A look behind the scenes
Dealing with incorrect CIP data
The company Triebel Waffenwerkzeuge has been a competent partner for many decades when it comes to cartridge bearing gauges and their technical design.
In principle, the specifications of the Permanent International Commission for the Testing of Small Arms, or C.I.P. for short, are authoritative.
Unfortunately, it has also been known for many years that the data published by the C.I.P. are often incorrect.
However, due to the complex and ponderous structures of C.I.P., reliable correction of such errors in a reasonable time has rarely been possible.
As a partner of industry and trade, with corresponding competence in the field of cartridge and stock dimensions, the company Triebel Waffenwerkzeuge has in the past always pointed out such errors in the official channels and, for the good of the industry, offered to assist in correcting them. However, a structural solution to the basic organizational problems of the C.I.P., with the aim of providing the industry with reliable and usable data, has failed to materialize to date.
However, since our customers are urgently in need of an exact and practical design of cartridge bearing gauges, the original caliber data of the C.I.P. are always extensively checked, mathematically adjusted and, if necessary, corrected accordingly at Triebel Waffenwerkzeuge, and the dimensions are extended by the number of decimal places necessary for professional gauge production.
This elaborate work is the basis for an in-house caliber database that is probably unique in the world in terms of quality and scope.
The logical consequence of the data corrections is that certain nominal dimensions of individual Triebel gauges deliberately deviate from the C.I.P. specifications. This results accordingly from compliance with the exactly calculated dimensions after data correction.
For the purpose of tracing the data, gauges affected by this will be marked with the status "CIP+" by laser engraving and in the associated measurement report from the beginning of 2023. CIP+ means that the so-called basic dimensions of the C.I.P dimension sheets are adhered to, but the dimensions derived from them may deviate.
For professional gauge management and dimensional control of cartridge bearing gauges, it is therefore advisable to always adopt the nominal values from the measurement record of the factory test. This avoids misunderstandings and ensures that the corresponding gauge is suitable for the intended test application.
In individual cases, you can receive information on a specific gauge by email upon request. Please contact us via info@triebel-guntools.de, if possible stating the article and serial numbers of the respective gauges.
