Tests such as Rotter Impact, Ball and Disc and Friction Pendulum [1-41 examine the level of mechanical stimuli required to cause 50% probability of ignition. An illustration of the Rotter Impact test to determine Figure of Insensitiveness is shown in Figure 1. Sensitivity tests are .

More recently, Mullenger derived a new experimental Rotter method utilizing gas .A total of nine impact tests were analysed and their characteristics have been compared, with a particular focus on the most commonly used tests (BAM impact, Rotter impact, and ERL type .

Shock sensitivity is a comparative measure of the sensitivity to sudden compression (by impact or blast) of an explosive chemical compound. Determination of the shock sensitivity of a material intended for practical use is one important aspect of safety testing of explosives. A variety of tests and indices are in use, of which one of the more common is the Rotter Impact Test with results expressed as FoI (Figure of Insensitivity.) At least four other impact tests are in common use, w. The impact sensitiveness of an energetic material is assessed using the rotter impact test with a higher value denoting a lower chance of detonation due to impact (United .More recently, Mullenger derived a new experimental Rotter method utilizing gas volumes evolved under impact to measure explosiveness of energetic materials [29]. This has now .The explosive characteristics investigated included the Held criterion, the weight percentage of RDX, the composition density, the composition, the Gurney energy, the Rotter impact test .

Quantitative measurements o f the enhanced sensitiveness, made by means of the Rotter impact machine, have included tests on the high explosives: T. N. T., picric acid, tetryl, cyelonite and .Rotter test. It remains to be determined whether this apparatus will replace the mallet/anvil test or prove to be more informative than the Koenen friction machine mentioned earlier. . The United Nations lists six tests to analyze the impact sensitivity of explosives, 11 with the three most common being the BAM Fallhammer test, 12, 13 the US drophammer .

Impact is also a leading manufacturer of test sieves within the UK, Impact has been supplying to engineering, mining, chemical, pharmaceutical, agricultural and food industries for over 20 years, and are proud to have a reputation for supplying quality products and excellent service.We have conducted studies investigating laboratory test characteristics correlations [2], including the NEWGATES gap test data. The explosive characteristics investigated included the Held criterion, the weight percentage of RDX, the composition density, the composition, the Gurney energy, the Rotter impact test and the detonation state properties. The Rotter impact test was conducted in accordance with EMTAP test guidelines (Citation 2007) and the UN Transport of Dangerous Goods Manual of Tests and Criteria (Citation 2011). A 5 kg weight was dropped on 55 individual 30 mm 3 samples. A go/no go response for initiation was recorded and the height of the drop weight was increased or lowered . Impact of Julian Rotter’s Locus of Control on Behavior ‘Julian Rotter locus of control’ has wide-ranging implications for different fields of human study. People with an ‘internal locus of control’ usually demonstrate a higher level of initiative, endurance, and tenacity as they believe they are the masters of their destiny.

The sensitiveness of explosives

The impact sensitiveness of an energetic material is assessed using the rotter impact test with a higher value denoting a lower chance of detonation due to impact (United Nations, 2009). It is these similarities, along with the increased figures of insensitivity over their predecessors, .3.1 Impact Sensitiveness 3.1.1 MRL Test Method: Rotter Impact Sensitiveness (5a. 6] Impact sensitiveness was determined on a Rotter apparatus. The sample of about 30 mg confined in a brass cap fitted over a polished steel anvil was impacted by a 5 kg weight falling from a preset height. Go/no-go Rotter impact test data indicate that the cyclic nitroguanidines 1–4 are more easy to initiate than RDX; however, the extent of propagation is less and depends on oxygen balance. Consideration of Hazard Index and Average Powder Explosiveness data indicates that US drop-weight tests, which measure a combination of ease of initiation and extent .

Main impact machine types are BAM Fallhammer (by Bundesanstalt für Materialforschung, now most widely used, especially in Europe) [7], ERL type 12 Drop Weight Sensitivity Apparatus (developed and still in use in USA) [8], UK Rotter test (still used in industry in Great Britain) [9], and K-44–2 impact machines (by former Kuibyshev Polytechnic . Rotter impact test data indicate that the cyclic nitroguanidines 1–4 are more easy to initiate than RDX; however, the extent of propagation is less and depends on oxygen balance.

understood. Barmonisation of the test method on the international level has shown up difficulties which are discussed later. b) Steel box test22, in this test the sample is held in a 8cm cubed steel box with a crimped-on lid, and is heated with either gas burners or a wooden crib. The procedure is described in ADR/RID and specifies crib timber ofThe impact and friction sensitiveness were determined using Rotter Impact Test and BAM friction tests. The results of these tests together with ESD test results are provided in Table 2. The impact sensitivity of DNAN in both the pure form (and with grit added) is very low (F of I >220).3 The impact sensitivity of ARX-

Taylor & Weale’s test. This suggests that compounds which undergo a marked increase in sensitiveness on changing from this test to the Rotter test are specially liable to the element of rubbing or pinching, which the Rotter test includes to a much greater degree. In order to obtain a more fundamental measure of the influence of impact and .

The Rotter impact test was conducted in accordance with EMTAP test guidelines (2007) and the UN Transport of Dangerous Goods Manual of Tests and Criteria (2011). A 5 kg weight was dropped on 55 individual 30 mm3 samples. A go/no go response for initiation was recorded and the height of the drop weight was increased or lowered depending on the .A Review of the Mallet Impact Test for Small Scale Explosive Formulations Matthew Weaver, Lisa H. Blair, Nathan Flood and Christopher Stennett. . In the Rotter test the explosive is placed in a brass cap which is then placed on the anvil and housing. The sample is spread evenly over the pip surface by rotating the cap on the anvil.Do you have an internal or an external locus of control? Are you in charge of your own destiny?

Rotter (1916 - 2014) Biographical Note. Julian B. Rotter was born in October 1916 in Brooklyn, NY, the third son of Jewish immigrant parents. Rotter's father ran a successful business until the Great Depression. The Depression powerfully influenced Rotter to be aware of social injustice and the effects of the situational environment .I was blown away with their application and translation of behavioral science into practice. They took a very complex ecosystem and created a series of interventions using an innovative mix of the latest research and creative client co-creation.Finally, the Gurney energy, the Figure of Insensitiveness of the Rotter Impact test and the detonation performances do not present any relationship with the critical diameter. To expand this work, more experiment should be realized and more importantly an international standard should be provided to harmonize the determination of the critical .

The Rotter Incomplete Sentences Blank is a projective psychological test designed to evaluate an individual’s attitudes, concerns, and emotional patterns.
