Chimneys - Components - Concrete flue blocks
This document specifies the materials, dimensional and performance requirements for precast concrete flue blocks as defined in Clause 3 for use in chimneys. The flue blocks may be of single wall or multi wall construction. The standard does not apply to flue blocks with back ventilation.
This standard does not cover products designated wet (W) in conjunction with corrosion class 3.
The standard also specifies a type of flue block to dimensionally coordinate with masonry unit coursing height, referred to as a type B (Bonding block).
This European standard also applies to storey-height and flue blocks reinforced for handling.
NOTE Any reference to the term flue blocks implies both flue blocks and their fittings, except where otherwise indicated.

FprEN 1858:2015 (E) 5 Foreword This document (FprEN 1858:2015) has been prepared by Technical Committee CEN/TC 166 “Chimneys”, the secretariat of which is held by ASI. This document is currently submitted to Unique Acceptance Procedure. This document will supersede EN 1858:2008+A1:2011. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Regulation(s). For the relationship with the EU Regulations, see informative Annex ZA, which is an integral part of this standard. This document is one of a series of coordinated standards dealing with specification, design, testing and installation of chimneys, both single and multi-wall. The coordinated package of standards is further divided by material of construction and this document is one of a series of specifications and execution documents dealing with design and installation of concrete chimney products and systems. The standards in this series for concrete chimney products and systems are: — EN 1857, Chimneys — Components — Concrete flue liners; — EN 1858, Chimneys — Components — Concrete flue blocks; — EN 12446, Chimneys — Components — Concrete outer wall elements. The changes include the revision of Annex ZA in conformity with the CPR. In this document, Annexes A, C and D are normative (not forming part of the product specification) and Annexes B, E and ZA are informative. Note: Due to fact that the EC has not yet been able to confirm the financial commitment for the New Approach Consultants’ work in 2015, there are currently no New Approach Consultants in place for 2015. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met. This shall not prevent the processing of draft standards nor the offering of harmonized standards to the European Commission. In particular, draft standards can be sent to vote without Consultant assessment. This note will be removed from the Foreword of the finalized publication.

NOTE See Annex B for examples of typical flue block types. 7.1.2 Flue blocks shall have a maximum of four flues or ventilation passages. 7.2 Type B flue blocks 7.2.1 The co-ordinating height of Type B flue blocks shall be declared by the manufacturer. 7.2.2 When measured perpendicular to the axis of the flue for Type B flue blocks, the minimum dimensions of the flue shall be not less than 90 mm and the cross-sectional flue area shall be not less than 16 500 mm2. In transfer blocks the flue shall taper to a diameter of not less than 125 mm. 7.2.3 The bonding extension on a straight bonding Type B flue blocks shall not be less than 75 mm (see Clause B.3). kSIST FprEN 1858:2016

In addition, flue blocks and fittings having a compressive strength less than 10 MPa, or having a temperature designation above T250 and/or designated soot fire resistant shall meet the requirements of 8.5. When a flue block is multi-flued with an equal wall thickness, the heat stress test shall be carried out on the flue with the highest designation and temperature. 8.1.2 Flue block bends, made of the same material mix and by the same method of manufacture as the tested straight flue block shall be deemed to comply with the requirement in 8.1.1. 8.1.3 Flue block bends and fittings, made of a different material mix or using a different method of manufacture from those described in 8.1.2, shall be checked for heat stress resistance by testing a special straight test sample in accordance with 8.1.1. This straight test sample shall be made using the same material mix and manufacturing method as the bend or fitting. 8.1.4 The distance to combustible material, xx, shall be declared.

In addition, flue blocks and fittings having a compressive strength less than 10 MPa, or having a temperature designation above T250 and/or designated soot fire resistant shall meet the requirements of 8.5. 8.2.2 Flue block bends made of the same material mix and by the same method of manufacture as the tested straight flue block, shall be deemed to comply with the requirement in 8.4. 8.2.3 Flue block bends and fittings, made of a different material mix or using a different method of manufacture from those described in 8.2.1, shall be checked for heat shock by testing a special straight test in accordance with 8.1.1. 8.2.4 The distance to combustible material, xx, shall be declared. The maximum temperature measured on the surface of adjacent combustible materials shall not exceed 100 °C when related to an ambient temperature of 20 °C, when the test assembly is tested at the test temperature of 1000 °C over a period of 30 min.
