EN 14713:2016 (E) DIN EN 14713:2016-10 4 Introduction The friction behaviour is described by a characteristic coefficient of friction, independent of the test apparatus and test conditions. As the coefficient of friction of potentially adhes

21、ive films or layers may be a function of the normal force, FN, and the contact surface and, in the case of dynamic friction, also of the relative speed and other dynamic parameters, these parameters have also been specified in this European Standard. The tests can be carried out with the potentially

22、 adhesive layers sliding over themselves or coated side over the reverse side of a substrate or other surfaces of metals or plastics. The coefficient of friction does not allow a comprehensive assessment to be made of the machinability on packaging or processing machines as under the conditions enco

23、untered in practice, the friction phenomena are generally accompanied by other effects, e.g. electrostatic charges, air cushion, local rise of temperature, abrasion, etc. SAFETY STATEMENT Persons using this document should be familiar with the normal laboratory practice, if applicable. This document

24、 does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory conditions. ENVIRONMENTAL STATEMENT It is understood that some of the mater

25、ial permitted in this standard may have negative environmental impact. As technological advantages lead to acceptable alternatives for these materials, they will be eliminated from this standard to the extent possible. At the end of the test, the user of the standard should take care to carry out an

26、 appropriate disposal of the wastes, according to local regulation. EN 14713:2016 (E) DIN EN 14713:2016-10 5 1 Scope This European Standard specifies test methods to assess the coefficients of friction of potentially adhesive films or layers, such as coatings with reactivable adhesives, hot melts or

27、 waxes, for use with paper and board, packaging and disposable sanitary products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

29、 and definitions apply. 3.1 friction resistance against sliding of two surfaces in contact with each other Note 1 to entry: A distinction is made between static friction and dynamic friction. 3.2 static friction threshold value of the friction between two relatively static bodies, where the force ap

30、plied is insufficient to cause relative motion which has to be overcome at the onset of sliding motion 3.3 dynamic friction friction between two bodies in relative motion to each other which remains after the static friction has been overcome at the given sliding speed 3.4 static frictional force FS

31、force necessary to overcome the static friction 3.5 dynamic frictional force FDforce necessary to overcome the dynamic friction 3.6 normal force FNforce acting perpendicularly to the two surfaces in contact 3.7 coefficient of friction ratio of the frictional force to the normal force EN 14713:2016 (

The te

33、st apparatus consists generally of a driving mechanism to produce a uniform relative motion between two sliding surfaces and a load cell to record the frictional force. The relative motion between the two surfaces may be produced in any suitable way, e.g. by means of a moving table (see Figure 1a) o

34、r by moving the measuring device in the opposite direction. Even the vertical motion of a tensile testing machine may be utilized if the frictional force or the motion that induces the friction is deflected in the vertical direction by a pulley (see Figure 1b). The force is recorded continuously by

35、means of a suitable recording device.

36、s for the determination of friction properties EN 14713:2016 (E) DIN EN 14713:2016-10 8 The test apparatus shall meet the following requirements: 1) supporting surface of the testing table (see 3 in Figure 1) shall be flat and smooth; 2) normal force shall be generated by a sledge (see 1 in Figure 1

37、) with a square-shaped contact surface of approximately 4 000 mm2and an edge length of 63 mm. For the purpose of uniform distribution of pressure, the base of the sledge shall be covered with an elastic material 2 mm to 3 mm thick, e.g. rubber. Care shall be taken to ensure that the structure of thi

38、s material is smooth enough to avoid embossing thin layers. The total mass of the sledge shall be (200 2) g; 3) motion that induces the friction process shall be free of vibration and shall have a speed of (100 10) mm/min; 4) deviation of the force measuring system, including the recording instrumen

39、t, shall not exceed 2,5 %. The direction in which the frictional force is applied shall be in line with the frictional plane; 5) for the measurement of static friction, the coefficient of elasticity of the force measuring system shall be adjusted to (2 0,2) N/cm by means of an interconnected spring.

40、 For the measurement of the dynamic friction, the spring shall be replaced by a rigid connection if the vibromotive force effect occurs. The inertia of the mass of the sledge induces an additional force at the beginning of the sledge movement. Thus, the coefficient of friction is increased by a slig

41、ht amount : =/Dmvg(1) where v is the speed of the sledge relative to the testing table; m is the mass of the sledge; g is the acceleration of gravity (= 9 810 mm/s2); D is the coefficient of elasticity. 5 Test specimens 5.1 Sampling Take a sample of the adhesive to be tested in accordance with EN IS

42、O 15605. Examine and prepare it for testing in accordance with EN 1067. 5.2 Preparation of test specimens For each measurement two test specimens, each measuring approximately 80 mm 200 mm, are required. At least three such pairs, uniformly distributed over the width of the sheeting, or in the case

43、of tubular film, over the circumference, shall be tested. Unless otherwise specified, the longitudinal axis and thus the testing direction shall be parallel to the direction of the film or of the wax or adhesive coating. Extreme care shall be taken when handling the test specimens. Fingerprints, dus

44、t and any other foreign matter shall be avoided. EN 14713:2016 (E) DIN EN 14713:2016-10 9 Testing of three pairs of test specimens represents a minimum for estimating the scatter. Depending on the intended precision and the homogeneity of the material under test, the number of tested specimens may h

45、ave to be increased. Many films contain additives, which may migrate to the surface during the conditioning period and alter the frictional properties. As these effects are time-dependent, results of measurements made on these films shall be related to the date of manufacture of the film. 6 Procedur

46、e 6.1 General For the tests described in 6.2 and 6.3, apparatus as shown in Figure 1 shall be used. If a different, but equivalent arrangement is used, the procedure shall still be the same. Any deviations from the parameters specified, in response to special conditions encountered in practice, shal

47、l be stated in the test report see 8 h). 6.2 Friction measurement A: Coating against coating Fix the first specimen (see Figure 1) to the testing table with double-faced adhesive tape, the longitudinal axis of the specimen coinciding with that of the testing table. Lay the second specimen on top of

48、the first one and place the sledge on top gently without shock or additional pressure, connect to the load cell via the spring, the connection to the load cell shall not yet be tensioned. The clearance shall not exceed 2 mm. After 15 s, start the motion of the testing table and the recording of the

49、frictional force. After approximately 60 mm travel, the test may be ended. If, after the static friction has been overcome, the vibromotive force effect occurs, the oscillations of the force on the graph mean that the dynamic frictional force cannot be determined. In this case, the dynamic coefficient of friction shall be determined by a separate measurement (on new specimens), the spring being replaced by a rigid connection. 6.3 Friction measurement B: Co
