6 Assessment and verification of constancy of performance – AVCP
The technical details necessary for the implementation of the system of assessment and verification of constancy of performance comprise provisions with regards to:
— the assessment of the performance of the construction product, which may be carried out on the basis of testing (including sampling), calculation, tabulated values or descriptive documentation of the product; and
— the applicable factory production control.
6.2 Assessment of performance
When the intention is to declare any performance related to characteristics included in Annex ZA, this shall be carried out on the basis of testing (including sampling), calculation, tabulated values or descriptive documentation of the product, in accordance with Clauses 4 and 5.
Assessment previously performed in accordance with the provisions of this document. may be considered, provided that this assessment was performed to the same or a more rigorous assessment 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.
For the purposes of assessment, the 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.
NOTE Products may be grouped into different families for different characteristics.
In addition, the determination of the product performance shall be
— carried out for all characteristics included in the standard for which it is intended to declare the performance:
— on first application of this document, or
— at the beginning of the production of a new or modified thermoplastics rigid protective wallcovering panel, unless a member of the same product family; or
— at the beginning of a new or modified method of production, where the modification may affect the stated properties;
— repeated for the characteristic(s) in question, whenever a change occurs in the thermoplastics rigid protective wallcovenng panel design, in the raw material(s) or in the supplier of the components. and/or in the method of production (subject to the definition of a family), which may affect significantly the performance En relation to one or more of the characteristics.
Where kit components are used whose performance in relation to their characteristics has already been determined on the basis of assessment methods of other harmonised technical specifications and those components bear CE marking in accordance with those harmonised technical specifications, these performances do not need to be re-assessed, if the intended use and the assessment methods of this document correspond to previously used. The specifications of these components shall be documented.
6.2.2 Test samples, testing and assessment criteria
The samples of thermoplastics rigid protective wallcovering panels to be tested/assessed shall be in accordance with Table 4.
An FPC system shall be established, documented, operated and maintained to ensure that the products placed on the market comply with the declared performance in relation to 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 and provisions shall be documented in a systematic manner in the form of written policies and procedures.
The responsibility, authority and the relationship between personnel that manages, performs or verifies work affecting constancy of the performance of the product, shall be defined.
The qualification and competence (e.g. on the basis of education, training, skills, or experience) of personnel performing tasks affecting the assessment and verification of constancy of performance of the product shall be recorded.
Documents defining the factory production control system shall be drawn up and kept up-to-date. Documentation and procedures should be appropriate to the product and production 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 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, correct the effects of such deviations, treat any resulting instances of non-conformity and, if necessary, revise the FPC system to rectify the cause of non-constancy of performance.
All weighing, measuring and testing equipment shall be checked, calibrated and regularly inspected according to documented procedures, frequencies and criteria.
All equipment used in the production process shall be regularly inspected and maintained to ensure use, wear or failure does not cause inconsistency in the production process. Inspections and maintenance shall be carried out and recorded in accordance with written procedures and the records retained for the period defined in the FPC procedures.
220.127.116.11 Raw materials and components
The specifications of all incoming raw materials and components shall be documented, as shall the inspection scheme for ensuring their compliance.
18.104.22.168 Traceability and marking
Individual product batches shall be identifiable and traceable with regard to their place of their production.
Written procedures ensuring that processes related to affixing traceability codes and/or markings are inspected regularly shall be maintained.
22.214.171.124 Product testing and evaluation
Procedures to ensure that the performance in relation to the declared characteristics are maintained shall be established. The characteristics, and the means of control, are:
— reaction to fire: shall be subject to the tests indicated in 5.1, at least once every 10 years;
— emission of dangerous substances into indoor air: shall be subject to the tests indicated in 5.2 and 5.3, at least once every 10 years;
— migration of heavy metals: shall be subject to the tests indicated in 5.4, at least once every 10 years;
— impact resistance: shall be subject to the tests indicated in 5.5, at least once every 5 years;
— sound absorption: shall be subject to the tests indicated in 5.6, at least once every 10 years;
— thermal resistance: shall be subject to the tests indicated in 5.7, at least once every 10 years.
6.3.2 Initial inspection of factory and of FPC
Initial inspection of factory and of FPC shall be carried out when the production process has been finalized and in operation. The factory and FPC documentation shall be assessed to verify that the provisions of 126.96.36.199 to 188.8.131.52 are fulfilled.
During the inspection it shall be verified:
a) that all resources necessary for the assessment of the performance in relation to the product characteristics to be declared by the manufacturer are in place and correctly implemented,
b) that the FPC-procedures in accordance with the FPC documentation are followed in practice.
All locations where final assembly or at least final testing of the relevant product is performed, shall be assessed to verify that the above conditions a) and b) are in place and implemented. If the FPC system covers more than one product, production line or production process, and it is verified that the general provisions are fulfilled when assessing one product, production line or production process, the assessment of the general provisions does not need to be repeated when assessing the FPC for another product, production line or production process.BS EN 17104 pdf free download.Thermoplastics rigid protective wallcovering panels for internal use in buildings
