Hartley HO (1950) The maximum F-ratio as a short cut test for heterogeneity of variance. 

An acceptable middle way is to cut test pieces from the product. This has the advantage that the properties measured relate to the material as processed in the factory rather than to test pieces prepared under laboratory conditions. The only disadvantage is the limitation in obtaining suitable test pieces from many products. 

When using test pieces to give an indication of product performance, it is preferable to cut test pieces from the product.

Brisance by Lead Plate Cutting Test. When using the proc described in ChemMetEngrg 26,1126—32(1922) and exploding a sample compressed at2320psi(l63 l kg/cmJ), pentryl cuts a hole in the plate equal in size to that made by tetryl and slightly larger than PA or TNTfRef 4,pp 1387-8) (See also Ref 8a)...

By applying short-cut test systems in combination with suitable concentration methods, the source of mutagenic pollution can be traced and sanitation measures can be envisaged. 

The first requirement is that the test piece should be dimensionally accurate but this is not dealt with in ISO 23529, the necessary tolerances and dimensions remaining a subject for the individual test method. The important dimensions can be conveniently checked on a cut test piece using a projection microscope, but the dimensions of the cut test piece will not necessarily be identical with the dimensions of the die because of the pressure of the blade deforming the rubber. In the majority of tests it is the test piece dimensions which are those specified. 

ASTM D318316 deals only with cutting test pieces from rubber that is not in the form of sheets, but the content is very similar to the relevant parts of ISO 4661, covering slicers, skiving machines, buffing wheels and abrasive bands. Apparently, buffing wheel apparatus is known as an Emerson type rubber buffer in the USA, presumably after a manufacturer. 

The test piece specified is a cylinder 29 0.5 mm diameter and 12.5 0.5 mm thick which can be used bonded or lubricated, in the former case the rubber can be directly bonded to metal plates or adhered later. Although cutting of the test piece, as opposed to moulding, is allowed, it is debatable as to whether cut test pieces can be readily produced with sufficient precision. In addition to the standard test piece, provision is made for using the product or a part of it but for some curious reason only under lubricated...

Majrich Sorm (Ref 14, p 338) give brisance values based on the lead plate cutting test on other brisance tests. They compare these values with those calcd by Kast s formula. Their lead plate cutting test data showed si higher brisance values for RDX than for PETN... 

Figure H2.2.4 A force/determination curve illustrating a wire cutting test (10 mm/min deformation rate) for cheddar cheese using a single-wire sectilometer at room temperature.

Select a deformation rate of 22.86 cm/min (9 inches/min) for the Wamer-Bratzler test. For the Kramer shear cell test or the wire cutting test, select a desired deformation rate.

Bell s inequality provides a clear-cut test of local reality vs. quantum mechanics. The unambiguous answer, from a variety of experiments which we describe in the next section, is that quantum mechanics wins Thus, we can conclude that we live in a Universe which does not respect local reality. Quantum entanglement—a term introduced by Schrddinger—really happens In drawing this conclusion we are actually glossing over a number of still-unresolved hair-splitting metaphysical arguments. This remarkable result is often summarized as Bell s theorem ...
