Flexible cellular polymeric materials - Determination of stress-strain characteristics in compression - Part 2: High-density materials - Amendment 1 (ISO 3386-2:1997/Amd 1:2010)

This part of IS0 3386 specifies a method for the determination of the compression stress-strain characteristics of flexible cellular polymeric materials of density greater than 250 kg/m3. The compression stress-strain characteristic is a measure of the load-bearing properties of the material, though not necessarily of its capacity to sustain a long-term load. The compression stress-strain characteristic differs from the indentation hardness characteristics (as determined in accordance with IS0 2439) which are known to be influenced by the thickness and the tensile properties of the flexible cellular material under test, the shape of the compression piate, and the shape and size of the test piece. IS0 3386-l specifies a method for low-density flexible materials, and differs from Part 2 in the following ways:
Part 1 is concerned with materials of density up to 250 kg/m’, whilst Part 2 is mainly concerned with materials of density above 250 kg/m3; compression stress values have been deleted from Part 2; Part 2 does not allow the use of a cylindrical test piece. This part of IS0 3386 is a general method for testing denser flexible cellular materials (i.e. expanded cellular rubbers), measurements being made on one of more points on the steeply rising part of the stress-strain curve. The shape factor of the test piece is important and comparative test results can only be obtained on test pieces having the same shape factor. NOTE 1 For comparison purposes, the method may be used for material of 150 kg/m3 density or greater.

Penjeni polimerni materiali - Mehke pene - Določanje diagrama napetost/raztezek - 2. del: Materiali z visoko gostoto - Dopolnilo 1 (ISO 3386-2:1997/Amd 1:2010)

This part 3386 določa metodo za določanje diagrama napetost/raztezek penjenih polimernih materialov z gostoto, večjo od 250 kg/m3. Diagram napetost/raztezek je mera za nosilnostne lastnosti materiala, čeprav ne nujno za njegovo sposobnost vzdržati dolgotrajno obremenitev. Diagram napetost/raztezek se razlikuje od trdnostih lastnosti vtiskovanja (kot se določajo v skladu z IS0 2439), na katere, kakor je znano, vplivajo debelina in natezne lastnosti preskušanega penjenega materiala, oblika plošče za stiskanje ter oblike in velikosti preskušanca. IS0 3386-l določa metodo za penjene materiale z nizko gostoto in se razlikuje od 2. dela po naslednjem:
1. del obravnava materiale z gostoto do 250 kg/m’, medtem ko 2. del obravnava predvsem materiale z gostoto nad 250 kg/m3; iz 2. dela so bile izbrisane vrednosti obremenitev pri stisljivosti; 2. del ne dovoljuje uporabe valjastih preskušancev. Ta del ISO 3386 je splošna metoda za preskušanje gostejših penjenih materialov (tj. ekspandiranih penjenih gum), merjenje pa poteka na eni ali več točkah na strmo vzpenjajočem se delu krivulje napetost/raztezek. Faktor oblike preskušanca je pomemben, zato so primerljivi rezultati preskušanja pridobljeni le na preskušancih z enakim faktorjem oblike. OPOMBA 1: Za primerjavo se metoda lahko uporablja pri materialu z gostoto 150 kg/m3 ali več.
