Minimum Ash Fusion Temperature
Softening (H=W Reducing Atmosphere)

Russian translation:H=W
Explanation:
Это обозначения высоты и ширины конуса, сделанного из золы, используемого для выполнения одного из стандартных испытаний. Вот выдержка, которая все объясняет:

The ash fusion temperature under oxidizing and reducing conditionsis another important test that provides very practical information. In this test (ASTM Standard D-1857), a sample of the material is ashed. The mineral ash is then pressed into a cone shape and placed in a muffle furnace on a tilted ceramic plate. The furnace temperature is ramped
up at a set rate while the cone is observed. Four temperatures are noted:

Initial deformation temperature (IDT), where the tip of the cone just shows
deformation
Softening temperature(ST), where the cone is slumped such that the height and width of the ash mass are equal
Hemispherical temperature(HT), where the mass is fluid but, due to surface tension, has a hemispherical shape with the height equal to one-half of the width
(Из книги COMBUSTION AND INCINERATION PROCESSES by Walter R. Niessen. 3rd Ed

)Испытание может проводиться в восстановительной атмосфере. Отсюда Reducing atmosphere. Может использоваться и окислительная

H(ydrogen) = W(ater)


Explanation:
водород и влага (водяной пар)

Их соотношение определяет характер газовой среды (окислительный или восстановительный) в печи, который, в свою очередь, влияет на температуру плавления золы
