Temperature rise as K? & ANSI/UL 875

[Jakelian]

Dear users, I have two questions:

1. In several places of the heating sections of Euro (EN) standards, there are several tables showing temperature rise as K. For example: "During normal operation, the temperature rise of the applience's walls shall not exceed 140 K". What does 140 K mean??

2. Why it says ANSI/UL 875 - Electric Dry Bath Heaters for this standard? I mean, ANSI and UL at the same time? WHat does ANSI have to do with that?

Thanks!
