EN 131-2-2010梯子.第2部分:要求,检验,标志

This European Standard specifies the general design features, requirements and test methods for portable ladders. It does not apply to step stools or ladders for specific professional use such as firebrigade ladders, roof ladders and mobile ladders. It does not apply to ladders used for work on or near live electrical systems or installations. ForThis purpose EN 61478 applies. NOTE For insulating ladders for use on or near low voltage electrical installations in the range below 1000 V a.c or 1500 V d.c. EN 50528 is under preparation.This European Standard is intended to be used in conjunction with EN 131-1. For single or multiple hinge joint ladders EN 131-4 applies.

DIN EN 13121-3-2016地上用GRP槽罐和容器.第3部分:设计和工艺.德文版本EN 13121-3-2016

This European standard gives Reguirements for the design, fabrication, inspection, testing and verification of GRP tanks and vessels with or without thermoplastics lining for strorage or processing of fluids, factory made or site built, non pressurised or pressurised up to 10 bar, for use above ground. The terms vessels and tanks as used in this European Standard include branches up to the point of connection to pipe work or other equipment by bolting and supports, brackets or other attachments bonded directly to the shell. In addition to the definitive requirements, this European Standard also requires the items in Clause 5 to be fully documented. This European Standard covers vessels and tanks subject to temperatures between - 40 degrees C and + 120 degrees C. It is possible that future advances in resin tecnology would allow tanks and vessels to be considered for operating temperatures above + 120 degrees C. Should such a situation arise and manufacturer wishes to take advantage of such developments, then all other requirements of the standard shall be maintained and such tanks and vessels shall only be designed in accordance with the advanced desing method given in 7.9.2 Exluded from this European Standard are:- tanks and vessels for the transport of fluids;- underground storage tanks;- spherical vessels;- vessels and tanks of irregular shape;- tanks and vessels with double containment;- tanks and vessels which are subject to the risk of explosion, or failure of which may cause an emission of radioactivity;- specification for fibre reinforced cisterns of one piece and sectional construction for the storage, above ground, of cold water (see EN 13280:2001).
