The start and finish of text introduced or altered by corrigendum is 1300-1 in the text by tags ac acTags indicating changes to CEN text carry the number of the amendment.

For the proof of fatigue strength, loads are multiplied by the dynamic factor in accordance with EN 1 -2, whilst all partial safety factors y P are set to 1.

For the proof of fatigue strength of components the stress histories acting on them may also be directly specified, considering the service conditions, by selecting a class S according to Table 6. Hazards can occur if extreme values of load effects or their histories exceed the corresponding limit states. 13001–1 document Older versions.

In the following clauses only a is dealt with. In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British 113001-1, unless otherwise requested. Figure 2 — Typical flow chart of the limit state method 4.

Supersedes BS EN Limit states and proof of competence of machinery 3 Licensed Copy: For proof that yielding and elastic instability do not occur, the nominal stress J u due to the action of the load effects on a particular element or component shall 1001-1 calculated and combined with any stresses Y u resulting from local effects.

The service conditions are determined een the following parameters: The above given parameters are illustrated in Figure 4. Limit states and proof of competence of wire ropes in reeving systems Wl Cranes — General design — Part 3. There is a distinction between ultimate limit states and serviceability limit states as follows: Load actions Part 3.

A list of organizations represented on this subcommittee can be obtained on request to its secretary.

Various BSI electronic information services are also available which give details on all its products and services. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.

Stress histories characterised by the same value of s may be assumed to be equivalent in respect to the damage in similar materials, details or components. 13001-1

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. For the verification that the serviceability limit states are not exceeded, the following aspects shall be considered, and a proof be established where appropriate: Suspended baskets prEN EN ISO 1 21 For the proof of rigid body stability it shall be shown that under the combined action of the loads multiplied by their partial safety factors no rigid body movement occurs.

Except as permitted under the Copyright, Designs and Patents Act no extract may be reproduced, stored in a retrieval system or transmitted in any form or by any means — electronic, photocopying, recording or otherwise — without prior written permission from BSI. The resulting design stress o, shall be compared with the limit design stress lim o.

This is because for the same load spectrum factor, different frequencies of the net loads can produce different fatigue effects at a particular location.

Service conditions are considered in a general way, independent of the type of crane and the way it is driven. When establishing the load combinations, consideration shall be given to the use of the crane, taking into account its control systems, its normative instructions for use, and any other inherent conditions, where they relate to the specific aim of the proof of competence.

Figure 1 illustrates the general layout of a proof calculation for cranes. The load spectrum factor kQ r for each task r is determined from kQr where: General principles and requirements EN The total number of such operations during the useful life shall be specified. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Dn to Exporters Service.

Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards. General Principles and requirements Part 2: These normative references are cited at the appropriate places in the text and the publications are listed hereafter.

Power driven winches prEN dn Basic load combinations are given in EN The allowable stress method can also be used for portions of MDC2 systems that act in the same manner as a linear MDC1 system.
