(Test No. 1-i) Sensory verification of Odour/Smell
Test Specification(s)/Regulation(s): Regulation (EC) No. 1935/2004 & Council of Europe Resolution ResAP (2004) 5 on silicones to be used for food contact applications;
Test method adopted: DIN 10955:2004;
Simulant(s) used: Distilled Water;
Test Condition(s): 100°C or reflux for 4 hours.
| COMPONENT NO. | TEST PARAMETER | RESULT (GRADE) | COMPLIANCE REQUIREMENT/LIMIT MAX | CONCLUSION (PASS/FAIL) |
| A | Rating | 1 | Less than 2.5 | Pass |
| Note:
(Intermediate grades are allowed) 0 = no perceptible difference in odour; 1 = just perceptible difference in odour (still difficult to define); 2 = slight difference in odour; 3 = marked difference in odour; 4 = strong difference in odour. |
