This document specifies a method for determining the ability of a covering to protect underlying materials against damage during a specified fire exposure.

The document is not used for the evaluation of fire resistance classifications (e.g. EI, EW, E,…) or reaction to fire classifications (according to EN 13501‑1).

The fire protection ability is nullified by the presence of combustible materials in the cavity behind the covering. The applicability of the results is limited according to the quantity and position of such combustible materials within that cavity.

NOTE          The amount of combustible materials permissible in the cavity is generally laid down in national regulations.

This document specifies a method for the determination of the softening point of bitumen and bituminous binders in the range of 28 °C to 150 °C.

The method described also applies to bituminous binders that have been recovered from bituminous mixes, e.g. by extraction according to EN 12697‑3 [1].

The change from mercury thermometers to electronic temperature devices has revealed that the temperature definition in the mercury thermometer has not been precise enough to make a correct, unbiased transfer to electronic devices. Care should be taken for softening points ring and ball above 100 °C as the condition may have changed from previous practice to present days testing equipment. Below approximately 100 °C the difference in temperature readings between electronic and mercury stem thermometer is acceptable compared to the repeatability of this test method.

WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

This document defines the functional and performance requirements and associated tests for Galileo timing receivers. The approach for this document is that of a performance based, meaning that no specific algorithm implementation is required. Instead, performance requirements are defined together with a corresponding test suite for verification.

The subject of this document is the Galileo chipset. Other sensors and/or additional processing that a higher synchronization Unit can implement on top of the Galileo chipset are not the subject of this document.

This document covers the following aspects related to Galileo timing receivers:

—    GNSS constellations and frequencies processed: Galileo Dual-Frequency. Other modes are optional, as explained below;

—    time scales, including Galileo System Time and Universal Time Coordinate;

—    Services Levels, this document covers the 2 levels of Service for GST and for UTC to be provided by Galileo Time Service in the first place. The document also anticipates a third Service Level to be provided in the future, for which an update of the document will be needed;

—    user dynamics: fixed users, defined as static users with precise knowledge of the antenna position, is the baseline mode;

—    processing of Timing Service Message disseminated by the Galileo System;

—    local timing integrity barriers: As a minimum, Time Receiver Autonomous Integrity Monitoring processing (T-RAIM);

—    robustness to interferences;

—    Galileo Open Service Navigation Message Authentication processing;

—    robustness to multipath.

This document does not cover the processing of GPS constellation but this does not preclude Manufacturers to implement GPS processing within the Galileo timing receivers, even if not addressed in this document. The use of other GNSS constellations is not forbidden by this document but the requirements and tests are defined considering Galileo-only, including those related to the integrity of the timing solution.

Single-Frequency modes are not covered by this document. This does not preclude manufacturers to implement single-frequency modes within the Galileo timing receivers, even if not addressed in this document, as a back-up of the nominal Dual-Frequency mode, and reversion mechanisms. It is important to remark that the integrity of the timing solution is only specified for Galileo Dual-Frequency mode.

The Galileo timing receivers addresses only users operating in static conditions. Moving users are not considered as part of this document.

On top of the functional requirements, performance requirements are defined in this document in terms of different key performance indicators such as:

—    accuracy, availability and integrity requirements;

—    local barriers, T-RAIM performances.

This document also provides the verification matrix and defines the test suite to verify the most fundamental requirements of the Galileo timing receivers.

Finally, this document provides a section dedicated to guidelines for the installation and maintenance of the Galileo timing receivers. This is a comprehensive section, including provisions for the antenna, cabling and receiver installation, as well as the calibration of time delays.

This document applies to unplasticized poly(vinyl chloride) (PVC-U) profiles that are intended to be used for the fabrication of windows and doors in accordance with the EN 14351 series or EN 16034, shutters according to EN 13659 and other construction profiles in accordance with the EN 13245 series. Furthermore, this document is also applicable for profiles used in other PVC-U products, which can include recyclates. This document gives references and specifies general and product-specific design for recycling principles.

NOTE 1       In this document, the term “PVC-U profiles” is used to refer to construction profiles made from PVC-U, PVC-UE, and PVC-U-based natural fibre composites (NFC).

Criteria for the use of materials, process conditions, and recyclability are defined, which are considered during the design process.

This document defines principles to

—    obtain the highest possible share of recyclability of the PVC-U part in the profile, and

—    increase the share of PVC-U recyclate in the profile,

while complying with requirements for the final product, where existent and defined elsewhere. This document establishes flowcharts which help to assess, (i) how recyclability is evaluated and (ii) whether inclusion of rPVC-U is possible.

The following components of the final PVC-U construction product are considered in this document:

—    profiles;

—    reinforcements;

—    gaskets;

—    insulations;

—    coverings.

This document specifies only the technical connection of the profile to other components (such as glazing or hardware) and their impact on the recyclability of the PVC-U profiles. The recyclability of the other components (e.g. glazing, aluminium cover, hardware) is excluded from this document.

NOTE 2       Examples for profiles included in this document and their intended use can be found in Figure 1.

This document describes a safety communication layer (services and a protocol) for the exchange of safety data using IEC 62541 mechanisms. It identifies the principles for functional safety communications defined in IEC 61784‑3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only.

NOTE 1 This document targets controller-to-controller communication. However, easy expandability to other use-cases (e.g. OPC UA field level communication) has already been considered in the design of this document.

NOTE 2 This document does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.

This document defines mechanisms for the transmission of safety-relevant messages among participants within a network using OPC UA technology in accordance with the requirements of IEC 61508 series and IEC 61784-3 for functional safety. These mechanisms may be used in various industrial applications such as process control, manufacturing, automation, and machinery.

This document provides guidelines for both developers and assessors of compliant devices and systems.

NOTE 3 The resulting SIL claim of a system depends on the implementation of this document within the system – implementation of this document in a standard device is not sufficient to qualify it as a safety device.
