General1 ScopeThis section GB/T 5158 specifies the determination of General reduction in the oxygen content of the metal powder, gives a correct interpretation of the results obtained Suggest. Test methods in this section are generally available for all metals, alloys, tungsten carbide powder, and mixtures thereof. Under test conditions the powder Composition should be no volatile substances, organic binder or lubricant should be removed. However, some limited stored depends on the nature of the analysis of the metal, which is defined in Chapter 4.2 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document.

Powder should be tested to receive state. Metal powders are usually readily with air and moisture response of the material, therefore, the subject for which the sample Goods handling and storage should pay special attention. Remove the sample to be analyzed immediately.4 meaning the results of the test method used to obtain the4.1 hydrogen as a reducing agent 4.1.1 when tested under specified test temperature, only the following metal oxides may be all hydrogen reduction. Fe, Ni, Co, Cu, Ag, Sn, Pb, W, Mo, Re. All other common oxides are not reduced by hydrogen, in particular, Al2O3, SiO2, ZrO2, and other alkali metals, alkaline earth metals And most rare earth oxides. Chromium, manganese, titanium and vanadium oxide can be partially restored. 4.1.2 Other reactions also occur during the restore process and composition of the powder. a) hydrocarbons and water vapor and other gases adsorbed on the sample powder in the presence of the release during heating. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 5158.1-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 5158.1-2011_English as soon as possible, and keep you informed of the progress.
