Extraction Data Test Results
Test Name: Determination of Amount of Extractives
Method : With reference to US FDA 21 CFR 177.2600
| EXTRACTANTS | TEST CONDITION | AMOUNT OF EXTRACTIVES (MG/INCH²) 1 | Acceptable Limit (mg/inch²) | CONCLUSION |
| Distilled Water | 70º C for 2 hour | <1 | <20 | Pass |
| n-Hexane | 70º C for 2 hours | <4 | <175 | Pass |
Conclusion: When tested as specified, the submitted sample complies with the specifications for the amount of extractives requirement for rubber articles intended for repeated use in contact with aqueous and fatty foods as stated in FDA 21 CFR 177.2600
