mixers, firer heaters... 

Some of the literature reports of the presence of alkaloids in this family may have resulted from the use of ammonium hydroxide during isolation. This practice has been shown to convert certain of the plant constituents to N-conlaining compounds, which then react as alkaloids in standard testing procedures. 

Normal Temperature. Wherever possible, standard test procedures were used in performing strength and durability measurements (3, 5). A summary of the properties for methyl methacrylate impregnated concrete is given in Table III. 

When the development and validation of the packaging manufacturing process are completed, the standard testing procedures (e.g., ASTM) should be used to ensure sterile medical device package integrity and the sterility of the product after additional production processes.
