Series TT01 Cap Torque Testers are designed to measure the application and removal torque of bottle caps. Step 1 – Insert Breakaway Torque Tool into Bearing Insert breakaway torque tool into bore of the bearing until the flange sits flush against the bearing. The tester features three measurement modes: TR, PP and PD. kebamerica.com. That means the tool … With our clamps, breakaway torque is determined in the development phase in order to ensure that sufficient clamping force – in addition to all existing requirements – is maintained. This breakaway point is detected as an initial peak, and is followed by a reducing running torque. but if requirement falls outside of limits a tool can be made to suit. It is similar to the “ first movement ” method, with one basic difference. The greater the friction, the greater breakaway torque required. DI-12 Automatic Breakaway Torque Tester drives the test piece at consistent speed and detects breakaway torque without overtorquing … The IMADA DI-12 automates this complex operation. What is breakaway torque or as others call it, Residual Torque? The DI-12 outputs torque data continuously (in PD mode) to data acquisition software via the USB virtual COM port, enabling the display of breakaway torque profiles. The tip cap is held in a positive-fitting fixture with toothed pulley and belt. The breakaway is the preferred method for the measurement of residual torque. Once breakaway torque is measured, power drivers can be reset to the proper tightening torque. Breakaway Torque Tester DI-12 Breakaway Torque Tester DI-12 breakaway torque tester verifies the actual tightened torque of a fastener. ISO-17025 Certificates are available at an additional charge. As a result, “applied torque” does not equate to “actual tightening torque.“ For this reason, auditing the actual tightening torque is critical. The bearing preload is determined by measuring the torque required to rotate the inner race while the outer race is held. Power tools provide dynamic torque that can vary depending on many variables, such as joint material types, joint layer thicknesses, temperature, the presence of lubricants, etc. Part of testing the fastener includes measuring the … Warranty Return Privacy Repair/Calibration, IMADA, Incorporated
Other sizes are available with special order. This process involves applying additional torque to a tightened fastener to detect actual tightened torque as the fastener starts moving. Controlling the tightening torque on fasteners (bolts and screws) being tightened by impact and non-impact power tools is challenging. PNote Calculation results of the test self-locking torque statistical control methods pnooesu (SPC) has no statistical significance a Clamping force nuts for strength class 04 is equal to 80% of the test load for nuts strength class 04 nominal diameter of 3 mm . Gsv�^}���l.��J�C����W��)�pi͔xO,����'��u�[�+����e{5KT� �`�$���Ch�+�x[�҅�۔&ܲ����wwx_L�`k}��c��@�3&d�a�9�&�Ŝ��a��T�e�eڞ Breakaway Torque — The torque necessary to start relative ro-tation between a locking fastener and its mating thread with no axial load on the screw. q�R�. Additionally, performing a good breakaway test requires a skilled operator and many hours of training and experience. A rugged aluminum design and simple, intuitive operation allow for use in laboratory and production environments. Mechanics and engineers often measure the breakaway torque of threaded fasteners in part to ensure product integrity as part of a process called torque auditing. We do this in relaxation tests, for example. The most common torque auditing method is breakaway testing. Virtual RS-232 (9600 bps): PP 1 peak data, PD 80 data/sec. This will change with reuse and be referred to as the “1st Off”, “5th Off” torque and so forth. All testers are sold in a complete kit with tester, hard plastic carrying case, and AC adapter/charger.The DI-12 can run on internal rechargeable batteries or the AC adapter/charger. The larger impact wrench method would be done by using the more powerful tool to tighten a nut/bolt over the maximum torque which the impact being tested could achieve on it’s own (for example — 1,100 ft-lbs). The DI-12 can also detect yield torque value for a specific joint, to easily establish ideal tightening torque. Imada’s DI-12 motorized auto-detect breakaway torque tester drives the test piece at consistent speed and detects breakaway torque of even small or plastic fasteners. Once torque has been applied to a joint, an audit function measures exactly how tight that fastener was torqued. Spillage on filling can either … Emperor TM Torque software: Unlimited capability for all closure torque tests. All testers come with a 3-Point Certificate traceable to NIST. These wrenches feature a large easy to read dial with an indicator needle to record the highest torque before the breakaway occurs. Torque is applied to tip caps on disposable medical syringes to determine their breakaway torque. The tester would then take the lesser-powered impact and would immediately try … Using an Imada DI-12 motorized auto-detect breakaway torque tester, operators achieve a more reliable and consistent breakaway torque measurement, even in the case of small or plastic fasteners. Perform Breakaway Torque Test On main screen, click U/S button to select between units: cN-m, in-lb or kg-cm. The new torque tester had to be able to test tamper-evident closures for breakaway (or slip) torque and bridge torque on a wide range of plastic and glass bottles and pots. breakaway (slip) torque . Instead of applying torque in the tightening direction of the fastener, this test uses force in the direction that loosens the fastener. After being tightened, and torque is applied, there is a point when the fastener begins to move again. The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. This test method is to be used to measure the locking torque, breakaway torque, torque off and preload of threaded collars. The Imada Cedar DI-12-SL Automatic Breakaway Torque Tester is designed to find the actual yield tightening torque value for specific thread joints which consist of a variety of thread types, multi-layered material, hole sizes, etc.Torque controlled power tools are set to apply consistent torque, but fasteners are not necessarily tightened to that value if the tools are not calibrated. %PDF-1.5

The friction may be between the container finish or seal and the cap or its liner, in the screw thread or threads, or all of these. On this basis, we recommend the tightening torque and tightening speed that must be complied with to our customers. DI-12 Breakaway Torque Tester. *�����oZN?���(w�h�p��/ However, auditing fasteners made of plastic or small-size screws is often challenging, as standard breakaway testing will not always show a clear dip in torque. The DI-12 also can be used to detect the yield torque value of a specific joint, to help establish an ideal tightening torque value by testing—not by commonly used calculation methods. PD determines breakway and yield torque (CW only). Typical, standard tools work within a range 5-170in/lbs. 3100 Dundee Rd., Suite 707, Northbrook, IL 60062 © Copyright 2021ISO 9001 Registered & ISO/IEC 17025 Accredited Phone: 847-562-0834 Fax: 847-562-0839, ISO 9001 Registered & ISO/IEC 17025 Accredited.

�bu5j��[����e�%���&. The Importance of Torque Auditing 2 Normative references. This test is also known as the “breakaway” test. If the breakaway force of a nut is too low, the vibration of the equipment may cause the nut to loosen; if it's too high, the threads may strip and the bolt may be impossible to remove. Aero Staking Break Away Torque testers and receiver cups are made-to-order devices that are designed to help measure effectiveness against the requirements of the customer specification. Plain Bearing No-Load Rotational Breakaway Torque Measurement ARP5448/5 This test method provides a procedure for measuring no-load rotational breakaway torque of self-lubricating spherical bearings. In order to test the light breakaway and running torque values required to operate the dosage dial, it is essential to eliminate friction and position the sample with absolute concentricity. TR displays real time torque values. Test fixture for tip cap breakaway torque with a single-axis testing machine Torque is applied to tip caps on disposable medical syringes to determine their breakaway torque. There are two basic types of torque-to-turn tests: Breakaway torque (BT) is required to get the shaft moving, to overcome the inertia of the crankshaft and the static friction between it and the seal. !��,/�Lܼ�:��O�����/8܀NXD-k�*�5�p�|�dӱ����.��u.�\���+���_��2�Wˣ�M���AG wI!}�d�ِ&���]A����⍣Jafn�������2�#L�cn*w䵈�f��!
