How to do if the solid alcohol for fuel purpose is requested for testing according to Thai Industrial Standard 950-2547 (TIS 950-2547).
The submission of the solid alcohol for fuel purpose at the Department of Science Service (DSS) can be classified into 2 cases:
- Case #1: The manufacturer needs the test result for requesting the TIS mark permission from Thai Industrial Standard Institute (TISI).
- Case #2: The manufacturer already has the TIS mark permission, but TISI needs to randomly check the quality of the product.
Both cases require the sample preparation as follow:
- Two sets of the sample (at least 500 grams per a set of sample; at least 2 containers per a set of sample) are required.
- The sample must be in the completely closed container to protect the evaporation of the sample.
- The label on the sample container indicates the title, mark, manufacturing date, and net weight of the sample.
