Systems for assessment and verification of performance constancy

The system of assessment and verification the constancy of performance is a procedure that is carried out with the aim of ensuring the compliance of the construction product with the performance of the essential characteristics specified in the declaration of performance that are determined in the corresponding technical specification, technical regulation or Serbian technical assessment.

On the basis of the Rulebook on the method of implementation and verification of constancy of performance of construction products ("Official Gazette of RS", No. 59 dated August 23, 2019) systems are classified as follows:

System 1+

Declaration of the performance of the construction product under the System 1+ is drawn up on the basis of the following items:

(1)         the manufacturer shall carry out:

(i)           factory production control;

(ii)          further testing of samples taken at the manufacturing plant by the manufacturer in accordance with the prescribed test plan.;

(2)         The notified product certification body shall decide on the issuing, restriction, suspension or withdrawal of the certificate of constancy of performance of the construction product on the basis of the outcome of the following assessments and verifications carried out by that body:

(i) an assessment of the performance of the construction product carried out on the basis of testing (including sampling), calculation, tabulated values or descriptive documentation of the product;

(ii) initial inspection of the manufacturing plant and of factory production control;

(iii) continuing surveillance, assessment and evaluation of factory production control;

(iv) audit — testing of samples taken by the notified product certification body at the manufacturing plant or at the manufacturer's storage facilities.

System 1

Declaration of the performance of the construction product under the System 1 is drawn up on the basis of the following items:

(1)         the manufacturer shall carry out:

(i)           factory production control;

(ii)          further testing of samples taken at the manufacturing plant by the manufacturer in accordance with the prescribed test plan.

(2)         The notified product certification body shall decide on the issuing, restriction, suspension or withdrawal of the certificate of constancy of performance of the construction product on the basis of the outcome of the following assessments and verifications carried out by that body:

(i) an assessment of the performance of the construction product carried out on the basis of testing (including sampling), calculation, tabulated values or descriptive documentation of the product; 

(ii) initial inspection of the manufacturing plant and of factory production control; 

(iii) continuing surveillance, assessment and evaluation of factory production control.

System 2+

Declaration of the performance of the construction product under the System 2 is drawn up on the basis of the following items:

(1)         the manufacturer shall carry out:

(i) an assessment of the performance of the construction product on the basis of testing (including sampling), calculation, tabulated values or descriptive documentation of that product; 

(ii) factory production control;

(iii) testing of samples taken at the manufacturing plant by the manufacturer in accordance with the prescribed test plan.

(2)         The notified factory production control certification body shall decide on the issuing, restriction, suspension or withdrawal of the certificate of conformity of the factory production control on the basis of the outcome of the following assessments and verifications carried out by that body:

(i)           initial inspection of the manufacturing plant and of factory production control;

(ii)          continuous surveillance, assessment and evaluation of factory production control.

System 3

Declaration of the performance of the construction product under the System 3 is drawn up on the basis of the following items:

(1)         the manufacturer shall carry out factory production control;

(2)         the notified laboratory shall assess the performance on the basis of testing (based on sampling carried out by the manufacturer), calculation, tabulated values or descriptive documentation of the construction product.

System 4

Declaration of the performance of the construction product under the System 4 is drawn up on the basis of the following items:

(1)         the manufacturer shall carry out:

(i)           an assessment of the performance of the construction product on the basis of testing, calculation, tabulated values or descriptive documentation of that product;

(ii)          factory production control;

(2)         No tasks require the intervention of notified bodies.
