according to test requirements such as BS Pt. 2 or ISO This can be expressed in two ways, the Coefficient of Friction µ and the Torque Coefficient (K . ISO FASTENERS – TORQUE/CLAMP FORCE TESTING. DIN EN ISO Fasteners – Torque/clamp force testing (ISO + Amd ) (includes Amendment).

Please enter your username or email address. Similarly, varying degrees of roughness are possible for both types. Such data can be used to establish the appropriate torque-angle requirement for the specific fastener and joint.

In this it is jso necessary to take into consideration the geometry of the fasteners — more precisely, the increase of the thread, its flank diameter and isso diameter of the head contact. That may sound routine initially. Pressure water jetting test.

Electrostatic powder spraying EPS. The benefits of a subscription: The variety around the topic of corrosion and corrosion protection is also in our glossary at home: However, specialists also take a closer look.

In order to achieve the desired clamp force with a specified torque, the isl instructions must assume a total coefficient of friction of the fasteners.

Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Industrial companies and associations often specify 61047 coefficient of friction window for this.

This standard sio also available to be included in Standards Subscriptions. Standards Subsctiption may be the perfect solution. Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. We have no document history for this standard.

FEA can give virtual insight into the structural integrity of new designs before any capital is spent building parts. This will give you increased confidence in your fastener designs and manufacturing processes.

ISO – Fasteners — Torque/clamp force testing

When tightening the bolt the clamp force, the rotation angle, the total torque and one of the two partial torques are measured. Corrosion testing atmospheres conducive corrosion. In this process the fasteners are screwed to their own washer. The bolt heads lie on a reference base plate or a reference washer.

MEC can be perform tests on actual fastened assemblies to obtain torque-angle graphs and to establish the torque to reach the yield strength of the bolt. Torque to Yield Tests MEC can be perform tests on actual fastened assemblies to obtain torque-angle graphs and to establish the torque to reach the yield strength of the bolt. Eddy current method amplitude sensitive. Some of the capabilities at Matrix Engineering Consultants include: With these tests it is also possible to check the quality of the coating in ongoing production.

If the factor is very high, fasteners need to be tightened with a high torque and the efficiency of the fasteners decreases. As the voice of the U.

Instructions for resetting the password will be immediately emailed to you. The friction between roughened surfaces is greater than between smooth ones. In cases where fluid flow is critical either gas or liquid CFD can be used to optimize flow and minimize turbulence, or to predict how two different liquids are mixing, etc.

Eddy current method phase sensitive. Uncoated reference parts are oiled to protect against corrosion and later cleaned again.

It can also be used in conjunction with FEA when a transfer of fluid causes a resultant force that needs to be considered when doing structural analysis. There are many types of engineering simulation and 116047 that Matrix Engineering Consultants performs either as a stand-alone isi or integrated into our projects. If fasteners are lubricated, friction is reduced — this applies both with regard to both external lubrication via grease or wax and integrated lubrication via the addition of a lubricant to the coating.

If they are fastened too tightly, components and the fasteners themselves may be damaged.
