BS 6173:2009 Specification for installation and maintenance of gas-fired catering appliances for use in all types of catering establishments (2nd and 3rd family gases)
BS 6173 is a key standard for all gas installers.
BS 6173 specifies requirements for the installation, servicing and maintenance of new and previously-used gas-fired catering appliances used in catering establishments, burning 2nd or 3rd family gases.
The main changes to the standard include updates to installation practice and legislation.
BS 6173 does not apply to LPG catering installations where appliances are sited temporarily in the open air, marquees or tents, or to LPG installations in mobile catering vehicles.
BS 6173 does apply to the installation of typical domestic cookers or leisure appliances such as barbecues when installed in commercial catering sites or establishments. It is not intended to apply to primarily domestic premises, e.g. those supplying a small number of clients on a “bed and breakfast” basis. However, the general rules for hygiene and personal safety should be applied. It covers a wide range of appliances, such as cookers, fish and chip frying ranges, fryers, ovens, café boilers and urns, bain-marie units, tandoori ovens, kebab grills and barbecues.
BS 6173:2009 replaces BS 6173:2001, which is now withdrawn.

This European Standard specifies a method for determining the compressive strength of mortars and concretes for structural and non-structural repair, as defined in EN 1504-1.
The method applies to all types of repair mortar and concrete with a maximum aggregate size of 8 mm. It distinguishes between mortar with hydraulic and polymer binders. Hereafter, the term mortar refers to both mortars and concretes.
NOTE For repair mortars and concretes with aggregate in excess of 8 mm in size, conventional concrete test methods according to prEN 206 are used.

Service life estimation and extension of civil engineering structures
Author: Edited by V M Karbhari, L S Lee | Size: 5.6 MB | Format:PDF | Publisher: Woodhead Publishing Limited | Year: December 2010 | pages: 312 | ISBN: ISBN 1 84569 398 1 ISBN-13: 978 1 84569 398 5
- a single source of information on the service life of reinforced concrete and fibre-reinforced polymer (FRP) rehabilitated structures
- examines degradation mechanisms in composites for rehabilitation considering uncertainties in FRP reliability
- provides an overview of probabilistic methods for rehabilitation and service life estimation of corroded structures
Service life estimation is an area of growing importance in civil engineering both for determining the remaining service life of civil engineering structures and for designing new structural systems with well-defined periods of functionality. Service life estimation and extension of civil engineering structures provides valuable information on the development and use of newer and more durable materials and methods of construction, as well as the development and use of new techniques of estimating service life.
Part one discusses using fibre reinforced polymer (FRP) composites to extend the service-life of civil engineering structures. It considers the key issues in the use of FRP composites, examines the possibility of extending the service life of structurally deficient and deteriorating concrete structures and investigates the uncertainties of using FRP composites in the rehabilitation of civil engineering structures. Part two discusses estimating the service life of civil engineering structures including modelling service life and maintenance strategies and probabilistic methods for service life estimation. It goes on to investigate non-destructive evaluation and testing (NDE/NDT) as well as databases and knowledge-based systems for service life estimation of rehabilitated civil structures and pipelines.
With its distinguished editors and international team of contributors Service life estimation and extension of civil engineering structures is an invaluable resource to academics, civil engineers, construction companies, infrastructure providers and all those with an interest in improving the service life, safety and reliability of civil engineering structures.

Author: Simon Robinson, Ross Dixon, Christopher Preece, Krisen Moodley | Size: 1.5 MB | Format:PDF | Publisher: A Butterworth-Heinemann Title | Year: 30 Jan 2007 | pages: 259 | ISBN: ISBN-10: 0750667419 ISBN-13: 978-0750667418
Product Description
Engineering, as a profession and business, is at the sharp end of the ethical practice. Far from being a bolt on extra to the 'real work' of the engineer it is at the heart of how he or she relates to the many different stakeholders in the engineering project.
Engineering, Business and Professional Ethics highlights the ethical dimension of engineering and shows how values and responsibility relate to everyday practice. Looking at the underlying value systems that inform practical thinking the book offers a framework for ethical decision-making.
Covering global corporate responsibility to the increasing concern for the environment within the engineering business, the book offers ways in which value conflict can be handled. Integrating practice, value and diversity the book helps to prepare the engineer for the ethical challenges of the 21st century.
This book is essential reading for all students on courses accredited by the Engineering Council e.g. Civil, Chemical, Mechanical and Environmental Engineering who need to be aware of ethics. Also of interest to practicing engineers and professionals such as Sustainability Managers and Community Workers involved in engineering projects.
The authors have worked together in the area of engineering, professional and business ethics for many years and are all members of the National Centre for Applied Ethics at the University of Leeds.
* Integrates ethical considerations into everyday decision-making
* Shows how to review and overcome professional ethical problems
* Practical case studies and examples throughout

A complete introduction to the multidisciplinary applications of mathematical methods
In order to work with varying levels of engineering and physics research, it is important to have a firm understanding of key mathematical concepts such as advanced calculus, differential equations, complex analysis, and introductory mathematical physics. Essentials of Mathematical Methods in Science and Engineering provides a comprehensive introduction to these methods under one cover, outlining basic mathematical skills while also encouraging students and practitioners to develop new, interdisciplinary approaches to their research.
The book begins with core topics from various branches of mathematics such as limits, integrals, and inverse functions. Subsequent chapters delve into the analytical tools that are commonly used in scientific and engineering studies, including vector analysis, generalized coordinates, determinants and matrices, linear algebra, complex numbers, complex analysis, and Fourier series. The author provides an extensive chapter on probability theory with applications to statistical mechanics and thermodynamics that complements the following chapter on information theory, which contains coverage of Shannon's theory, decision theory, game theory, and quantum information theory. A comprehensive list of references facilitates further exploration of these topics.
Throughout the book, numerous examples and exercises reinforce the presented concepts and techniques. In addition, the book is in a modular format, so each chapter covers its subject thoroughly and can be read independently. This structure affords flexibility for individualizing courses and teaching.
Providing a solid foundation and overview of the various mathematical methods and applications in multidisciplinary research, Essentials of Mathematical Methods in Science and Engineering is an excellent text for courses in physics, science, mathematics, and engineering at the upper-undergraduate and graduate levels. It also serves as a useful reference for scientists and engineers who would like a practical review of mathematical methods.
