TRANSCRIPT
Rivet testerThe patented rivet and tool test
both for blind rivet and rivet gun as well as rivet nut and setting tool
The rivet tester by CSP provides you with reliable information for A-classified joints and thereby more safety for your products
This applies both to analyses in the lab (e.g. material tests) and tests in assembly and for maintenance (e.g. after repairs).
You may also generate your own data for rivets which reflect your application scenario more precisely than general
manufacturer specifications.
Control measurements thus improve your rivet joints and tools:
To test the rivet units, the rivet unit and blind rivet (rivet
nut) is used with a material strip (e.g. sheet metal) that
is identical or similar to the original component with
regard to composition and thickness.
The material strip is fitted with rivets or rivet nuts and
inserted into a clip.
The loaded clip is placed into the measurement cell.
Both the rivet gun and the entire riveting process are
thus tested and riveting force and path are measured.
Apart from the quality assessment of the tool, conclusions as to the rivet joint on the product are also possible.
How? With the help of the rivet tester, the capability of the tool used (machine capability testing) and the behavior in the
process can be simulated and substantiated. Management and documentation of the data takes place, as already tried
and trusted in screwing technology, with our standard software QS-Torque. Your test data is recorded in QS-Torque and
compared by way of illustration for easier reporting.

Quick, secure and traceable control measurementof rivet tools with the rivet tester by CSP
Rivets become increasingly important in modern assembly. Consistent quality assurance is therefore especially
important.
For the first time, the rivet tester by CSP tests your riveted joints and riveting tools in functional context and automatically
documents the results. By recording and comparing the force-path traces of rivet and test devices, you can perform an
exact analysis of your rivet processes at any time.
This optimizes your processes, increases your quality and lowers your costs!
According to VDI/VDE 2862, risk
assessments for fasteners in assembly are
divided into categories A (safety-relevant),
B (function-relevant) and C (customer-
critical).
For category A, high requirements within
the legally stipulated product liability apply
with regard to the tools employed and the
products fabricated with them. Presenting
proof of the tool and product capability
with corresponding documentation is
inevitable.

Tool and product test in a single stage
Thanks to the possible merging of original parts from assembly batches (rivet or rivet nut) with sheet metal strips identical
to the components and the assembly tools used, a combination of tool test (MFU) or random sample of the device and
process test (PFU) of the fastener with the material (part) is created.
One or several material strips, also of different quality and thickness, can be used for the test. The key factor is that the
difference to the original assembly process is as small as possible. This produces much more useful and realistic measuring
results as, e.g., screwdriver tests where no use of components or fasteners is possible in simulation.

Your benefi ts at a glance
QUALITY
The rivet tester by CSP increases the quality of your products since it reliably tests your tools (rivet guns and rivet setting devices) as well as rivet joints.
CONTROL MEASUREMENTS AND ANALYSES
Traceable and documented control measurements and analyses of your rivet tools allow you to intervene more quickly in case of defects. This saves unnecessary costs, for example,for rework and product recalls.
SAFETY
The use of the rivet tester enables you to increase the quality of safety-critical joints.
MANUFACTURER INDEPENDENCE
You may employ the rivet tester individually since it tests rivets and tools regardlessof the manufacturer.
