Cup#1 Load, g: 100 °C: 61 °C: 61.5
Trial #1: 46
Trial #2: 48 Softening Point to Report, °C: 61.3
Trial #3: 47
AVERAGE: 47 1. Heat sample no more than 110°C above expected softening point within 2 hr max.
Report to the nearest whole unit the average of 3 penetrations 2. Pour sample into heated rings. Total time from this point not to exceed 240 min.
whose values do not differ by more than the following: 3. Cool, at ambient, for 30min. Trim excess w/heated spatula.
Pen range: 0-49 50-149 4. Assemble apparatus (w/steel balls at bottom); fill w/water to 105mm depth; return to refrig
Max difference between 2 4 or ice bath for 15 min
highest & lowest penetration result 5. Apply heat at 5°C/min. After first 3min, max. variation is +/-0.5°C
6. If the difference between the two temperatures exceeds 1°C (2°F), repeat the test.
7. When using a 15C or 15F thermometer (low temp range), then report to nearest 0.2°C (0.5°F)
