Annex B

Test Procedures

B.1

IR (Infra-Red Spectroscopy)

According to the instruction manual of the equipment used. See also EOTA TR 024, Annex C for details when used as identification method (Fingerprint).

B.2

Thermo-analytical methods

B.2.1

Thermo-gravimetric Analysis (TGA)

See EOTA TR 024

B.2.2Differential Thermo Calorimetry (DTA)

B.3

Content of non-volatile components

Test according to EN ISO 3251.

The value reported as a declared value for identification shall be the mean value of at least three specimens.

B.4

Weight loss on heating (ash content)

Test according to EN ISO 3451-1, subject to the following provisions: As weight loss on heating is a characteristic of a material, protective foils or coatings should be removed if at all possible. When the product is tested with a protective foil or coating this should be recorded to ensure consistency with future tests.

NOTEThe standard was written for plastics but other materials can also be tested following the principles of the standard.

The value reported as a declared value for identification shall be the mean value of at least three specimens.

B.5

Mechanical properties

B.5.1

Compressive strength

B.5.1.1

Mortars (cement based)

Test according to EN 1015-11.

The strength at 3, 7 or 28 days may be determined dependent on whether high early strength or normal cement is used.  

B.5.1.2

Plaster (gypsum based)

Test according to EN 1015-11

This method may be applied to gypsum based products subject to the product being tested after 24 hours, fully saturated, and after oven drying at 30 to 35ºC to constant weight.

B.5.2

Tensile strength

B.5.2.1

Rubber

Test according to ISO 37 or EN ISO 527-2.

B.5.3

Hardness  of sealants (cured)

Test according to ISO 7619 -1 or ISO 7619-2. The ETA shall specify the method used

B.5.4

Tear strength

B.5.4.1

Fabrics

Test according to EN ISO 13934-1

B.5.4.2

Seam

Test according to EN ISO 13935-1 or EN ISO 13935-2. The ETA shall specify the method used
