ISO 5725 Accuracy (trueness and precision) of measurement methods and results
ISO 5725-1:1994 Accuracy (trueness and precision) of measurement methods and results -- Part 1: General principles and definitions
The purpose is to outline the general principles to be understood when assessing accuracy (trueness and precision) of measurement methods and results, and in applications, and to establish practical estimations of the various measures by experiment. Is concerned exclusively with measurement methods which yield measurements on a continuous scale and give a single value as the test result. May be applied to a very wide range of materials, including liquids, powders and solid objects, manufactured or naturally occurring, provided that due consideration is given to any heterogeneity of the material.
ISO 5725-2:1994 Accuracy (trueness and precision) of measurement methods and results -- Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method
Amplifies the general principles to be observed in designing experiments for the numerical estimation of the precision of measurement methods by means of a collaborative interlaboratory experiment, provides a detailed practical description of the basic method for routine use in estimating the precision of measurement methods, provides guidance to all personnel concerned with designing, performing or analysing the results of the tests for estimating precision. Annex B provides practical examples of estimating the precision of measurement methods by experiment.
ISO 5725-3:1994 Accuracy (trueness and precision) of measurement methods and results -- Part 3: Intermediate measures of the precision of a standard measurement method
Specifies four intermediate measures due to changes in observation conditions (time, calibration, operator and equipment) within a laboratory. These intermediate measures can be established by an experiment within a specific laboratory or by an interlaboratory experiment. Furthermore, discusses the implications of the definitions of intermediate precision measures, presents guidance on the interpretation and application of the estimates of intermediate precision measures in practical situations, discusses the connections between trueness and measurement conditions.
ISO 5725-4:1994 Accuracy (trueness and precision) of measurement methods and results -- Part 4: Basic methods for the determination of the trueness of a standard measurement method
Provides basic methods for estimating the bias of a measurement method and the laboratory bias when a measurement method is applied. In order that the measurements are made in the same way, it is important that the measurement method has been standardized. Can be applied only if the accepted reference value can be established as a conventional true value, e.g. by measurement standards or suitable reference materials or by referring to a reference measurement method or by preparation of a known sample.
ISO 5725-5:1998 Accuracy (trueness and precision) of measurement methods and results -- Part 5: Alternative methods for the determination of the precision of a standard measurement method
ISO 5725-6:1994 Accuracy (trueness and precision) of measurement methods and results -- Part 6: Use in practice of accuracy values
The purpose is to give some indications of the way in which accuracy data can be used in various practical situations by: giving a standard method of calculating the repeatability limit, the reproducibility limit and other limits, providing a way of checking the acceptability of test results obtained under repeatability or reproducibility conditions, describing how to assess the stability of results within a laboratory over a period of time, describing how to assess whether a given laboratory is able to use a given standard measurement method in a satisfactory way, describing how to compare alternative measurement methods.

Wiley has long held a pre-eminent position as a publisher of books on geotechnical engineering, with a particular strength in soil behavior and soil mechanics, at both the academic and professional level. This reference will be the first book focused entirely on the unique engineering properties of residual soil. Given the predominance of residual soils in the under-developed parts of the United States and the Southern Hemisphere, and the increasing rate of new construction in these regions, the understanding of residual soils is expected to increase in importance in the coming years. This book will be written for the practicing geotechnical engineer working to any degree with residual soils. It will describe the unique properties of residual soil and provide innovative design techniques for building on it safely.The author will draw on his 30 years of practical experience as a practicing geotechnical engineer, imbuing the work with real world examples and practice problems influenced by his work in South America and Southeast Asia.
The pioneering guide that breaks ground on the unique engineering properties of residual soils
Geotechnical Engineering in Residual Soils digs deep to help enrich the reader's knowledge on the subject of soils—in particular, residual soils—as they pertain to engineering. Appearing mostly in underdeveloped parts of the United States and tropical countries, these soils are playing an increasingly important role in building designs as construction encroaches into these areas. In recognition of this fact, this guide equips geotechnical engineers with essentials for learning the concepts and principles of residual soil behavior—and serves as a starting point to assist them in pursuing innovative engineering strategies for working effectively with residual soils. Geotechnical Engineering in Residual Soils:
* Introduces geotechnical engineers to those aspects of residual soil behavior that they ought to be aware of when undertaking projects in these soils
* Highlights the mistaken interpretations of soil behavior that can result from the application to residual soils of traditional concepts derived from sedimentary soils
* Includes numerous illustrations throughout, specifically addressing the unique properties of residual soils
* Includes coverage of special topics, such as the role of negative pore pressure above the water table, the influence of weather conditions on soil behavior, the properties of volcanic soils, and compaction of residual soils
* Is written by an author with more than thirty years of firsthand experience analyzing and designing for construction on residual soils
Thorough and insightful, Geotechnical Engineering in Residual Soils delivers a fresh overview on understanding the structural and mechanical properties of soils from an engineering perspective—and informs readers how to solidify design approaches to set their projects on a sure footing.

BS 6375:2009 part 1, 2 and 3 Performance of windows and doors
BS 6375-1:2009 Performance of windows and doors. Classification for weathertightness and guidance on selection and specification
BS 6375 gives guidance on how to apply BS EN 14351. BS 6375-1 specifies the exposure categories related to test pressure levels for air permeability, watertightness and wind resistance for external windows and doorsets. It applies to all types of vertical windows and doorsets, and includes windows in which the opening lights are not fully framed, e.g. adjustable glass louvres. It is also relevant to both factory-glazed and site-glazed products.
BS 6375 provides advice on the selection of performance characteristics for windows and doorsets intended for the UK market. The full range of characteristics is also provided in the various parts of BS EN 14351.
BS EN 14351 has to be referenced if windows and doors are to be CE marked. Not all the characteristics listed in BS EN 14351 are required for CE marking, and of those that are required, only those mandated (i.e. covered by national building regulations) in the UK need be declared. Manufacturers wishing to CE mark products are advised to seek advice from the relevant national regulatory authority.
The majority of characteristics identified in BS EN 14351 have a number of performance levels. BS 6375 provides guidance to the specifier and the manufacturer on an appropriate level for the UK market.
BS EN 14351 and BS 6375 cover a range of products and characteristics and are therefore divided into parts. BS EN 14351 is divided into product groups and BS 6375 is divided into performance characteristics. Not all characteristics will apply to all product groups or to all end uses. In addition, BS 6375 may be used for product groups not covered by BS EN 14351.
This part of BS 6375 supersedes BS 6375-1:2004, which is withdrawn.
The main changes to BS 6375-1 include:
Revision of the foreword to align with Parts 2 and 3 of BS 6375-1
Clarification of the air permeability tests and requirements
Tests previously required by PAS 23-1 for entrance doorsets have been included.
BS 6375-2:2009 Performance of windows and doors. Classification for operation and strength characteristics and guidance on selection and specification
As part of the BS 6375 series of standards, BS 6375-2 is the national application document for BS EN 14351. It identifies the characteristics and classes of performance appropriate for windows and internal/external pedestrian doorsets intended for the UK.
BS 6375-2 specifies performance requirements for the operation and strength of manually operated windows and internal/external pedestrian doorsets in their fully finished condition.
BS 6375-2 replaces BS 6375-2:1987, which is withdrawn.
This full revision of BS 6375-2 includes the following changes:
The standard now refers to European test methods and classes of performance. It identifies those performance classes that are applicable to the UK market.
Tests previously required by PAS 23-1 for entrance doorsets have been included, although some minor changes to acceptable performance levels have been made.
BS 6375-3:2009 Performance of windows and doors. Classification for additional performance characteristics and guidance on selection and specification
BS 6375-3 is a new addition to the BS 6375 series of standards. It identifies those characteristics covered by BS EN 14351 that are not discussed in the other parts of BS 6375.
This standard includes information on:
Resistance to snow and permanent loads
Fire and security issues
What should be agreed between a manufacturer and purchaser.
