BS EN 13813:2002 Screed material and floor screeds - Screed material - Properties and requirements
This European Standard specifies requirements for screed material for use in floor construction internally. To support the aim of achieving a performance related standard, as far as practicable this standard refers only to the properties of the product and not to its method of manufacture, except when this is unavoidable in the description of the characteristics of the product. It defines for fresh screed material the performance related to setting time, consistency, pH value and for the hardened screed material, compressive strength, flexural strength, wear resistance, surface hardness, resistance to indentation, resistance to rolling wheel, shrinkage and swelling, modulus of elasticity, bond strength, impact resistance, reaction to fire, acoustic performance, thermal resistance and chemical resistance. It provides for the evaluation of conformity of the product to this European Standard. The marking requirements for products covered by this European Standard are included. This standard covers screed materials as defined in EN 13318. Structural screeds, i.e. those that contribute to the load bearing capacity of the structure, are excluded from this standard.
NOTE This standard can be used in conjunction with codes of application and national specifications for site made screed material produced and laid by the same

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.
