Fixture to test compression properties of conduit systems for cable management according to DIN EN61386-1. 

Sample length is 200mm.  

Compression platen size diameter 240mm.  top compression head is 50mm*50mm*50mm 

10.2.1 Samples of conduit, each 200 mm long, shall be subjected to a compression testat(23+2)°C,using the apparatus shown in Fiqure 1.

10.2.2 Before the test, the outside diameters of the samples shall be measured.

10.2.3 The samples shall be positioned on a flat steel support, and a steel intermediatepiece, as shown in Figure 1, shall be placed in the middle of the sample.

10.2.4 A uniformly increasing compression force, reaching the values shown in Table 4within (30 ±3)s, shall be applied to the intermediate piece.

10.2.5 After the force given in Table 4 has been applied for (60 + 2) s, the outside diameteiof the sample shall be measured where flattening has taken place, without removing the force

10.2.6 The diference between the initial outside diameter and the diameter of the flattenedsample shall not exceed 25 % of the initial outside diameter measured before the test.

10.2.7 The force and the intermediate piece are then removed and, (60 + 2) s after removal.

the outside diameter of the samples, where they have flattened, shall be measured again.

The difference between the initial diameter and the diameter of the flattened samples shall notexceed 10 % of the outside diameter, measured before the test.

10.2.8 After the test, the samples shall show no cracks visible to normal or corrected visionwithout additional magnification.
