The purpose of this document is to provide the principles and guidance for the preparation of extended application documents for combined penetration seals where the systems were tested in accordance with EN 1366-1, EN 1366-2 and EN 1366-3. The field of the extended application document is additional to the direct field of application given within EN 1366-1, EN 1366-2 and EN 1366-3 and can be applied on a number of tests from each standard, which provide the relevant information for the formulation of an extended application.

This EXAP is intended to allow the penetration sealing of more than one service (e.g. Cables, Pipes, Conduits, Fire resisting ducts and Fire dampers) in the same penetration.

This document specifies test methods for measuring the Head Injury Criterion (HIC) of sports surfaces. Two different methods are specified. In Procedure A, a series of tests are undertaken from differing drop heights and the HIC values are plotted, and the Critical Fall Height determined. In Procedure B, a series of tests are made at a fixed drop height and the mean value of HIC is calculated.

This test method is primarily intended for use on synthetic turf sport surfaces. It may be carried out in a laboratory on test specimens or in situ on installed sports surfaces.

NOTE          Annex A contains an indicative test method where a single test is made at each drop height and an indicative value of HIC is calculated. This test method can also be used on other forms of sports surfacing that may be intended to provide impact protection against head impacts.

This document:

—    specifies requirements for dimensions, adhesion of yarns and grades of colour fastness to light;

—    gives the symbols, to be used for marking purposes, for some of these characteristics and also for matching, methods of application and removal;

—    specifies requirements for marking;

—    gives the designation system.

The marking requirements of this document are primarily for the information of the consumer and to enable optimum use of the product.

This document applies to textile wallcoverings supplied in rolls for hanging on to walls and ceilings by means of an adhesive covering the whole of the interface between the wallcovering and the support surface.

Excluded from this document are rigid materials, materials not attached or not wholly attached by adhesive, and non-decorative wallcoverings such as wall linings or those with special properties, e.g. thermal or acoustic insulation.

This document provides principles and requirements for the assessment of environmental, social and economic performance of buildings and civil engineering works taking into account their technical characteristics and functionality. Assessments of environmental, social and economic performance are the three aspects of sustainability assessment of buildings and civil engineering works, or combination thereof, (hereafter referred to as “construction works”).

The framework applies to all types of construction works, both new and existing, and it is relevant for the assessment of the environmental, social and economic performance of new construction works over their entire life cycle, and of existing construction works over their remaining service life and end of life stage.

The sustainability assessment of construction works concentrates on the assessment of environmental, social and economic aspects and impacts of construction works expressed with quantifiable indicators. It includes the assessment of a construction works’ influence on the environmental, social and economic aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the curtilage of the building and the civil engineering works. It excludes environmental, social and economic risk assessment.

The European Standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods; nor do they prescribe levels or classes for measuring performance.

NOTE          Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for environmental, social and economic performance in the client’s brief, construction regulations, national standards, national codes of practice, construction works assessment and certification schemes, etc.

The rules for assessment of environmental, social and economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the environmental, social and economic performance of the object of assessment are taken into account.

(1) The basis for the design of building and civil engineering works in masonry is given in this Part 1-1 of EN 1996, which deals with unreinforced masonry, reinforced masonry and confined masonry. Principles for the design of prestressed masonry are also given. This Part 1-1 of EN 1996 is not valid for masonry elements with a plan area of less than 0,04 m2.

(2) Part 1-1 of EN 1996 gives detailed rules which are mainly applicable to ordinary buildings. The applicability of these rules can be limited, for practical reasons or due to simplifications; any limits of applicability are given in the text where necessary.

(3) Execution is covered to the extent that is necessary to indicate the quality of the construction materials and products that to be used and the standard of workmanship on site needed to comply with the assumptions made in the design rules.

(4) For those types of structures not covered entirely, for new structural uses for established materials, for new materials, or where actions and other influences outside normal experience have to be resisted, the provisions given in this Part 1-1 of EN 1996 can be applied, but with possible need for supplements.

(5) Part 1-1 of EN 1996 does not cover:

—    resistance to fire (which is dealt with in EN 1996-1-2);

—    particular aspects of special types of building (for example, dynamic effects on tall buildings);

—    particular aspects of special types of civil engineering works (such as masonry bridges, dams, chimneys or liquid-retaining structures);

—    particular aspects of special types of structures (such as arches or domes);

—    masonry where gypsum, with or without cement, mortars are used;

—    masonry where the units are not laid in a regular pattern of courses (rubble masonry);

—    masonry reinforced with other materials than steel.

This International Standard specifies operational activities, overall alarming, fault detection and diagnostics, reporting, monitoring, energy management functions, functional interlocks and optimizations to set and maintain energy performance of buildings.

Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in ISO 52000‑1:2017.

NOTE 1   In ISO/TR 52000‑2:2017 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying Technical Reports that are published or in preparation.

NOTE 2   The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
