Products Research Division

Major Objectives of Quality System

  • to perform fire tests of materials and products applying test methods recognized at the international level;
  • to ensure continuous conformance of the test laboratory to the requirements of standard LST EN ISO/IEC 17025 and other criteria specified by the accreditation body;
  • to ensure and improve high quality of provided services, meet all requirements of customers.

Accredited Activities

Products Research Division of Fire Research Centre (hereinafter FRC PRD) (till 01-02-2018 there were two separate divisions: Products Research Division and Constructions Research Division) is accredited for performance of the following fire tests in accordance with standard methods.

In addition  FRC PRD is accredited to carry out assessment of reaction to fire, fire resistance, resistance to exposure of external fire of construction products according to assessment and verification of constancy of performance (AVCoP) system 3 described in of Regulation (EU) No 305/2011 of the European Parliament and of the Council.

Unaccredited Activities

FRC PRD also performs a number of unaccredited tests which are both standard and validated non-standard in accordance with test methodology GTC/GBM prepared by FRC.

Method Selection

For the purposes of method selection the priority is given to international, regional or national standards. FRC PRD uses only the latest versions of the valid standards. FRC PRD also applies methods prepared by them provided they suit the intended application. If a client does not indicate what method should be applied, FRC PRD selects necessary methods taking into consideration that namely the selected method would ensure the reaction-to-fire parameter (characteristics) being determined in the most effective manner. The client is informed about the method selected.

Cooperation with Clients

FRC PRD cooperates with its clients or their representatives as in this way it benefits in finding out the requests of any client. To improve the quality of provided services FRC PRD asks clients to complete a Questionnaire (form KSD-107).

FRC PRD informs a client about any delay in and deviation from test activities.

FRC PRD gives a client or his representative access to the laboratory to watch the tests being performed to them.

FRC PRD tries not to perform any works, which could reduce trust in competence of FRC, their objectivity, fairness or integrity of activities; for this purpose FRC PRD:

  • informs clients on accredited tests performed;
  • uses the status of the accredited laboratory only for performance of accredited tests and presentation of results for such tests;
  • in case tests are performed not in accordance with methods specified in accreditation area or with some deviations from this method, the results of such tests are considered as those of unaccredited tests.

Sample preparation. 
Sample is preparedfrom at least 5 parts of the product. From solid homogeneous product or from a substantial component of non-homogeneous products shall be composed a representative sample of 50 g min. For a liquid applied product (e.g. paint and glue) (dried weight) or from non-substantial component of non homogeneous product shall be composed a representative sample of 10 g min. For tests shall be delivered 0,5 m2/0,5 l of each component of product.

Reaction to fire tests for products - Non-combustibility test
Specimen preparation. 
The test specimens are taken at random from the sample. The specimen is cylindrical: height (50±3) mm, diameter (45-2) mm. If is not possible to prepare a test specimen from 1 piece of material, a specimen is constructed from several horizontal layers parceled together by wire. The total number of specimens to be tested – a minimum of 5 are needed.                                                                

LST EN 13823 
Reaction to fire tests for building products - Building products excluding floorings exposed to the thermal attack by a single burning item
Specimen preparation. A test specimen, consisting of 2 vertical wings forming a right angled corner:

-       short wing (495±5) mm × (1500±5) mm
-       long wing (1000±5) mm × (1500±5) mm,

Max. thickness – 200 mm (if any reduction is needed this must not affect the fire performance of the test specimen).                                            

If the test specimen includes a vertical joint, this shall be positioned in the long wing, 200 from the corner when the specimen is put in place. If the specimen includes a horizontal joint, this shall be positioned in the long wing, 500 mm from the bottom edge. If there is an air gap in end use, this shall be reproduced in the specimen. Additional details for the mounting of the test specimen shall be in accordance with the relevant product specifications.
For test according to LST EN 13823 number of such two-wings specimens shall be from 3 to 5.                                                           

LST EN ISO 11925-2
Reaction to fire tests - Ignitability of products subjected to direct impingement of flame - Part 2: Single-flame source test
Specimen preparation.
 The specimens measurements: height (250-1) mm, width (90-1) mm, thickness up to 60 mm. If the product is normally > 60 mm thick and will need to be reduced in thickness for the test. If the product is not normally produced in a size large enough to accommodate the size of test specimen, then a special specimen has to be prepared. For test according to LST EN ISO 11925-2 shall be tested 6-12 specimens. If there are distinctly different top sides, each face may be tested (if either face may be exposed to fire), therefore quantity of specimens can increase. Also quantity of specimens increases in case of multilayered products.

Test Ordering

The client wishing fire tests to be performed at the Products Research Division of Fire Research Centre (hereinafter FRC PRD) (till 01-02-2018 there were two separate divisions: Products Research Division and Constructions Research Division), submits a completed Request (form KSD-038). A separate Request shall be completed for each product/system/construction containing a detailed description of an object presented for tests (alternatively, data about a test object is provided in appendices). FRC PRD does not carry out selection of test samples (materials, products or objects for test specimens’ preparation). The client selects and prepares/mounts test specimens himself and delivers them to FRC PRD Laboratory located at Miško str. 7, Valčiūnai village, LT-13221 Vilnius Region (in case of testing of constructions, specimens are mounted by client in the laboratory). Client is responsible that the samples presented meet the characteristics specified in the submitted documents. Together with test samples a client in some cases submits a Sample Selection Report (for example in case of certification). The client must prepare the specimens following the requirements of relevant regulations or, with the consent of the laboratory, present them in such amount from which the specialists of FRC PRD could make specimens of necessary dimensions for extra fee. A specialist of FRC PRD, who accepts specimens or material for specimens’ preparation, makes sure of suitability of an object for tests (dimensions, amount, etc.) and checks whether the client has completed a Request in a correct manner. The client may request, that tests were performed with deviations from the standard, collect remains of specimens after tests are completed, and also watch the tests being performed on his products, etc., however this has to be specified in section Additional Information of the Request.
Before tests are started, both parties sign a Contract of Work Performance. Referring to the terms and conditions of this contract a client agrees that the method offered are acceptable to him, and the Director of FRC confirms that FRC PRD can perform the test in accordance with the method selected in a proper manner. In case of the method change, the confirmation is repeated. The Advanced Payment Invoice is sent by e-mail together with the Contract of Work Performance (typical form EN, typical form RU)prepared by FRC at the address indicated in the Request.
Result Presentation

Report preparation. After tests are completed, FRC PRD prepares a Test Report where the results are presented in a precise and objective manner in a relevant form prepared for the specific test method. In case the client desired only the indicative tests to be performed or product didn’t achieve expected parameters, the Indicative Test Report (such document couldn’t be used for classification) could be prepared for him. Apart from these reports a Classification Report, Extended Application Report, Supplement to Report, Additional Report or extra original exemplar of report may be prepared for the client. If the above-mentioned document preparation is ordered not at the same time when testing was ordered, the customer submits a standard Request (form KSD-038), but in this case the graphs relating to the performance of the tests, are not filled.
Each document is prepared in two copies, one copy is given to the client and the other one is archived for a period of 25 years at the FRC. The documents are collected at FRC PRD or, upon request of the client, sent by registered mail to the address indicated in the Contract of Work Performance. Upon request of a client approved and scanned test reports (only in PDF format) may be sent by e-mail.
