EN 15998-2020 pdf download.Glass in building – Safety in case of fire, fire resistance – Glass testing methodology for the purpose of classification.
5.1 General
5.1.1 General remark
The sampling of glass products for incorporation into virtual assemblies for fire resistance testing depends on the reason why the fire resistance test Is being undertaken.
5.1.2 Classification of a glass product
When a fire resistance test is part of the type testing (TT) of the glass product for the characteristic “Safety in case of fire — Resistance to fire (for glass for use in a glazed assembly intended specifically for fire resistance)” then the responsibility for the sampling is specified in the applicable product standard. Details of the sampling are given in .Z.
5.1.3 Market application testing
When a fire resistance test is conducted for market application, the details of the sampling are given In Annex B.
5.2 For determination of fire resistance as a product characteristic for a glass
5.2.1 Classification of a glass product
The appropriate standard concerning evaluation of conformity, covering the characteristic ‘Safety in case of fire — Resistance to fire (for glass for use in a glazed assembly intended specifically for fire resistance)” requires the following tasks:
— initial examination of the factory production control system;
— initial Inspection of the factory;
— overall control oftheTT;
— ongoing surveillance of the factory.
The control of the TT includes the selection of samples for the testing. The rules are as follows:
a) for type testing (TT) the samples shall be representative of the product taken from any plant and/or line or from stock, or a sample declared to be a prototype;
b) all samples to be used for TT testing purposes shall be accompanied with suitable documentation and/or marking to allow subsequent verification that the producer has fulfilled their obligations;
c) this documentation shall include at least the following information:
1) manufacturer and manufacturing plant;
2) place of sampling;
3) when applicable, stock or batch number (from which the samples have been taken to ensure traceability);
4) number of samples;
5) identification of the construction product in accordance with the technical specification;
6) marking of the product by the manufacturer;
7) marking of the samples by the sampler;
8) where necessary, properties to be tested;
9) place and date;
10) signatures;
11) registration number of the Notified Body.
NOTE The role of the notified body is defined in Annex ZA of the appropriate product standard.
During the sampling, additional samples may be requested to be taken for internal product control testing as described in the factory production control (FPC) schemes of the product standards. This is normally detailed in Annex.A of the product standard. This action should be executed and recorded as part of the technical file.
Prototype samples to be used for testing purposes should be suitably documented to allow subsequent verification that the actual product manufactured on the (future) production line is the same as the prototype.
When sampling is done prior to a number of tests, then the sampled products should be indelibly marked by the sampling body and stored in a manner ensuring that the product does not deteriorate.
5.2.2 Market application testing
Details on sampling are given in Annex B.
5.3 Non-sampled test results
5.3.1 General
In the event that sampling is done under the responsibility of the manufacturer, there are consequences regarding the validity of the test report. There are two possibilities:
a) Case A: Fire resistance test conducted according to one of the standards listed in 4.3. glass product sampled by the manufacturer who demonstrates the traceability as below:
1) manufacturer and/or manufacturing plant;
2) stock or batch number, shipping documents;
3) identification of the construction product in accordance with the technical specification;
b) Case B: Fire resistance test conducted according to one of the standards listed in 4.3.. glass product sampled under the responsibility of the manufacturer who cannot demonstrate complete traceability.
5.3.2 ClassifIcation of a glass product
Neither Case A nor Case B can be accepted as a TT.
NOTE Pre-existing test data are appropriate for market application testing if done to the relevant product standard(s even when sampled by the manufacturer and without full traceability.
5.3.3 Market application
The influence of test results from products sampled under the responsibility of the manufacturer is
given in Aiinexb.
