ASTM F2819-24 pdf download,Standard Test Methods for Measurement of Straightness of Bar, Rod, Tubing, and Wire to be Used for Medical Devices. 1.1 This standard ASTM F2819 outlines various testing methods for assessing the straightness of bars, rods, tubing, and wires. These methods are mainly intended for bars, rods, tubing, and wires that have been specifically ordered in a straightened and cut-to-length format. They are also applicable to small diameter tubing and wire that have been specially treated to unwind from a spool in a straightened form. 1.2 These testing methods are relevant for measuring the straightness of round wire...

ASTM D7426-24 pdf download,Standard Test Method for Assignment of the DSC Procedure for Determining Tg of a Polymer or an Elastomeric Compound. 1.1 This testing procedure pertains to the determination of glass transition temperatures (Tg) of materials through the use of differential scanning calorimetry. 1.2 This method is suitable for amorphous materials, including thermosets and semi-crystalline substances with amorphous regions, provided they are stable and do not experience decomposition or sublimation within the glass transition range. 1.3 The standard operating temperature range for this method is from –120 to 500°C, although this range may be extended based on the specific...

ASTM D5084-24 pdf download,Standard Test Methods for Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall Permeameter. The test procedures outlined here are formulated to evaluate the hydraulic conductivity, or permeability, of water-saturated porous materials using a permeameter with a flexible wall, within a temperature range of approximately 15 to 30°C (59 to 86°F). These procedures are applicable to a variety of specimen types, including intact, reconstituted, remolded, compacted, and others, as long as their hydraulic conductivity is below about 1 × 10^6 m/s (1 × 10^4 cm/s), adhering to the head loss criteria specified in 5.2.3....

ASTM D696-24 pdf download,Standard Test Method for Coefficient of Linear Thermal Expansion of Plastics Between 30°C and +30°C with a Vitreous Silica Dilatometer. 1.1 This test protocol is designed for the assessment of the linear thermal expansion coefficient in plastics that have an expansion coefficient in excess of 1 µm/(m·°C), employing a glassy silica dilatometer. The plastics being tested must demonstrate a minimal level of creep or elastic strain rate, or a combination of both, during the test conditions and the forces applied, to guarantee that the measurement accuracy is not adversely affected by these characteristics. 1.1.1 When testing at...
