1. Basis for combustion.
1. Progressive combustion of combustibles.
In order to comply with EU standards, the following various actions are referred to as progressive combustion of combustibles.
a) Any test used to demonstrate combustion escalation is not safe to be carried out on an ongoing basis and decisive extinguishing is a must.
b) Any combustion test to the extent of high consumption.
c) Any test specimen with extreme burning, i.e. the edges of the upper and lower wheels, or the sides, or the entire thickness of the entire wheel, is completely lost in the test.
d) Any burn test that lasts more than one hour.
e) Any test that has evidence of sufficient combustion after the final verification of the zui.
Annotation practice has shown that there is a clear distinction between materials under the influence of combustion, and materials that burn are not easy to spread (non-progressive combustion) and materials that are prone to spread and spread (progressive combustion).
2. Combustion of smoking combustibles.
In order to comply with EU standards, the following actions are referred to as the combustion of smoking combustibles.
a) Any test used to demonstrate oxidative combustion upgrades is unsafe to be carried out on an ongoing basis and decisive extinguishing is a must.
b) Any burning test that is essentially burned.
c) Any test in which the front end of the flame reaches the lower edge, or to the side, or penetrates the entire thickness and causes loss.
d) Any test in which combustion lasts for more than 120 seconds after removing the gas line.
2. Principles. The theme is to study how decorative material components can be a combustible source of gas flames. The placement of the components stylizes the seat and backrest (the connection between the seat and the armrests), as in the case of a typical chair. The flammability of a component depends on the material of the ignition material, such as a gas flame equivalent to a burning match.
The test method measures the flammability of all components of the material, such as the outer covering, the inner covering, the filling, etc., just like the composition of a test bench. Test results do not apply to the general behavior of all individual ingredients.

Anonymous users2024-01-22Specifically, you can look at the national standard, dear.
The color matching of the living room should be based on the color of the furniture, and the walls, floors, curtains, bedspreads, sofa covers, tablecloths, etc. should be coordinated around the main color. For example, the wall should be matched with light gray, tender green or milky white when using light-colored furniture; For dark furniture, in order to set off the furniture and brighten the room, the wall should also be matched with light rather than bright colors. What color to choose, when designing, it should also be considered with the owner's hobbies and personality. >>>More
