4.1 Pre-treatment
Products to be tested shall be intactly assembled and deliverable finished products. The product
and its components shall be assembled and / or configured in accordance with the instructions
provided. Unless otherwise stated, the tests shall be performed in the configuration that is least
conducive to the mechanical properties. If assembly or configuration instructions are not
provided, then, the assembly or fitting-together method shall be recorded in the test report.
Before the tests, fittings shall be tightened, and shall not be tightened again during the test when
there are no special requirements in the manufacturer's instructions. If changes in product
configuration are required to simulate the worst-case scenario, then, this shall be recorded in
the test report.
Unless otherwise specified by the manufacturer, before the tests, the unit shall be placed without
load for at least 24 hours under indoor environmental conditions.
The test shall be carried out on the test ground. The unit shall be leveled, and the leveling device
shall be set in the middle position, but it shall not be more than 13 mm from the fully closed
position.
The units used for installation on buildings shall only be tested in accordance with 6.7.
