请问Standard UL 1005,    的  Soleplate Temperature Test方法,下面黄为不明处.

A scorch print was made by placing the iron, in the dry mode, on the test fixture, Figure 26.1, and energizing it until the soleplate temperature at the midpoint exceeds 204°C (400°F). The iron is then to be disconnected from the supply and the iron was placed on a sheet of white paper spread over an ironing board for sufficient time to develop a scorch pattern – normally a few seconds. After removal of the iron, darkening of the paper indicates the temperature distribution over the soleplate. The hottest point is the center of the darkest area. The coolest point is the center of the lightest area. Positive phototype paper, white tracing paper, or white blotting paper may be used as the white paper for this measurement.

For the test described in 26.2 and the Exception to 26.1 (a), the flatiron was placed with the soleplate down on a padded softwood horizontal test stand. The padding on the test stand is to consist of eight thicknesses of cloth. The cloth was bleached cheesecloth running 14 – 15 square yards per pound mass (approximately 26 – 28 square meters per kilogram mass) and having what is known in the trade as a count of 32 by 28, that is, for any square inch, 32 threads in one direction and 28 threads in the other direction (for any square centimeter, 13 threads in one direction and 11 in the other direction).
