SIST EN 12964:2002 is the Slovenian adoption of EN 12964:2001 from CEN. It specifies a laboratory method for determining the heat resistance of bonds made with lasting adhesives for leather and footwear materials. The method is intended for users who need a repeatable way to compare adhesive performance as temperature rises under load.
What does SIST EN 12964:2002 specify?
SIST EN 12964:2002 specifies one test method for measuring how bonds made with lasting adhesives behave when heated. In practice, it gives a controlled way to prepare bonded strips, heat them in a warm air cabinet, and record the temperature at which the bond fails.
The document is organized into clauses on scope, normative references, terms and definitions, principle, safety, apparatus, adhesive, test material, test pieces, procedures and evaluation, and test report. That structure takes the user from sample identification and specimen preparation through testing and result recording.
What are the key requirements of SIST EN 12964:2002?
Test principle and failure mode
SIST EN 12964:2002 measures heat resistance by bonding two strips of cotton canvas test material and heating the assembled test pieces under a constant load. The key result is the temperature at which the bond reaches cohesion (cohesive) failure while the temperature rises at 2 C/min.
In practice, this means the test is not just about whether a bond breaks, but how much heat it can withstand under a defined mechanical load and heating rate. If adhesive failure appears, the test is repeated with a thicker adhesive coating.
Specimen preparation
SIST EN 12964:2002 requires the test material to be conditioned in the standard atmosphere 23/50 and the bonding surfaces to be prepared according to the adhesive supplier's instructions, or cleaned with a hand brush if no instructions are available. The adhesive sample must be identified and prepared in accordance with EN 1066 and EN 1067, and stored at (23 ± 2) C before use.
For liquid adhesives, the standard specifies controlled application timing, drying intervals, activation of the adhesive coat, and pressing at at least (0,6 ± 0,02) MPa for 15 s. For solid lasting adhesives, it specifies cleaning the applicator, applying one coat, and forming the bond within 5 s.
Test conditions and equipment
SIST EN 12964:2002 specifies a warm air cabinet with forced ventilation, a controlled temperature range from 25 C to 300 C, and a temperature rise of 2 C/min. The cabinet must also support clamping and loading of the test pieces with weights from 1,0 kg to 5,0 kg.
This matters because the result depends on stable heating and a known load. Laboratories need equipment that can reproduce the same stress and temperature path for every test.
Result determination and reporting
SIST EN 12964:2002 requires the test to start 5 minutes after bonding is completed. If no load is specified, a preliminary test is used to find a weight that gives a separation time between 10 min and 30 min, and the final test is then run with that load.
The report records the individual and mean temperatures at separation, with the highest and lowest values ignored in the mean, plus the mode of failure. That gives a usable result for quality control and for comparing adhesive batches or formulations.
What terms does SIST EN 12964:2002 define?
- Lasting adhesive - an adhesive used to bond a shoe upper to a shoe insole during the lasting process.
- Cohesion (cohesive) failure - failure within the adhesive layer, which is the preferred failure mode in this test.
- Standard atmosphere 23/50 - the conditioning atmosphere used for the test material before specimen preparation.
- Test piece - the bonded strip assembly prepared to the specified form and dimensions for heating.
- Warm air cabinet - the forced-ventilation chamber used to heat the test pieces at a controlled rate.
- Heat activator - the device used to bring adhesive coats to the activation temperature before bonding.
Who uses SIST EN 12964:2002?
SIST EN 12964:2002 is used by adhesive manufacturers, footwear laboratories, and quality control teams working with leather and footwear materials. It is relevant where lasting adhesives are selected, checked, or compared for resistance to heat during shoe manufacture and material development.
Buyers and quality managers use it when they need test data that can be repeated by another laboratory. Test technicians use it to prepare specimens, run the heating test, and report the separation temperature in a standard form.
What changed in SIST EN 12964:2002 from the previous edition?
SIST EN 12964:2002 is the Slovenian standard identical to EN 12964:2001.
Which standards are used with SIST EN 12964:2002?
- EN 923 - provides the general adhesive terms and definitions used in the document, including cohesive failure.
- EN 1066 - covers sampling of adhesives.
- EN 1067 - covers examination and preparation of samples for testing.
- ISO 554 - provides the standard atmospheres for conditioning and testing, used here for the test material conditioning step.
What does the SIST EN 12964:2002 document contain?
SIST EN 12964:2002 contains the full test procedure, from apparatus requirements to the final report. It includes the test-piece form and dimensions in Figure 1, and the arrangement for applying solid lasting adhesives in Figure 2.
It also gives the required conditioning, cutting, bonding, activation, pressing, heating, loading, and evaluation steps. The reporting clause lists the adhesive identification, test material identification, bonding procedure, applicator, test type, results, failure mode, deviations, and test date.
