Coaxial Communication Cables Part 1-205. Environmental Test Methods
Solvent and contamination test
1 Scope
This part of GB/T 17737 applies to coaxial communication cables. It specifies the test method for determining the solvent resistance of the cable and its ability to contaminate the liquid.
2 Normative references
The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article
Pieces. For undated references, the latest version (including all amendments) applies to this document.

3 Terms and definitions
The terms and definitions defined by IEC 61196-1 apply to this document.
4 Overview
Plastics show different characteristics when they come into contact with solvents and contaminated liquids, even if these solvents and contaminated liquids have similar components.
Belong to the same category.
Therefore, the cable is usually not considered to be resistant to solvents or contaminated liquids. It can only be regarded as resistant to such solvents or contaminated liquids after passing the test.
5 test liquid
5.1 General rules
The liquids that may have a detrimental effect on the communication cable are given in the following three tables, and the temperatures at which the tests are performed are given.
The test liquids should be specified in the relevant detailed specifications and sub-regulations and should be selected from Table 1, Table 2 and Table 3 as a priority.
Other test liquids, test temperatures, and test times may be agreed upon by both parties.
5.2 test liquid table
Table 1 Fuels, Lubricants, Hydraulic Oil, and Antifreeze
No. Test Liquid Test Temperature
a) Mixture of toluene (aromatic) 30% and isoctan (aliphatic isooctane) 70% (by volume) 40°C ± 2°C
b)
Wide-fraction aviation turbine fuel
Solutions 1 and 2 are typical mixtures that can have the worst effect on the cable
70°C±2°C
