PENDULUM TEST

For the compounds Hsted, vacuum stabiUty at 100°C, cm gas per g per 40 h, less than 1 friction pendulum test, no explosion. [Pg.20]

There are several other comparable rheological experimental methods involving linear viscoelastic behavior. Among them are creep tests (constant stress), dynamic mechanical fatigue tests (forced periodic oscillation), and torsion pendulum tests (free oscillation). Viscoelastic data obtained from any of these techniques must be consistent data from the others. [Pg.42]

Torsion property As noted, the shear modulus is usually obtained by using pendulum and oscillatory rheometer techniques. The torsional pendulum (ASTM D 2236 Dynamic Mechanical Properties of Plastics by Means of a Torsional Pendulum Test Procedure) is a popular test, since it is applicable to virtually all plastics and uses a simple specimen readily fabricated by all commercial processes or easily cut from fabricated products. [Pg.62]

The popular Izod impact tester can use different size specimens depending on the type of plastic and their method of fabrication. The specimen is usually 1/8 in. x l/2 in. x 2 in. other sizes are also used. Specimens can be notched or unnotched. A notch is cut in a specified manner on the narrow face of the specimen. The sample is clamped in the base of a pendulum testing machine so that it is cantilevered upward with the notch facing the direction of impact. The pendulum is released, and the force expended in breaking the sample is calculated from the height the pendulum reaches on the follow-through. The speed of the pendulum at impact is controlled.

Explosive D is approx 80% as brisant as TNT, as indicated by sand tests, but fragmentation tests in shell have shown it to be about 95% as brisant. Both expls have about the same rate of detonation at a d of 1.56g/cc hence, approx equality of brisance would be expected. The rate of detonation of Explosive D has been found to be somewhat affected, particularly at lower loading densities, by the granulation of the material, but this effect is not pronounced. Its expl strength is 98% that of TNT, as evidenced by the ballistic pendulum test (see below)... [Pg.754]

The Russian word "rabotosposobnost or "capacity of doing work corresponds to Engl "power , while the word "sila (pronounced sceela) means "force and can also be called "strength (See Ref 20, p 644-45 Ref 21, p 92 Ref 22, p 466). For practical determination of "rabotosposob-nost one uses in Russia Trauzl Test (Ref 20, p 647 Ref 22, p 466), as well as Ballistic Pendulum Test and Ballistic Mortar Test (Ref 22, pp 469-74). One can also use the Cratering Test (Ref 22, p 474) and a method based on the measurement of shock pressure (Ref 22, p 475). In the book of Baum et al (Ref 20, p 645) it is stated that "sila (F) can be calcd from the equation ... [Pg.476]

It is to be Qoted that the total effective work capacity of an explosive usually has two resultants — (1) fragmentation and (2) blast effect or the movement of matter. These can be measured separately. As there is no shattering effect in the ballistic pendulum test, this test may be considered to measure total effective work capacity Ref W.H.
