4.5 The thermocouples used to measure the temperatures on the face of the calibration column are to be No. 28 gauge, Type K inconel sheathed thermocouples having a time
constant of 0.5 s or less. The thermocouple junction is to be located 1/4 in (6.3 mm) from the face of the calibration column.
component elements of the steel column. Figure 5.1 shows typical locations of thermocouples on wide flange and tubular steel columns. The thermocouples are to be fabricated from
minimum 0.032 in (0.8 mm) diameter (No. 20 B & S gauge) chromel-alumel wires or equivalent having a time constant of 2 s or less.

   8.4 The test sample is to be conditioned in compliance with the requirements of 5.5 prior to the test.
8.4 试验前试件条件应满足5.5要求。  
8.5 在调节后(试件满足要求),实验前,试件要符合附录A所述:经过选择的模拟的环境,这些暴露条件是防护材料在其特定用途中预期将要遭受的.除此之外的其他环境暴露可以依据附录A进行模拟.
  4、露地越冬:朱顶红在长江以南地区可以露地越冬,处理方法轻便,于秋末冬初将叶片剪除,鳞球上壅土或覆以稻草。露地越冬的植株翌年长势兴旺,花苞茁壮,但在多雨雪的地区和日照透风条件差的状况下,轻易爆发腐败。紫斑牡丹其实也是牡丹花中的一种,而且比拟名贵,因花瓣基部有一个清晰的色斑而得名,具有很高的观赏价值。      其它由买方或制造厂认为必要的检验与测试;     执行器防火罩联系:13818263959;陈经理;
