I'm looking for the following standards, concerning test methods for screed materials:
1. BS EN 13892-1:2002 Methods of test for screed materials. Sampling, making and curing specimens for test;
2. BS EN 13892-6:2002 Methods of test for screed materials. Determination of surface hardness;
3. BS EN 13892-8:2002 Methods of test for screed materials. Determination of bond strength.
I'll be very appreciate if someone who have them - share them or some of them.

Predictive and Optimised Life Cycle Management: Buildings and Infrastructure
Author: Edited by Asko Sarja | Size: 6.5 MB | Format:PDF | Publisher: Routledge | Year: 2006 | pages: 688 | ISBN: 0415353939
Predictive and Optimised Life-Cycle Management sets out methodologies to meet the demands of the current trend towards sustainable civil engineering and building.
Encompassing all aspects of construction practice, from design through to demolition and the recycling of materials, Sarja provides tools for optimal property-value protection, including a description of an integrated and predictive Life-Cycle Maintenance and Management Planning System (LMS), which employs a wide range of techniques.
Clear and practical, this guide provides effective methodology required to change a reactive system of management to a predictive one, which will benefit practitioners and students involved in construction, from the architect to local and government authorities; from design engineers to facility managers.

Adhesive bonding is increasingly regarded as a cost effective and effectual way to join mechanical structures. This book reviews recent improvements in adhesive bonding and their wide-ranging potential in structural engineering. Part one discusses methods for selecting the correct adhesive. The second set of chapters discusses the various types of adherents. A third set of chapters analyses methods and techniques for joint design. The final chapters give useful and practical insight into the problems and solutions of adhesive bonding in a variety of hostile environments such as chemical, wet, and extreme temperatures.

Cumulative damage of welded joints >> By T R Gurney, formerly TWI, UK
Author: T R Gurney, formerly TWI, UK | Size: 3.3 MB | Format:PDF | Publisher: Woodhead Publishing Limited | Year: August 2006 | pages: 457 | ISBN: ISBN 1 85573 938 0 ISBN-13: 978 1 85573 938 3
- covers the wealth of research in the field of fatigue strength and its role in the design and manufacture of welded components
- invaluable reference source for welding engineers, supervisors, inspection personnel and designers
Fatigue is a mechanism of failure which involves the formation and growth of cracks under the action of repeated stresses. Ultimately, a crack may propagate to such an extent that total fracture of the member may occur. To avoid fatigue it is essential to design the structure with inherent fatigue strength. However, fatigue strength for variable amplitude loading is not a constant material property and any calculations are necessarily built on a number of assumptions. Cumulative damage of welded joints explores the wealth of research in this important field and its implications for the design and manufacture of welded components.
After an Introduction, chapter two introduces the constant amplitude database, which contains results obtained in test conditions and which forms the basis of the basic S-N curves for various types of joint. Chapter three discusses the influence of residual stresses which can have a marked effect on fatigue behaviour. Chapter four explores variable amplitude loading and the problem of how information from laboratory tests, obtained under constant amplitude conditions, can be applied to the design of structures for service conditions. This problem is further investigated in the next chapter which is devoted to two and three level load testing. Chapters six, seven and eight look at the influence that the variety of variable loading spectra can have on fatigue strength, whether narrow or wide band loading or cycles of small stress range. Taking all of this knowledge, chapter nine discusses structure designs.
Cumulative damage of welded joints is a comprehensive source of invaluable information for welding engineers, supervisors, inspection personnel and designers. It will also be of great interest for academics working in the fields of structural and mechanical engineering.
About the author
Dr Gurney worked at TWI (formerly the British Welding Research Association) for over thirty years, during which time his primary interest was in the fatigue of welded structures. He has written or co-authored over fifty papers throughout his career.

Glass is increasingly being used as a structural material in new buildings. The structural envelope may consist either entirely or partially of glass, and this trend to eschew traditional materials such as brick and concrete for steel-framed, glass clad buildings presents inherent problems. A major issue is the performance of glazing during earthquakes and extreme climatic events, such as windstorms and heavy snow loads. This authoritative book reviews the current state-of-the art in glass and glazing technology to resist failure due to these natural events.

Press fittings are becoming more widely used in plumbing, heating and chilled water installations. BS 8537 will help manufacturers, suppliers or specifiers of copper tube fittings adapt to the increasing demand and ensure their products are suitable for use.
Specifying to BS 8537 will help manufacturers of press fittings find wider acceptance of press fittings in the UK market. Consultants often prefer to quote compliance to the standard so they remain independent from endorsing a manufacturer’s product. Pipe fittings conforming to BS 8537 are more likely to be referenced in contracts.
BS 8537 is the British Standard that specifies requirements for materials and design of press fit copper fittings intended to carry water or gas. Press fittings (also known as crimp fittings) are crimped, by the closure of a special jaw within a press machine, on to a tube. The crimping process mechanically locks a fitting on to a tube and presses a sealing ring within the fitting against the surface of a tube to make a seal between them.
Press fittings are quick to install and unlike solder fittings do not require the use of heat/blow torch to make a joint.
Who is BS 8537 for?
Fitting manufacturers in the UK, Europe and the Far East
Procurers of press fittings
Construction industry consulting engineers
Construction and engineering consultants
Mechanical service contractors
Local authorities.
BS 8537 gives methods of test for copper press end connections of plumbing fittings up to 108 mm in diameter, used for the purpose of joining copper tubes conforming to BS EN 1057 and non-copper metallic tubes that are intended for use in hot and cold water, heating and cooling systems, natural gas and liquefied petroleum gas systems.
BS 8537 is related to parts of the BS EN 1254 Copper and copper alloys. Plumbing fittings series of standards for copper and copper alloy fittings for joining metallic tubes or plastics pipes. BS EN 1254 is published in five parts:
Part 1: Fittings with ends for capillary soldering or capillary brazing to copper tubes
Part 2: Fittings with compression ends for use with copper tubes
Part 3: Fittings with compression ends for use with plastics pipes
Part 4: Fittings combining other end connections with capillary or compression ends
