19.2 Replacement:
Appliances are operated under the conditions specified in Clause 11 but supplied at 0,94
times rated voltage. However, appliances in which the heating element is part of the
secondary circuit of a transformer are operated continuously for 30 min unless they
incorporate a biased-off switch, in which case they are operated for 5 min. Firelighters are
operated for 2 h without adding fuel.
Paint strippers incorporating integral scrapers are held horizontally in a clamp over the entire
length of the handle. A force of 70 N is exerted on the scraper edge in the direction
corresponding to normal use.
19.3 Replacement:
The test of 19.2 is repeated but with the appliance supplied at 1,06 times rated voltage
按照标准，只给出19.2，19.3的电压要求

"..conditions specified in clause 11..." this mean tested as cl.11 except the test voltage and duration which stated in this cluase.作者: syyhiw 时间: 2012-1-2 10:06
不知道
要不要靠近测试角
热风枪的温度很高
很可能导致木板温度超过150K
