MCU14/0056 Response to SARA - Consulting Report

EN 858-1:2002 (E)

8.1.6.2.6 Test specimens
Hot rolled steel test specimens 200 mm x 100 mm x 4 mm in accordance with EN ISO 1514 and/or concrete test

specimens 200 mm x 200 mm x 200 mm having a compressive strength as prescribed in 6.2.2 shatl be used, to
which the coating system is applied.

8.1.4 Chemical resistance of internal surfaces
8.1.4.1. General
Chemical resistance shall be checked by immersing three test specimens in the following four test liquids:
—— demineralised water kept at (40 + 2) °C;
— fuel oil in accordance with ISO 8217, designation ISO-F-DMA, kept at (23 + 2) °C;
— Unleaded fuel in accordance with EN 228 kept at (23 + 2) °C;
— amixture kept at (40 + 2) °C, as follows:
— 90% (m/m) demineralised water,
— 0,75 % (m/m) sodium hydroxide;
— 3,75 % (m/m) sodium orthophosphate;
~— 0,50 % (m/m) sodium silicate;
— 3,25 % (m/m) sodium carbonate;
— 1,75 % (m/m) sodium metaphosphate.

Each test shall have a duration of 1 000 h. After the immersion tests, the test specimens shall be rinsed with water,
dried in air at (20 + 3) °C for 24 h then checked for compliance with the requirements in 6.2.7.1.

8.1.4.2 Plastics materials and linings

Prepare test specimens in accordance with 8.1.2.2.

Three test specimens of each material type shall be used for each of the four immersion tests described in 8.1.4.1.
A fourth test specimen for each test shall be stored in a standard conditioning atmosphere in accordance with
EN 62, and shall serve as a control specimen.

After the tests the tensile strength, flexural strength and modulas and Izod impact resistance of every test specimen
shall be determined in accordance with EN 61, EN 63 and ISO 180 for glass reinforced piastics, and ISO 178,
ISO 180 and ISO 527-2 for polyethylene. ©

The results shall meet the requirements in 6.2.7.1.3.

8.1.4.3 Sealing materials

Sealing materials shall be tested in each of the four immersion tests described in 8.1.4.1 and the effect determined
in accordance with ISO 1817. The results shall meet the requirements in 6.2.7.1.4.

8.1.4.4 Coatings

Prepare test specimens in accordance with 8.1.3.2.6 and determine the dry film thickness, porosity and Buchholz
indentation.
