ISO 4302:2016 pdf free download.Cranes Wind load assessment Appareils de levage a charge suspen due — Evaluation des charges dues au vent. This ISO 4302 specifies the assessment of wind loads on cranes. It establishes general methods for calculating wind loads (for in-service and out-of-service conditions), which are included in the load combinations stated in Iso 8686-1 and used for proofs of competence such as those given in ISO 20332 for the structural components of cranes. It provides a simplified method of calculation and assumes that — the wind may blow horizontally from any direction, — the wind blows at a constant speed, — there is a static reaction to the wind load applied to the crane structure. It includes built-in allowances for the effects of gusting (fluctuation in wind speed) and for dynamic response. It gives guidance on when to secure the crane for out-of-service conditions. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

It recommends the use of a linear intercept technique for obtaining data on feature sizes. The measurements are to be made using good practice for the preparation of suitable microstructures for examination outlined in ISO 4499-1. Methods of metallographic preparation and etching techniques are as important as the phase size measurement method (see also ASTM B 657, ASTM B 665, Reference [11 and Reference [21). Basic methods are described in ISO 4499-1. Further relevant information is given in Clause 8. The principal types of hardmetal considered are those that contain cubic carbides as well as WC and those that are based on TiC or Ti(C,N).[31[4][5i A cubic carbide phase is defined as a carbide having a cubic lattice,…
