om CE-märkning..
Så som jag förstått saken är CE-märkning endast en för EU godkännd beteckning rörande miljö och säkerhet - runt produktionen, inte beträffande produkten själv. Typ som att köpa ekologisk mjölk.
Däremot så finns det ju UIAA-märkning på en del grejor. Dessa ska ha testats i enlighet med UIAAs krav av UIAA godkännda testlaboratiorier.
Märken godkännda av UIAA ska finnas på deras hemsida.
Jag letade lite på deras hemsida och fann en del intresseväckande material. Här beskrivs hur de testar en karbin.
----------------------------
"2.2.4. Test device
The test apparatus consists of a vertical steel pin of diameter (16 + 0.1) mm, rigidly mounted abave a thick, horizontal steel plate- The horizontal plate has an edge of radius (2 + 0.1) mm. The distance between the edge and the vertical axis of the pin is (27 + 0.1) mm. /…/
2.2.4.2. Test method
Clip the larger end of the test sample onto the vertical pin, allowing the autolocking gate to close and lock. Arrange the connector so that its smaller end overhangs the horizontal edge. If the connector is not supplied by the manufacturer with a rope or tape attachment, make suck an attachment in accordance with the manufacturers´ instructions. Apply a force vertically downwards to the small end of the connector by loading the rope or tape attachment. Apply the force at a speed of 20 to 200 mm/minute. Increase the force to 8 kN and check that the connector has not become detached from the vertical pin. Permanent deformation or fracture of parts of the connector is acceptable. "

"Connector cross-sectional profile and thickness
Neither the cross-sectional profile and thickness, nor the curvature of the connector surface in the region that comes in contact with the rope under load are specified in the UIAA 121 or EN 12275."

I beskrivning av hur tex. dynamiska rep testas hittade jag ingenting om hur det går till. Om tester över dynaiska rep med särskild hållbarhet mot slitage över skarpa kanter fann jag följande:
----------------------------
"During routine testing to the UIAA Safety Standard 108 Sharp Edge Resistant Dynamic Ropes, at the UIAA-approved test laboratories, discrepancies were found in test results for the same rope at different laboratories. Until this problem is resolved, the testing of ropes against this safety standard has been suspended at all test laboratories as from 1st July 2004. Models of rope already certified “Sharp Edge Resistant” will retain that status until 31st December 2005. This standard is available at the moment for information in relation to rope models already certified. Work is in hand to resolve the above problem, and any revision to the standard will be published when available."

----------------------------
"3.3 In sections 3.1 (a) and 3.2 (a), every test shall be carried out on three items of production, and every item of production shall pass the test(s)."
----------------------------
Detta tolkade jag som att all utrustning inte är individuellt testad att hålla det uppsatta kravet på motstånd.
