The index of refraction of transparent plastics may be determined by placing a drop of a specified liquid on the surface of the polymer before measuring the index with a refractometer. An optical microscope is used to measure the index of refraction in an alternative method (ASTM-D542). [Pg.44]

There are five submethods in the test (ASTM D-611, IP 2) for the determination of the aniline point (1) Method A is used for transparent samples with an initial boiling point above room temperature and where the aniline point is below the bubble point and above the solidification point of the aniline-sample mixture (2) method B, a thin-film method, is suitable for samples too dark for testing by method A (3) methods C and D are used when there is the potential for sample vaporization at the aniline point (4) method D is particularly suitable where only small quantities of sample are available and (5) method E uses an automatic apparatus suitable for the range covered by methods A and B. [Pg.90]

With the introduction of ultraviolet absorption procedures (ASTM D-2008, ASTM D-2269), the test finds less use but still provides a useful method to determine possible contamination of mineral oil with impurities transparent to both visible and ultraviolet light and hence not detectable by color or by ultraviolet absorption measurements. [Pg.254]

The cloud point is the temperature at which a cloud of wax crystal first appears in a liquid when it is cooled under conditions prescribed in the test method. This test method covers only petroleum oils that are transparent in layers 38 mm (1.5 in.) in thickness, and have a cloud point below 49°C (120°F). The cloud point is an indicator of the lowest temperature of the utility of an oil for certain applications, and it is usually higher than the pour point (ASTM D-97, ASTM D-5853, ASTM D-5949, ASTM D-5950, ASTM D-5985, IP 15). [Pg.255]

Additional opportunities in the styrene plastics industry exist for the development of products having such unique properties as high heat resistance and optical transparency. Arco produces the Dylark family of heat-resistant styrene plastics, which are copolymers of styrene-maleic anhydride. These products have a good balance of mechanical properties and have a heat distortion (under ASTM D68) of 234 F (33) which is markedly higher than homo polystyrene. [Pg.378]

Haze and Luminous Transmittance ASTM D1003 provides two methods for measuring light transmittance and haze in planar sections of transparent plastics. The method making use of a hazemeter is briefly described. [Pg.928]

ASTM D542 describes two methods, viz., i) refractometric and ii) microscopic, for the measurement of refractive index of transparent organic plastics. Both the methods require optically homogeneous specimens of uniform index. The ASTM recommends that refractometric method is to be... [Pg.929]

ASTM D1044, Resistance of Transparent Plastic Materials to Abrasion. [Pg.134]

Abrasion resistance is a difficult property to define as well as to measure. It is normally accepted that abrasion resistance depends on the polymer s hardness and resilience, frictional forces, load, and actual area of contact. ASTM D1044 evaluates the resistance of transparent plastics to one kind of surface abrasion by measuring its effects on the transmission of light. Another test method to evaluate abrasion, ASTM D1242, measures the volume lost using two different types of abrasion machines loose abrasion and bonded abrasion. [Pg.88]
