Note that the first condition is the familiar Shewhart chart limits. Pattern tests can be used to augment Shewhart charts. This combination enables out-of-control behavior to be detected earlier, but the false-alarm rate is higher than that for Shewhart charts alone.

Resistance R of the patterned test area is measured by a 4-point probe and total sample height, hf, is determined by direct measurement, for example by profilometry or microscopy. 

The search for small isolated sites of erosion or corrosion can sometimes become like looking for the needle in the haystack. An isolated thin area can be easily missed or skipped over depending on the density of the examination pattern. Testing the thickness of higher temperature metals over approximately 180° F usually requires special transducers and couplants (liquid or gels between the probe and the metal used to bridge the air gap). 

Formulations with a S/A binder base show a stability which always increases in the open air after 7 days. This is not the case with the corresponding pure asphalt base formulations. This improvement continues, following a regular pattern. Tests were not sufficiently numerous to define the period at the end of which, in all cases, measurement stability is obtained. But it is already known that the increase in stability value with time can be substantial. 

Special tests are needed for memory devices to insure the integrity of every memory bit location. These functional tests are composed of four basic tests, pattern tests, background tests, timing test, and voltage level tests. A summary of these tests is contained in Table 7.11. 

March An N pattern test that checks for functional cell failures (opens and shorts and address unique faults) and data sensitivity In this test a background of Os is written into memory. Then a 1 is written into each sequential cell. Each cell is then tested and changed back to 0 in reverse order until the first address is reached. The same sequence is then repeated by loading in a background of 1 s. 

Masest An N pattern test that checks for address uniqueness and address decoder problems (open decode lines). This is an alternating Multiple Address Selection test that writes a background of Os to the memory device at the min address, then the max address, then the min +1 address, then the max — 1 address, etc. All cells arc then read and verified and a complementary pattern of Is is read into the memory device and the test is repeated.

Zeros/ones An N pattern test. A background of either solid Is or Os is stored in each cell. 

The purchasing of batteries in use by Deutsche Telekom takes place over framework contracts. Through these it is guaranteed that only released batteries and released battery accessories are delivered to the Telekom. Further deliveries can be abandoned if there are problems with a certain product within a short time. The acceptance of the delivery to the Telekom is given if proof of the observance of quality handicaps is produced by a type pattern test and regular audits at the manufacturer. Tests of several years that are enforced in the central laboratory of the Telekom in Steinfurt are prerequisite for the transaction of the type pattern test. The quality handicaps are worked out in a form of technical delivery conditions for the individual series. It is important on this occasion that no particular products are... 

In the past, each battery to be used at the Telekom was designed for production and the manufacture process was pursued. In the course of globalization of the markets, this expenditure is no longer justified. As well, the product itself stood in the center of the design planning with the enforced type pattern test. Today, very much time is spent on the examination of production conditions. On the basis of...
