Dear Chaiwit,
This is the important report and suggestion from Mr. Yamaguch.
Don’t use the No.10 Performance Machine for RT50 for time being. I need to discuss with you about following report sent by Mr. Yamaguch after your training at Bangplee finished
Content….
He tested three samples which have passed in No.10 Machine by HOT BOX. That setting condition of temperature is 3℃lower than normal test. As a result, 3 test samples were passed test.
■By the following reasons, No10 performance machine should be prohibited to use for RT 50 FD test anyway. No.10M/C is used another model except RT50.
1) Dispersion is seen in a performance curve of the ON turn nearby. (There is dispersion by a product. Cf. attached performance test graph)
2) RT50 is easy to occur dispersion of the performance because
i. a quantity of oil in standard is severe,
ii. set temperature range is severe
3) Need to set a testing temperature of RT50 down for normal in No.10M/C.
4) In No.10M/C , set temperature is displayed rather high in comparison with other performance test M/C.
Due to above, he request us to use No.10 M/C as testing equipment except RT50.
■He will make Master for No.10 M/C if we have request that we want to use No.10 for RT50.
Best regards,
Kitak
