Scope of accreditation

FIRE RESEARCH CENTRE PRODUCTS RESEARCH DIVISION is accredited to perform tests according these test methods:

Flexible scope of accreditation confirmed on 15-04-2026

LST EN ISO 1716
Reaction to fire tests for products - Determination of the gross heat of combustion (calorific value)
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.

LST EN ISO 1182
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.

LST EN ISO 9239-1
Reaction to fire tests for floorings – Part 1: Determination of the burning behaviour using a radiant heat source
Specimen preparation. The test specimen shall be representative of the flooring in its end use. The specimens measurements:  (1050±5) mm × (230 ± 5) mm, 6 specimens: three in one direction (e.g. production direction) and three in a direction perpendicular to the first direction. The specimen shall be mounted on a substrate that simulates the actual floor (see EN 13238). Additional information about floorings mounting is here.

LST EN 60332-1-2
Tests on electric and optical fibre cables under fire conditions. Part 1-2: Test for vertical flame propagation for a single insulated wire or cable. Procedure for 1 kW pre-mixed flame
Specimen preparation. Specimen‘s length shall be (600±25) mm. 3 equal specimens shall be prepared for the test.

LST EN 1021-1
Furniture – Assessment of the ignitability of upholstered furniture – Part 1: Ignition source smouldering cigarette
Specimen preparation. The outer cover size needed for each test shall be 800⁺¹⁰mm ´ 650⁺¹⁰mm (the cover should be cut to these dimensions after soaking procedure). The long dimensions shall be cut parallel to the machine direction. Two pieces of filling are necessary for each test, with the following dimensions:
one piece (450±5) mm x (300±5) mm x (75±2) mm thick;
one piece (450±5) mm x (150±5) mm x (75±2) mm thick.

LST CEN/TS 1187
Test methods for external fire exposure to roofs. 1 test method
Specimen preparation. For tests of one type roof construction is necessary to prepare 4 specimens with different joints. Additional information is only in Lithuanian.
