Instead Of Earning A Small Fee On A Building Project, A Materials Testing Laboratory Can Instead Become Involved In Litigation Which Could Cost It And Its Liability Insurers An Amount Many Times The Fee. But More Than This, There Could Also Be An Infinitely Greater Amount Of Time Spent Defending The Firm Than Was Ever Spent In Performing The Tests. In The Majority Of Cases The Tests Are Performed To Either Supply Design Information Or Monitor Compliance With Project Specifications And/Or Building Code Requirements. However, If Problems Develop And Litigation Begins, Then The Project File Information Becomes Evidence Of What Took Place On The Project. In Some Cases, However, The Laboratory Is Employed After Litigation Has Begun, Or The Probability Of A Lawsuit Is High, And The Testing Is Performed To Provide Evidence. In Any Event, The Results Of These Tests Are Taken As Essential Facts Which Will Be Reviewed By The Attorneys And Their Forensic Engineering Experts. Sometimes The Technicians Or Managers Of The Firm Providing These Field Or Laboratory Results Will Be Deposed, And Every Raw Data Sheet, Report And Log In The File May Be Examined In Great Detail By The Various Parties. If One Error Is Found, It May Be Contended That There May Be Other Errors Which Have Not Been Found Yet. If It Develops That Any Errors Or Suspected Errors Were Made, Then The Laboratory May Become Party To The Lawsuit.

OBJECTIVE: To evaluate the marginal misfit between intermediate and micro-unitmetal cylinder, by varying the angle of the implants, using two different types of material and different molding techniques. METHODS: A model was made with three implants (one perpendicular to the horizontal plane and two inclined) using micro-unit intermediates. A rod attached to the master model served as a control condition to evaluate the suitability of the twenty specimens, carried out with the help of an optical stereomicroscope (Pantec, Brazil; Materials Testing Laboratory, São Leopoldo Mandic, Campinas, São Paulo). RESULTS: Evaluator reliability was assessed using theIntraclass Correlation Coefficient, obtaining 99.6% (excellent). There were significant differences between groups, and the Mann-Whitney test compared groups in pairs for a more accurate result. CONCLUSION: The group which presented the best behavior was open tray and condensation silicone and the worst result, that needed to be cast several times, was closed tray and condensation silicone.

Explosive Properties

The article is devoted to testing samples of the emulsion explosive Senatel Magnum before and after the introduction of the marking composition for explosive properties and safety criteria. It was established that the mixture of marking substances, which was introduced into the composition of the emulsion explosive Senatel Magnum, does not affect its explosive properties, as well as its safety in use during operation and conduct of blasting operations, since no inconsistencies were detected during tests by the specialists of explosive materials testing laboratory of the Expert Certification Center of Explosive Materials LLP. Various dyes were selected as marking agents. This choice is due to the fact that the dyes have a relatively low price, are very common on sale, when mixed with other substances, in particular industrial explosives, are determined visually. The technology was tested related to the introduction of marking additives into the compositions of multicomponent explosives without disrupting the technological process of their manufacture. Laboratory and field studies were carried out concerning safety criteria for explosives containing a marking composition. Thus, the urgent task is to ensure the possibility of marking (tagging) industrial explosives at the stage of their production with hidden marking additives, which will allow the product itself to be identified with the help of technical means — as an explosive, and to establish the brand of the detected explosive, manufacturer, and other required information.
