Scope

This European Standard specifies requirements, assessment methods, compliance criteria and a designation system for compression fittings for use with copper tubes. Compression fittings exist with sealing elements metallic and/or non-metallic - called non manipulative (commonly referenced as type A) and without sealing elements, called manipulative (commonly referenced as type B). For the purposes of joining copper tubes, the fitting ends have a size range from 6 mm to 108 mm. The compression fittings are designed for a service lifetime up to fifty years. This European Standard applies to fittings made of materials listed in CEN/TS 13388. Compression fitting ends, Type A, are suitable for use with copper tubes to EN 1057 in all material hardness conditions.

4.13 Tube / pipe abutment This requirement only applies to all fittings ends except threaded ends. Fitting ends are usually manufactured with an abutment to limit tube insertion (see Figure 1) and to assure that the minimum length of engagement is satisfied. Fittings may be produced for special purposes, particularly useful for repairs, where the fitting ends do not incorporate abutments, allowing for the fitting to slide along a tube. If the fitting has an abutment, the dimensions of the abutment must be so that if the smallest possible tube according to EN1057:2006 Table 4 or pipe is introduced, it shall be stopped. The abutment shall also satisfy the minimum bore requirement to minimize pressure drop and assure a sufficient flow rate as stated in clause 4.11.

Assessment and verification of constancy of performance - AVCP

6.1

General

The compliance of compression fittings for use with copper tubes 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).

6.2

Type testing

6.2.1

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, classified without further testing (CWFT) 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 [only for products covered by system 1+, 1 and 3], under the responsibility of a notified product certification body [only for products covered by system 1+ and 1].

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 characteristics for all products within that same family. NOTE

Products may be grouped in different families for different characteristics.

NOTE Reference to the assessment method standards should be made to allow the selection of a suitable representative sample.

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 compression fittings for use with copper tubes (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 compression fittings for use with copper tubes 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. 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.

17

prEN 1254-2:2015 (E)

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 compression fittings for use with copper tubes manufacturer to ensure that the compression fittings for use with copper tubes as a whole is correctly manufactured and its component products have the declared performance values. 6.2.2

Test samples, testing and compliance criteria

prEN 1254-2:2015 (E)

6.3.2

Requirements

6.3.2.1 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. This applies in particular to personnel that need to initiate actions preventing product non-constancies from occurring, actions in case of non-constancies and to identify and register product constancy problems. Personnel performing work affecting the constancy of performance of the product shall be competent on the basis of appropriate education, training, skills and experience for which records shall be maintained. In each factory the manufacturer may delegate the action to a person having the necessary authority to: 

identify procedures to demonstrate constancy of performance of the product at appropriate stages;



identify and record any instance of non-constancy;



identify procedures to correct instances of non-constancy.

The manufacturer shall draw up and keep up-to-date documents defining the factory production control. The manufacturer's documentation and procedures should be appropriate to the product and manufacturing process. The FPC system should achieve an appropriate level of confidence in the constancy of performance of the product. This involves: a)

the preparation of documented procedures and instructions relating to factory production control operations, in accordance with the requirements of the technical specification to which reference is made;

b)

the effective implementation of these procedures and instructions;

c)

the recording of these operations and their results;

d)

the use of these results to correct any deviations, repair the effects of such deviations, treat any resulting instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-constancy of performance.

Where subcontracting takes place, the manufacturer shall retain the overall control of the product and ensure that he receives all the information that is necessary to fulfil his responsibilities according to this European Standard. If the manufacturer has part of the product designed, manufactured, assembled, packed, processed and/or labelled by subcontracting, the FPC of the subcontractor may be taken into account, where appropriate for the product in question. The manufacturer who subcontracts all of his activities may in no circumstances pass the above responsibilities on to a subcontractor.

Product specific requirements

The FPC system shall address this European Standard and ensure that the products placed on the market comply with the declaration of performance. The FPC system shall include a product specific FPC, which identifies procedures to demonstrate compliance of the product at appropriate stages, i.e.: a)

the controls and tests to be carried out prior to and/or during manufacture according to a frequency laid down in the FPC test plan,

and/or

22

prEN 1254-2:2015 (E)

b)

the verifications and tests to be carried out on finished products according to a frequency laid down in the FPC test plan.

If the manufacturer uses only finished products, the operations under b) shall lead to an equivalent level of compliance of the product as if FPC had been carried out during the production. If the manufacturer carries out parts of the production himself, the operations under b) may be reduced and partly replaced by operations under a). Generally, the more parts of the production that are carried out by the manufacturer, the more operations under b) may be replaced by operations under a). In any case the operation shall lead to an equivalent level of compliance of the product as if FPC had been carried out during the production. NOTE Depending on the specific case, it can be necessary to carry out the operations referred to under a) and b), only the operations under a) or only those under b).

The operations under a) refer to the intermediate states of the product as on manufacturing machines and their adjustment, and measuring equipment etc. These controls and tests and their frequency shall be chosen based on product type and composition, the manufacturing process and its complexity, the sensitivity of product features to variations in manufacturing parameters etc. The manufacturer shall establish and maintain records that provide evidence that the production has been sampled and tested. These records shall show clearly whether the production has satisfied the defined acceptance criteria and shall be available for at least three years. 6.3.4

Procedure for modifications

If modifications are made to the product, production process or FPC system that could affect any of the product characteristics declared according to this standard, then all the characteristics for which the manufacturer declares performance, which may be affected by the modification, shall be subject to the determination of the product type, as described in 6.2.1. Where relevant, a re-assessment of the factory and of the FPC system shall be performed for those aspects, which may be affected by the modification. All assessments and their results shall be documented in a report. 6.3.5 One-off products, pre-production products (e.g. prototypes) and products produced in very low quantity The compression fittings for use with copper tubes produced as a one-off, prototypes assessed before full production is established, and products produced in very low quantities (less or equal than 1000 per year) shall be assessed as follows. For type assessment, the provisions of 6.2.1, 3 provisions:

rd

paragraph apply, together with the following additional



in case of prototypes, the test samples shall be representative of the intended future production and shall be selected by the manufacturer;



on request of the manufacturer, the results of the assessment of prototype samples may be included in a certificate or in test reports issued by the involved third party.

The FPC system of one-off products and products produced in very low quantities shall ensure that raw materials and/or components are sufficient for production of the product. The provisions on raw materials and/or components shall apply only where appropriate. The manufacturer shall maintain records allowing traceability of the product.

23

prEN 1254-2:2015 (E)

For prototypes, where the intention is to move to series production, the initial inspection of the factory and FPC shall be carried out before the production is already running and/or before the FPC is already in practice. The following shall be assessed: 

the FPC-documentation; and



the factory.

In the initial assessment of the factory and FPC it shall be verified: a)

that all resources necessary for the achievement of the product characteristics included in this European Standard will be available, and

b)

that the FPC-procedures in accordance with the FPC-documentation will be implemented and followed in practice, and

c)

that procedures are in place to demonstrate that the factory production processes can produce a product complying with the requirements of this European Standard and that the product will be the same as the samples used for the determination of the product type, for which compliance with this European Standard has been verified.

Once series production is fully established, the provisions of clause 6.3 shall apply.

Classification and designation

Compression fittings for use with copper tube shall be designated by quoting: a)

common term describing the pattern (eg. coupling, bend, elbow, tee, etc.);

b)

reference to this European Standard;

c)

the nominal outside diameter of the connecting tube/pipe or, in the case of fittings incorporating threaded connections, by the thread designation (see NOTE 1 for sequence of specifying ends);

d)

without abutment, if applicable;

e)

if required, the grade of dezincification resistance acceptance criteria;

f)

if required, the type of plating or coating.

NOTE 1 The preferred sequence a) for specifying ends is run-run-branch-branch (omitting where necessary for tees). The non preferred sequence b) is run-branch-run-branch (omitting where necessary for tees). Ordering details should state if the non preferred sequence system was used. NOTE 2 For fittings with equal ends, the nominal size can be specified by the one diameter. For fittings with unequal ends, the largest size should be quoted first. For adaptor fittings, the ends are specified in the same order, but the largest end of the run should be quoted first. EXAMPLE
