德國標準 DIN 4102-2, class A1/A2 建材阻燃測試

Description

Net prices excl. VAT

Pos. 1  Test following DIN 4102-1 (A1/A2), Non-combustibility, in the A-oven

For the test at least 6 specimens per material are required with the following dimensions

(L) 40 mm x (W) 40 mm x (H) 50 mm (tolerance +/-1 mm)

If the specimens have to be built by use of single layers, the layers have to be cut to 40 x 50 mm (L x H). The layers combined have to form a specimen being 40 mm thick (width).

In case of construction materials with different characteristics longitudinal and perpendicular to direction of production, half of the specimens have to be taken from each direction.

Construction materials fulfill the requirements for classification to Class A1 if,…

- the oven test is passed and

- the requirements for class A2 are fulfilled; it may be resigned to conduct the test in parts or completely, if the fulfilment of these requirements can be assessed without any doubt.  

For a complete compliance with the classification in addition the tests on class A2 in the ?Brandschacht“ (B1-testing apparatus with higher requirements) and in the B2-cabinet (small flame test) would have to be conducted. Maybe the smoke densitiy tests for construction materials according class A have to be conducted as well – if required. If you are in need of the smoke density tests as well, we would appreciate to be informed accordingly for sending an additional offer.

Pos. 2   DIN 4102 part 1, class B1

For the test according to DIN 4102 part 1, class B1 we need in total 16 samples with the following dimensions:

1000 mm long, 190 mm wide, original thickness.

xxx EUR

per product/direction

If the test result is not obvious with the first test, the standard asks for 2 additional tests per direction, so in total 3 tests per direction. Each additional test:

xxx EUR

per product/direction

Please note:

Materials with an orientation, e.g. foils, leathers, textiles, have to be examined in each direction (warp and weft) with 16 samples along and
16 samples transverse to production direction. Please mark production direction.

Costs increase accordingly.

For the tests you can decide on your own, if you want only one test per direction or the three tests per direction according to the standard.

Please be aware, that the test with freely suspended material is not valid for constructions with this material in combination with other layers (e.g. adhesive, wood, ....).  The burning behavior of panels in end use condition have to be tested separately.

 
Pos. 3   DIN 4102 part 1, class B2 (mandatory pre-test for B1-test)

For the test according to DIN 4102 part 1, class B2 (mandatory pre-test for B1-test) we need in total 12 samples per product with the following dimensions:

6 samples with 190 mm long, 90 mm wide, original thickness. E.g. 1. Edge flaming:

xxx EUR

per product/direction

The following position depends on the used material (has to be tested if critical):

6 samples with 230 mm long, 90 mm wide, original thickness. E.g.2. Surface flaming:

xxx EUR

per product/direction

 
Materials with an orientation, e.g. foils, leathers, textiles, have to be examined in each direction (e.g. warp and weft) with 12 samples along and 12 samples transverse to production direction. Please mark production direction.

If there are different thicknesses we need 12 samples of the material with minimum thickness and 12 samples of maximum thickness.

Further, if the material is produced in different colours, the lightest and the darkest colour as well as the deepest red shade has to be tested for the full range of colours of a product.

Further tests may be required if the material has different surfaces on front and back side. In this case testing of both sides is required.

Costs increase accordingly.

Climatization: before B2 at least 14 days in standard atmosphere DIN 50014-23/50-2

Sometimes it is only possible to determine the exact scope of testing for various products after knowing all of the product variants (colors, weight per unit area).

The above mentioned prices include a report in English language per complete test and material.

When we see that the product will not fulfill the requirements then we will stop the test and inform you.
