Click to learn more. The proportion spent on preventive maintenance peaks in years when expensive actions are carried out i. Certification of persons 5016-3 recognize your skills, register online to become certified. Also, preliminary information on probable cause, including technical evaluation, could be included to enable allocation of acceptance criteria.

The Customer should document his process for choosing RAM Requirements stating the consideration given to address each requirement chosen.

Software for railway control and protection systems. We are a non-profit group that run this website to share documents. Table 3 — Example of minimum set of data representing a breakdown structure Subject Details Code Breakdown level code of the item Description Description of the item Qty Amount of the item under consideration in the higher level item Part No. However, it provides, only as an example, typical data and document templates for recording the output of a RAM analysis.

This clause gives detailed information on phases 1, 2, 4 and 5 of system life cycle requirements described in 6. Customers who bought this product also bought BS EN More information add to basket. Since configuration control applies to all project phases see EN Figure 9, Note 1when the project progresses through Phase 10 to Phases 11 501126-3 beyond, a suitable Configuration Management System should also be established by the Customer.


Railway Customers and Operators require railway products that are reliable, safe and can be easily maintained over their useful lives. 50126- main characteristics and features necessary to describe a rolling stock are its Mission Profile, Route Profile, Operating Conditions, Environmental Conditions and Maintenance Conditions including logistics.

The aim of this section is to provide simple guide line to help Customers choose appropriate figures for RAM requirements. In any case the total costs incurring during the main phases can be grouped under the following three categories: Generally, the depth of analyses is limited to the level of Breakdown Structure for which, data and specification of the technical and functional design is available in sufficient detail.

Compatibility between rolling stock and train detection systems. It defines a comprehensive set of tasks for the different phases of a generic life eb for a total rail system.

Considering the deliverables of the previous sections of the Guide the Customer should: Code s Theme s As these actions are only carried out two to five times throughout the 5026-3 life, consideration should be given to these when preventive maintenance costs are evaluated.

Union and other countries. Solutions used should, to the maximum extent, make it possible to interchange parts with others already in use by the customer and installed on other rolling stock.

The completion of a suitable model is outside the scope of this guide but the above information is useful to give an overview and to better introduce the RAM parameters for inclusion into an LCC model. Following this simple outline, the derivation of detailed sub-categories and costs can be easily carried out and so it makes modelling of LCC possible.

After receiving offers the Customer evaluates the docum ents and chooses the best offer.


This technical report is based on EN – 3. In designing equipment every opportunity should be applied to increase the modularity of the object so as to reduce intervention time, the specialisation of the personnel required and the stocks to be kept on hand.


For parts already in use by the customer, he should supply a list. Although some of 5016-3 examples given in the annexes of EN are for rolling stock, the standard is essentially a imed as a top level railway system document.

This breakdown is sometimes called the logistic breakdown structure. Carpeting and wall-to-wall textile flooring should be designed for easy replacement for cleaning off the rolling stock by providing appropriate breaks especially in the environments subject to heavy traffic corridors, vestibules, etc.

PD CLC/TR – September

Option to visualize changes at a glance. Follow up of critical items! There are several methods and tools to set up a breakdown structure. Thirdly, this research provides the method that develops RAMS The specification and demonstration of reliability, availability, maintainability and safety RAMS.

Also, the LCC technique can be used to give a value to compare different offers and alternatives and to control the project. During this phase the Main Supplier should also collect detailed analyses carried out by sub contractors in order to: Before responding to the call for tender, the Main Supplier has to perform relevant tasks, given below, to ensure that all risks related to the compliance with each requirement have been taken into 50126-33 The following are recommendations to be followed in order to develop 501126-3 appropriate and suitable breakdown structure for RAM purposes:
