It covers requirements for metallic materials as well. | Head of the Corrosion, Arab Petroleum Pipelines, By: Greg Denton The 50 kN capacity and the fully variable test speed of 0.2 to 51 mm/min make it possible to perform not only the CBR and Marshall tests, but many other applications as for instance Indirect Tensile test, Quick Triaxial tests, Unconfined and Uniaxial soil testing and, in general, all test to be performed under displacement control. This is also in part due to the fact that the values do not relate accurately to the impact strength of moulded parts or actual components under actual operational conditions. .essb_links_list li.essb_totalcount_item .essb_t_l_big .essb_t_nb:after, .essb_links_list li.essb_totalcount_item .essb_t_r_big .essb_t_nb:after { color: #777777;content: "shares";display: block;font-size: 11px;font-weight: normal;text-align: center;text-transform: uppercase;margin-top: -5px; } .essb_links_list li.essb_totalcount_item .essb_t_l_big, .essb_links_list li.essb_totalcount_item .essb_t_r_big { text-align: center; } .essb_displayed_sidebar .essb_links_list li.essb_totalcount_item .essb_t_l_big .essb_t_nb:after, .essb_displayed_sidebar .essb_links_list li.essb_totalcount_item .essb_t_r_big .essb_t_nb:after { margin-top: 0px; } .essb_displayed_sidebar_right .essb_links_list li.essb_totalcount_item .essb_t_l_big .essb_t_nb:after, .essb_displayed_sidebar_right .essb_links_list li.essb_totalcount_item .essb_t_r_big .essb_t_nb:after { margin-top: 0px; } .essb_totalcount_item_before, .essb_totalcount_item_after { display: block !important; } .essb_totalcount_item_before .essb_totalcount, .essb_totalcount_item_after .essb_totalcount { border: 0px !important; } .essb_counter_insidebeforename { margin-right: 5px; font-weight: bold; } .essb_width_columns_1 li { width: 100%; } .essb_width_columns_1 li a { width: 92%; } .essb_width_columns_2 li { width: 49%; } .essb_width_columns_2 li a { width: 86%; } .essb_width_columns_3 li { width: 32%; } .essb_width_columns_3 li a { width: 80%; } .essb_width_columns_4 li { width: 24%; } .essb_width_columns_4 li a { width: 70%; } .essb_width_columns_5 li { width: 19.5%; } .essb_width_columns_5 li a { width: 60%; } .essb_links li.essb_totalcount_item_before, .essb_width_columns_1 li.essb_totalcount_item_after { width: 100%; text-align: left; } .essb_network_align_center a { text-align: center; } .essb_network_align_right .essb_network_name { float: right;} Subscribe to our newsletter to get expert advice and top insights on corrosion science, mitigation and prevention. Discussion : 1. This test can be used as a quick and easy quality control check to determine if a material meets specific impact properties or to compare materials for general toughness. The direct hardness number is read out on the dial. Most, if not all of us, have a hobby. Also comes with an option to connect to a PC for advanced software analysis. Where Does The Texas Colorado River Start, Brittle materials generally have lower impact stregths, while those registering higher impact strengths tend to to be tougher. Technical Teaching Equipment. It is especially suited for testing harder materials such as shoe soles, tires and other rubber materials. At Applied Technical Services (ATS) our experts provide helium leak detection services for companies in various industries. The size of the samples also has a great impact on the test results hence it is essential to choose standard sizes of the specimen. This setup offers less protection.
