DIN EN ISO 9117-1:2009-10 “” he secretariat of1 Scope This part of ISO 9117 specifies a test method for determining under standard conditions whether a single coat or a multi-coat system of paint,

23、 varnish or related material has reached the through-dry state after a specified drying period. NOTE The test procedure may also be used to determine the time taken to achieve that state. 2 Normative references The following referenced documents are indispensable for the application of this document

26、s document, the following terms, definitions and abbreviated terms apply. 3.1 IRHD scale international rubber hardness degree scale 3.2 through-dry state condition of a film in which it is dry throughout its thickness NOTE 1 The through-dry state should not be confused with the condition in which th

27、e surface of the film is dry but the bulk of the coating is still mobile. DIN EN ISO 9117-1:2009-10 EN ISO 9117-1:2009 (E) 4NOTE 2 For the purposes of this part of ISO 9117, a single coating or a multi-coat system of paint or varnish or related material is considered to be through-dry when a specifi

28、ed gauze under specified pressure, torsion and time does not damage the film. 3.3 through-dry time period of time between the application of a coat to a prepared test panel and the achievement of the through-dry state, as determined by the specified test procedure 4 Principle A coat of paint or varn

29、ish of agreed thickness is applied to a substrate and is allowed to dry under specified conditions. The completeness of drying throughout the coat is determined by examination of the surface of the coat after the application of a load, applied over a given area of the surface, and subsequent rotatio

30、n of the load-applying face through 90. 5 Apparatus and materials Ordinary laboratory apparatus and glassware together with the following: 5.1 Baseplate and plunger assembly (see Figure 1 and Figure 2), consisting essentially of a baseplate and a free-sliding plunger. The plunger head shall have a d

31、iameter of at least 25 mm. It shall be designed in such a way that the underside of the head can align itself with the upper surface of the test panel. NOTE 1 If the mass of the plunger is not greater than 250 g, the apparatus described in ISO 46221is suitable for the test. DIN EN ISO 9117-1:2009-10

32、 EN ISO 9117-1:2009 (E) 5 Key 1 weights 2 plunger 3 ball joint 4 plunger head 5 baseplate Figure 1 Baseplate and plunger assembly A rubber disc (5.2) shall be attached to the centre of the underside of the plunger head using tape coated on both sides with adhesive. There shall be a device to firmly

33、clamp a gauze (5.3) to the test face, and the plunger head shall be able to be rotated through 90. NOTE 2 It is recommended that a ball-joint connection be present between the plunger and its head and that, for reasons of economy, the plunger specified in ISO 4622 be used. 5.2 Flat rubber disc, of d

34、iameter (22 1) mm, thickness (5 0,5) mm and hardness (50 5) IRHD (see ISO 48). NOTE For reasons of economy, it is recommended that the rubber disc specified in ISO 36782be used. 5.3 Gauze, of woven monofilament polyamide, minimum size 100 mm 100 mm. The gauze thread diameter shall be 0,120 mm and th

35、e gauze aperture approximately 0,2 mm. 5.4 Weights, giving a total mass of (1 500 10) g. 5.5 Stopwatch, accurate to 0,1 s.

36、g assembled plunger head 6 Sampling Take a representative sample of the product to be tested (or of each product in the case of a multi-coat system), as described in ISO 15528. Examine and prepare each sample for testing, as described in ISO 1513. 7 Test panels 7.1 Substrate Select as the substrate

37、three test panels (or six if both the through-dry state and the through-dry time are to be determined) of a type described in ISO 1514, where possible ensuring that the substrate is equivalent to the intended application. 7.2 Preparation and coating Prepare the test panels (see 7.1) in accordance wi

38、th ISO 1514 and then coat them with the product or system under test by the specified method to the thickness specified for the dry film. The coating method and dry film thickness shall be as specified by the manufacturer, or agreed between interested parties, and included in the test report see Cla

39、use 10, items c) 2) and c) 3). DIN EN ISO 9117-1:2009-10 EN ISO 9117-1:2009 (E) 78 Procedure 8.1 Preparation of apparatus Clamp the gauze (5.3) over the rubber disc (5.2) under the plunger head (see Figure 2), taking care to ensure that the exposed surface of the gauze is free from creases. Take a f

40、resh piece of gauze for each test. 8.2 Drying the test panel Dry (or stove) and age, if applicable, each coated test panel in a horizontal position with free circulation of air, but shielded from draughts and direct sunlight, for the specified time under the specified conditions. The drying (or stov

41、ing) and aging time and conditions shall be as specified by the manufacturer, or agreed between the interested parties, and included in the test report see Clause 10, items c) 4) and c) 5). 8.3 Determination of through-dry state 8.3.1 On completion of the specified drying time (see 8.2), place a tes

42、t panel on the baseplate. 8.3.2 Place the weights (5.4) on the top of the plunger. Gently lower the plunger so that the gauze is in contact with the test panel. Start the stopwatch (5.5) and allow the plunger to remain in this position for (10 1) s. 8.3.3 At the end of this period, turn the plunger

43、head through an angle of 90 over a period of about 2 s. Immediately raise the plunger, remove the test panel and examine the coat in the test area using the naked eye. 8.3.4 Repeat the procedure in 8.3.1 to 8.3.3 on two additional coated panels. 8.3.5 If no damage is observed on any of the three tes

44、t surfaces, report the result as “through-dry state achieved”. If damage is observed on one or more of the three test surfaces, report the result as “through-dry state not achieved”. Some coatings do not reach a point where they are totally unaffected by the test (i.e. a point where no mark, for ins

45、tance, is left on the surface by the gauze), even when they have reached a functionally acceptable state of drying or cure. In such cases, the time when the coating reaches the stage at which the action carried out in the test does not cause deterioration of the coating to an extent where it could n

46、ot perform its ultimate function shall be quoted. For some coatings, e.g. those which are applied to protect the substrate rather than for cosmetic reasons, marking of the surface would not constitute an inability of the coating to perform its function. For highly pigmented coatings, the action of t

47、he gauze can cause polishing of the surface, leaving marks which might not be detrimental to the coatings ultimate function. In such cases, all observations shall be recorded in the test report. Take care to avoid confusion between cohesive failure within the coat (a failure under this test) and fai

48、lure of the coat to adhere to the substrate (not a failure under this test). 8.4 Determination of through-dry time 8.4.1 On completion of the specified drying time (see 8.2), place a test panel on the baseplate. 8.4.2 At appropriate intervals, carry out the test described in 8.3.2 and 8.3.3. Examine

49、 the coating in the test area for damage. Stop the test when no damage occurs to the coat (see 8.3.5). 8.4.3 Repeat the procedure in 8.4.1 and 8.4.2 on two additional coated panels. 8.4.4 Report the longest time taken in the three tests for the coat to reach the through-dry state.
