(Amendment)Specification for ancillary components for masonry - Part 3: Bed joint reinforcement of steel meshwork
Specification for ancillary components for masonry - Part 3: Bed joint reinforcement of steel meshwork
This European Standard specifies the requirements for masonry bed joint reinforcement for structural use (see 5.2.1) and for non-structural use (see 5.2.2). Where products are intended for use in cavity wall construction, this European Standard covers only the performance of the meshwork as reinforcement in bed joints and not its performance as wall ties across the cavity. This European Standard is not applicable to: a) products in the form of individual bars or rods; b) products formed from materials other than specified grades of austenitic stainless steel, austenitic ferritic stainless steel, zinc pre-coated steel sheet or zinc coated steel wire with or without organic coating. NOTE Annex ZA refers only to welded wire meshwork intended for structural use referred to in 5.2.1 as there are no known regulated requirements for products of this family for non-structural use.

1 Modification to Clause 8
Delete Clause 8 entirely and replace it with the following:
"8 Assessment and verification of constancy of performance - AVCP
8.1 General
The compliance of bed joint reinforcement for structural use with the requirements of this standard and
with the performances declared by the manufacturer in the DoP shall be demonstrated by:
- determination of the product type;
- factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
NOTE The assignment of tasks to the notified body(ies) and the manufacturer is shown in Table ZA.2.
8.2 Type testing
8.2.1. General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same
AVCP system on the same product or products of similar design, construction and functionality, such
that the results are applicable to the product in question.
NOTE Same AVCP system means testing by an independent third party, under the responsibility of a notified
product certification body.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristic for all products within that same family
In addition, the determination of the product type shall be performed for all characteristics included in
the standard for which the manufacturer declares the performance:
- at the beginning of the production of a new or modified bed joint reinforcement of steel meshwork
(unless a member of the same product range), or
- at the beginning of a new or modified method of production (where this may affect the stated
properties); or
- they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the bed
joint reinforcement design, in the raw material or in the supplier of the components, or in the method of
production (subject to the definition of a family), which would affect significantly one or more of the
characteristics.

EN 845-3:2013/FprA1:2015 (E)
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics
need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the bed joint reinforcement manufacturer to ensure that bed joint
reinforcement as a whole is correctly manufactured and its component products have the declared
performance values.
8.2.2 Test samples, testing and compliance criteria
The minimum sample size of bed joint reinforcement for a single test shall be as given in Table 7 and
shall be drawn at random. For initial type testing, the batch from which the sample is drawn shall be of
a size of at least 100 times the number of specimens taken. Pre-production samples may be used for
initial type tests where it is possible to demonstrate that the characteristics of performance are
representative of products from the full production process.

In the event of the need to check the compliance of a lot or consignment of a product supplied to site or
installed, a sample shall be taken at random from the lot or consignment and tested. The sample sizes
shall be not less than those given in Table 7.
8.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All test reports
shall be retained by the manufacturer for at least 10 years after the last date of production of the bed
joint reinforcement of steel meshwork to which they relate.
8.2.4 Shared other party results
NOTE The sharing of other party results is in principle applicable to all systems of assessment and evaluation
of constancy of performance.

EN 845-3:2013/FprA1:2015 (E)
A manufacturer may use the results of the product type determination obtained by someone else (e.g.
by another manufacturer, as a common service to manufacturers, or by a product developer), to justify
his own declaration of performance regarding a product that is manufactured according to the same
design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same
kind, provided that:
– the results are known to be valid for products with the same essential characteristics relevant for
the product performance;
– in addition to any information essential for confirming that the product has such same
performances related to specific essential characteristics, the other party who has carried out the
1
determination of the product type concerned or has had it carried out, has expressly accepted to
transmit to the manufacturer the results and the test report to be used for the latter’s product type
determination, as well as information regarding production facilities and the production control
process that can be taken into account for FPC;
– the manufacturer using other party results accepts to remain responsible for the product having
the declared performances and he also:
– ensures that the product has the same characteristics relevant for performance as the one that has
been subjected to the determination of the product type, and that there are no significant differences
with regard to production facilities and the production control process compared to that used for the
product that was subjected to the determination of the product type; and
– keeps available a copy of the determination of the product type report that also contains the
information needed for verifying that the product is manufactured according to the same design and
with raw materials, constituents and manufacturing methods of the same kind.
8.3 Factory production control (FPC)
8.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products
placed on the market comply with the declared performance of the essential characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the
use of the results to control raw and other incoming materials or components, equipment, the
production process and the product.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a
systematic manner in the form of written policies and procedures.
This factory production control system documentation shall ensure a common understanding of the
evaluation of the constancy of performance and enable the achievement of the required product
performances and the effective operation of the production control system to be checked. Factory
production control therefore brings together operational techniques and all measures allowing
maintenance and control of the compliance of the product with the declared performances of the
essential characteristics.
In case the manufacturer has used shared product type results, the FPC shall also include the
appropriate documentation as foreseen in 8.2.4.

8.3.2.1 General
The manufacturer is responsible for organizing the effective implementation of the FPC system in line
with the content of this product standard. Tasks and responsibilities in the production control
organization shall be documented and this documentation shall be kept up-to-date.
The responsibility, authority and the relationship between personnel that manages, performs or verifies
work affecting product constancy, shall be defined. Th
