CEN/TC 229/WG 4 - Products which do not warrant a specific standard and which could be referred to in specific standards

This document provides the specifications, the basic performance criteria and the Assessment and Verification of Constancy of Performance (AVCP) for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties (steel, polymer or other fibres) is also covered. It does not cover precast reinforced components of lightweight aggregate concrete with open structure nor glass-fibre reinforced concrete.
It can also be used to specify products for which there is no standard. Not all of the specifications (Clause 4) of this document are relevant to all precast concrete products.
Some European product standards refer to this document. They can include specific provisions that take precedence over the provisions of this document.

1.1   General
This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made according to the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer.
The report covers commonly used applications (walls/beams/columns and solid slabs and pipes). The range of these applications is further limited to prevent other types of failure than concrete breakout failure (cone failure), bond failure, failure of reinforcement or failure in the steel insert.
Due to lack of information this report does not cover double shell walls, floor plates and beams for beam-and-block floor systems.
The safety levels are given for information and are intended for short-term-handling and transient situations.
This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2013, 6.3) covering the insert embedment.
This Technical Report does not cover:
-   the design of the lifting inserts independently placed on the market;
-   lifting inserts for permanent and repeated use.
This Technical Report is prepared based on the fact that the anchorage in the concrete of parts of the lifting assembly is governed by the Construction Products Regulation. Lifting accessories independently placed on the market are governed by the Machinery Directive.
1.2   Types of inserts for lifting and handling
This Technical Report applies to the embedment of lifting inserts. Devices made by the precaster may consist of smooth bars, prestressing strands, steel plates with anchorage or steel wire ropes. The system devices may be e.g. internal threaded inserts, flat steel inserts and headed inserts.
Lifting loops of ribbed bars are not covered.
1.3   Minimum dimensions
This Technical Report applies in general to inserts with a minimum nominal diameter of 6 mm or the corresponding cross section. In general, the minimum anchorage depth should be hef = 40 mm.
Wire ropes of diameter less than 6 mm are not covered.

This document provides guidelines for the surface appearance of precast concrete products and the methods for inspecting and assessing the conformity of appearance for use in conjunction with specific product standards. This document may also be used to describe the appearance of products for which there is no standard.
If there is a specific standard for a precast concrete product, it takes priority over this document.

This document gives guidelines on how full-scale tests may be incorporated in product standards as a tool to reduce incertainties in resistance models.
This document also gives guidelines to designers setting up a proper test programme as part of the initial design of a component.

This document offers product category rules (PCR) guidance for the development of Type III environmental declarations for precast concrete products according to EN 15804.
This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and what quality data to be used in the development of EPDs.
Additional to the common parts of EN 15804, this European Standard for precast concrete products:
- defines the system boundaries;
- defines the modelling and assessment of material-specific characteristics;
- defines allocation procedures for multi-output processes along the production chain;
- defines allocation procedures for reuse and recycling;
- includes the rules for calculating the LCI and the LCIA underlying the EPD;
- provides guidance/specific rules for the determination of the reference service life (RSL);
- gives guidance on the establishment of default scenarios;
- gives guidance on default functional units for precast concrete products.
This document is intended to be used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intention is properly stated in the system boundary description.

This document specifies the requirements, the basic performance criteria and the Assessment and Verification of Constancy of Performance (AVCP) for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties (steel, polymer or other fibres) is also covered. It does not cover prefabricated reinforced components of lightweight aggregate concrete with open structure.
It may also be used to specify products for which there is no standard. Not all of the requirements (Clause 4) of this standard are relevant to all precast concrete products.
If a specific product standard exists, it takes precedence over this document.
The precast concrete products dealt with in this standard are factory produced for building and civil engineering works. This document can also be applied to products manufactured in temporary plants on site if the production is protected against adverse weather conditions and controlled following Clause 6 provisions.
The analysis and design of precast concrete products is not within the scope of this document but it does offer, for non-seismic zones, information about:
-   the choice of partial safety factors defined by the pertinent Eurocode;
-   the definition of some requirements for prestressed concrete products.

This European Standard specifies the requirements, the basic performance criteria and the evaluation of conformity for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206-1 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties steel, polymer or other fibres is also covered. It does not cover prefabricated reinforced components of lightweight aggregate concrete with open structure.

This Technical Report provides recommendations for the choice and use of cast-in steel lifting inserts, hereafter called 'inserts' for the handling of precast concrete elements. They are intended for use only during transient situations for lifting and handling, and not for the service life of the structure. The choice of insert is made according to the lifting capacity of their part embedded in the concrete, or may be limited by the capacity of the insert itself and the corresponding key declared by the insert manufacturer. The report covers commonly used applications (walls/beams/columns and solid slabs and pipes) and the range of these applications is further limited to prevent other types of failure than concrete breakout failure (cone failure), failure of supplementary reinforcement or failure in the steel insert. A basic supposition is that the concrete is demonstrably uncracked during all lifting situations.
The limitation in scope is used to obtain simple design models. Further information may be found in [1].
The recommended safety levels are intended for short-term-handling and transient situations.
This Technical Report applies only to precast concrete elements made of normal weight concrete and manufactured in a factory environment and under a factory production control (FPC) system (in accordance with EN 13369:2004, clause 6.3) covering the insert embedment.
This Technical Report does not cover :
-   The design of the insert itself (for inserts manufactured by insert suppliers).
-   The lifting key that hooks on to the embedded lifting insert as a component between the insert and the lifting machinery (crane, excavator...), nor its compliance with the embedded insert. These components, when brought to the market separately, are covered by the Machinery Directive (98/37/EC).
-   Lifting inserts for permanent and repeated use.
This report is not an interpretation of the Machinery Directive.
