TEST

CKS S.r.l. practices a series of durability tests on all the components typology and at last on the assembled structure of the chair, following the reference standards..
In particular, the tests differ in:

1. Durability test of the supporting structure of the chair (Ref.: UNI EN 1335-3:2000);
2. Durability test of the armrests (Ref.: UNI EN 1335-3:2000);
3. Durability test through rolling of carrying castors;
4. Durability test of supporting back mechanism and of the seat metal plate;
5. Durability test of the chair base ANSI-BIFMA X5.1-1993/8.
6. Colour average and deviation measurement CIE 1976 L*a*b*

All last generation machines are connected to our server to keep parameters under control, this allows us to have a complete overview over the test, with development of graphics and reports to verify the product quality.
At the client's request, CKS S.r.l. is abel to produce approval test.

 

1-Durability test of the supporting structure of the chair (Ref.: UNI EN 1335-3:2000)
This test is done by simulating 5 whole life cycle on the same structure (Ref.: UNI EN 1335-3:2000). Pressure is applied in different parts of the backrest and seat, in this way structure resistance is verified.

2-Durability test of the armrests (Ref.: UNI EN 1335-3:2000)
Pressure is applied on both armrests simultaneously. Grade simulates the process of sitting and raising.

3-Durability test through rolling of carrying castors
Test is done by sliding base and castors, on uneven surface, with a specific weight on seat. The number of cycle simulates castors sliding for 240 Km.

4-Durability test of supporting back mechanism and of the seat metal plateThe test simulate pressure on backrest support and mechanism.

5-Durability test of the chair base ANSI-BIFMA X5.1-1993/8Specific pressure is exerted for a minute and until bending is fixed, test can be done also with castors.

6- Colour average and deviation measurement CIE 1976 L*a*b*Colorimeter can be used on different material and surface. Absolute chromatic values (b.p.. to determinate chromatic position) or it can be used to determinate comparative measurements.
