This international standard is for the revision of [3R.5119R7] core chain liquid. Compared with G3/T8184-1987, this standard mainly has the following changes: GH/T 8184-2004
Xuan original "hardness test method of natural layer" is changed to "residual preparation method". The detection of this layer is more exploratory: the hardness test of heat rate is unified, and the two brands in the standard, namely the production of embedded armor core chain, the evaluation of the performance and technical performance of the core chain, are more in line with the various requirements of production credit,
In the original electric analysis of the electrolytic solution of the micro-point separation, so that the analysis of the shore is more accurate,
