1 Scope

This part of GB/T 39560 specifies a boiling water extraction method whose purpose is to treat colorless and colored anticorrosive plating on metal samples: The hexavalent chromium in the layer is qualitatively determined: Due to its high activity, the content of hexavalent chromium in the anticorrosive coating will change significantly with time and storage conditions: Because of the Storage conditions are often unknown or unavailable, so the process can only be determined based on the hexavalent chromium content detected in the coating during the test: Determine its existence: When testing the newly plated samples, a waiting time of at least 5d is required (after the plating process is completed) to ensure that the plating has been After stable: The oxidation of trivalent chromium to hexavalent chromium may occur during the waiting period: The existence of hexavalent chromium is determined by the mass of hexavalent chromium contained in the unit surface area of the coating, and its unit is expressed in micrograms per square centimeter (μg/cm2) Show: This method is preferred because it is often difficult to accurately measure the quality of the anti-corrosion coating after the product is produced: From the plating technology From a point of view, the changing trend of the entire industry is to use chemicals that do not contain hexavalent chromium, that is, there is little or no hexavalent chromium: Do not use traditional chemical substances containing hexavalent chromium, that is, the content of hexavalent chromium is significant and can be reliably detected: Considering industry changes To determine whether the presence or absence of hexavalent chromium is sufficient to meet the testing purpose of regulatory compliance: In this process, if the detection of hexavalent chromium in the sample is lower than the LOQ (Limit of Quantification) of 0:10μg/cm2, it can be considered as the hexavalent chromium of the sample: Chromium is negative: Since hexavalent chromium cannot be evenly distributed in the coating even in the same batch of samples, the 0:10μg/cm2~ The "grey area" between 0:13μg/cm2 is determined as "inconclusive" to reduce the inconsistent results due to inevitable changes in the coating: fruit: In this case, additional tests may be required to confirm the presence of hexavalent chromium: When the content of hexavalent chromium is higher than At 0:13μg/cm2, the sample is considered to be positive, that is, there is hexavalent chromium in the coating:
