There has been some controversy over information on an Italian website.   Here is Petzl’s offiicial response:.

 

Following the recent publication of 2013 CROLL tests on an Italian website (http://www.sns-cai.it/item/test-sul-crol-petzl-di-recente-produzione), Petzl would like to remind users of the following facts:

·  The new 2013 CROLL complies with the requirements of the EN567 standard when used with authorized ropes types (8-11mm). The CROLL withstands 5 consecutive static pulls of 4kN. During these tests the clamp was never pulled out.

·  We have tested the new 2013 CROLL with a large selection of ropes in slow pull static testing. The forces at which the sheath of the rope tore were: 5kN for the 8mm, 6-7 kN on the other diameters.

·  During product development and production, we have conducted many dynamic tests (shock load with a  rigid mass near an anchor point and extreme destructive tests with a guided mass on worn out ropes of large diameter) — in these tests the clamp was never pulled out and the sheath of the rope was torn.

·  In normal use, the CROLL should never encounter such high forces, but it is critical that this (and all Petzl PPE) be used in accordance with the technical notice : http://www.petzl.com/files/all/technical-notice/Sport/B16-CROLL.pdf

·  Petzl will contact the authors of these tests as soon as possible to exchange information.
