Therefore, it is necessary to develop a measuring cable or The approved method for the amount of acid gas released when the material of the optical cable is burned. GB/T 17650 provides a method to determine the amount of acid gas Or reach an agreement on the limit value of the optical cable specification. Since this test is not carried out on the entire cable or optical cable sample, the evaluation of the degree of harmfulness It is also necessary to consider the actual volume of the material that constitutes the cable or fiber optic cable. The recommended values of pH and conductivity given in this document can only be regarded as an indication, because the relationship between corrosion and these two parameters is not Must be able to include all materials. The purpose of GB/T 17650 is to establish a test method standard for gas released when materials taken from different cables or optical cables burn. It consists of the following 3 parts. ---Part 1.Determination of the total amount of halogen acid gas. The purpose is to establish a combustion release suitable for materials taken from different cables or optical cables. Test method for the total amount of halogen acid gas in the exhaust gas; ---Part 2.Determination of acidity (measured by pH) and conductivity. The purpose is to establish Test methods for acidity (measured by pH) and electrical conductivity of gases released when materials are burned; ---Part 3.Determination of low-level halogen by ion chromatography (planned). The purpose is to establish suitable for different cables or optical cables The test method for the release of low-content halogen in the gas when the material burns. The test equipment in Part 1 and Part 2 of this document is basically the same, but it should be noted that the test procedures are quite different. When the material taken from the cable or optical cable burns Test method for released gas Part 1.Determination of the total amount of halogen acid gas1 ScopeThis document specifies the measurement of halogenated polymer-based mixtures and halogen-containing additive mixtures taken from the structure of cables or optical cables. Equipment and procedures for the total amount of halogen acid gas released during combustion except for hydrofluoric acid. Note 1.This test method cannot be used to determine the fluorine content, see IEC 60684-2 for the test method for fluorine content. Note 2.This test method can be used to test the materials used in the production of cables or optical cables, but it is not appropriate to declare the performance of cables or optical cables based on such a test. Note 3.The relevant cable or optical cable standard should specify which components in the cable or optical cable should be tested. Note 4.For this document, "cable" refers to all insulated metal conductor cables that transmit energy or signals. The method specified in this document is applicable to the determination of individual components in a cable or optical cable, and can determine the individual components of the cable or optical cable. Whether the components meet the requirements. Note 5.Under the premise of agreement between the supplier and the buyer, the method given in this document can be used to determine the halogen acid gas content of the cable or the overall mixed material of the optical cable. but The use of this method is not suitable to determine the eligibility of the cable or optical cable performance. Appendix A gives relevant information about this test method. Due to the measurement accuracy, it is not advisable to give the test value in the report for materials with a halogen acid gas content of less than 5mg/g.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text. Among them, dated quotations Only the version corresponding to that date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to This document.

The method is. acidify the sodium hydroxide solution with nitric acid and add a certain volume of 0.1mol/L silver nitrate ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 17650.1-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 17650.1-2021_English as soon as possible, and keep you informed of the progress.
