Corrosion testing atmospheres conducive corrosion. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

BS EN ISO 16047:2005+A1:2012

We have capability to collect time synchronized data across multiple instruments and sensors including the following:. Need more than one copy? 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. Uncoated reference parts are oiled to protect against corrosion and later cleaned again.

Electrostatic powder spraying EPS. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of oso to or new editions of the standards required in your work. For example, brighteners in the galvanised coat serve to lower the friction between reference part and fastener. Tightening specifications for normal fasteners are also applied for those with washers.

The variety around the topic of corrosion and corrosion protection is also in our glossary at home: This technique has a distinct advantage because the actual joint and fastener can be tested without compromising the joint stiffness through the introduction of a load cell. If the factor is very high, fasteners need to be tightened with a high torque and the efficiency of the fasteners decreases.


As a result, the coefficients of friction calculated from torque and clamp force only really apply to the conditions on the test bench.

Your Alert Profile lists the documents that will be monitored. The ISO standard describes reproducible laboratory tests. Surfaces often have a major influence on this.

Virtual Validation FEA can give virtual insight into the structural integrity of new designs before any capital is spent building parts. Coefficients of friction cannot be specified using measurement technology. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. However, specialists also take a closer look.

Not only can FEA show where new parts may have potential issues, it can be used to diagnose failures seen in the field, and also to optimize designs in order to reduce cost.

We have no amendments or corrections for this standard. For hard bases the is prescribes a narrow range of hardness, but permits a broad range of hardness for soft bases. Instructions for resetting the password will uso immediately emailed to you.


They are identified via torque and clamp force. The friction between roughened surfaces is greater than between smooth ones. FEA can give virtual insight into the structural integrity of new designs before any capital is spent building parts.

Product Validation, Verification and Testing

In order to achieve the desired clamp force with a specified torque, the tightening instructions must assume a total coefficient of friction of the fasteners. The objective is to fix components to each other in a way that enables them to fulfil their function.

Eddy current method phase sensitive. With these tests it is also possible to check the quality of the coating in ongoing production. When tightening the bolt the clamp force, the rotation angle, the total torque and one of the two partial torques are measured.

Every day, thousands upon thousands of screws and bolts are used to fasten components together. 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. A bolt that requires 160477 is screwed into the test bench and fixed with a reference bolt. Some of the capabilities at Matrix Engineering Consultants include:
