ASTM D1833 Standard Test Method for Odor of Petroleum Wax
5. Apparatus
5.1 Scraper - A knife, vegetable scraper, or other sharp instrument that can be cleaned easily. Mechanical devices that produce thin shavings from wax, such as vegetable shredders or chisel-shaped bits, may be used.
5.2 Paper - Odor-free paper or glassine for receiving the wax shavings.
5.3 Bottles, 8-oz (250-mL) wide-mouth, with caps (for alternative procedure only).
6. Test Panel
6.1 The odor test panel should consist of at least five people.
6.2 In selecting panel members for wax odor testing, the important factors to be considered are (1) agreement with the "true" rating, and (2) individual consistency. A method which may be used for checking these factors is given in the Appendix.
NOTE 1 - Any members with respiratory infection should be omitted since sensitivity may be impaired.
7. Sample and Test Specimen
7.1 The sample shall consist of a block of wax at room temperature, from which at least 100 g of shavings may be obtained.
7.2 The test specimen for evaluation by each panel member shall consist of approximately 10 g of wax in thin shavings obtained from the sample.
