Sticking test

The methods to evaluate PSAs include the rolling ball test (ASTM D3121, PSTC-6, BS EN 1721), loop tack test (ASTM D6195, FINAT Test Method 9, BS EN 1719), and quick stick test (PSTC-S). ... 

PETN. We discuss detonation and wall expansion velocity, along with diameter effect information in unconfined rate stick tests. The detonation velocity of ETN is 99% that of PETN in the same test setup, showing that performance properties are very similar for the two nitrate esters.

This test is similar to the old US BOM Broom Stick test (ca. 1930) and the Mallet test recently developed for use in the UK.

The stick test has been further modified using monoclonal antibodies specific for OA and CTX that are more specific than the sheep antibody (Hokama et al. 1986 Taizo 1987). These monoclonal antibodies are in the process of being evaluated. A preliminary collaborative evaluative study of the rapid enzyme immunoassay stick test has been concluded. Eight of the nine laboratories... 

The techniques that appear to represent the major advance in identifying and detecting ciguatoxic fish are inununochemical methods radioimmunoassay (RIA), competitive enzyme immunoassay (ElA), and enzyme-linked immunosorbent assay (ELISA). Of these, the enzyme immunoassay stick test is the simplest, fastest, most specific, more sensitive, and does not require complicated instrumentation. The problems with this method are its cross-reactivity with other polyether compounds and the limited antibody supply. Attempts to validate the method have been unsuccessful due to the lack of reference material.

This FINGER STICK test gives a good indication of whether the child is at risk for lead poisoning. However, it is simply a screen, not a definitive test. Finger sticks may provide a false-positive result, that is, the test often shows a higher level of lead than is actually present in the blood. This effect can be minimized by careful use of proper sampling technique. 

The false positives occur because of contamination from lead dust on a child s skin or from the environment of the laboratory. If the finger stick test is high, then blood should be drawn from the vein to confirm that the lead level is truly elevated. 

The other screening method currently used is a venous blood test, or the testing of blood taken from a child s vein. Some practices use the venous test on a regular basis to avoid having the false positives from finger stick tests and the need to retest. Finger sticks might be used, for example, only when a child will not sit still for the venous test. 

In practical tests, the threshold concentrations against blue-stain and mold in a stick-test (50% ethanol solution) are ranging between 50 and 1000 ppm (Aureobasidium pullulans, Aspergillus niger, Sclerophoma entoxylina) and 1000 to 5000 ppm (Trichoderma viride). 

A synergistic effect of Bethoxazin with Preventol TP OC 3061 was observed in the poison plate test with Aureobasidium pullulans, Aspergillus niger, Sclerophoma entoxylina and Trichoderma viride and in a stick test (Scots pine) with Aureobasidium pullulans, Aspergillus niger, Sclerophoma entoxylina and Penicillium purpurogenum (De Witte et al., 1999).
