Volvo VCS-1027, 14標準介紹

Volvo VCS-1027, 14英文簡介

This test procedure defines an accelerated corrosion test method, to be used in assessing the corrosion resistance of metallic materials, with or without corrosion protection, where there is a significant influence of chloride ions (e.g.; sodium chloride) from a marine source or road de-icing salt. This test is cyclic in nature, i.e.; test specimens are exposed to changing climates over time.

Test specimens are placed in an enclosed chamber and exposed to a changing climate that comprises of a 1 week duration main test cycle, which is composed of 2 x 12 hour sub-cycles, one with controlled humidity cycling (sub-cycle 1) and the other including salt application (sub-cycle 2). Details as follows:

Sub-cycle 1

Step 1; 4.0 hours exposure to a constant climate of 95%RH at +35C. Step 2; exposure to a changing climate during which the humidity is reduced to 50%RH and the temperature increased to +45C, linearly, over a period of 2.0 hours. Step 3; 4.0 hours exposure to a constant climate of 50%RH at +45C. Step 4; exposure to a changing climate during which the humidity is increased to 95%RH and the temperature reduced to +35C, linearly, over a period of 2.0 hours.

Sub-cycle 2

On Mondays & Fridays sub-cycle 1 is replaced by the following;

Step 1; Spray with salt solution (from above) for 15 minutes. Step 2; 1 hour & 45 minutes exposure to a constant climate of 95-99%RH at +35C (test specimens to remain wet throughout). Steps 1 & 2 are then repeated in sequence twice to give a total period of 6.0 hours. Step 3; drying in a changing climate during which the humidity is reduced to 50%RH and the temperature increased to +45C, linearly, over a period of 2.0 hours. Step 4; 2.0 hours exposure to a constant climate of 50%RH at +45C. Step 5; exposure to a changing climate during which the humidity is increased to 95%RH and the temperature reduced to +35C, linearly, over a period of 2.0 hours.

Alternative sub-cycle 2

As an alternative to sub-cycle 2, samples may be completely immersed in salt solution instead of sprayed with salt solution, in which case step 1 of the above sub-cycle 2 is replaced with the following step;

Step 1; Immerse samples in salt solution for 15 minutes.

STD1027, 14 is a Volvo test standard.
