approved by CEN as a European Standard without any modification © BSI 12-1999 EN 29048:1990 Scope and field of application Procedure This International Standard specifies a method for the determination of extrudability of one-component or multi-component sealants regardless of the kind of packages in which they are supplied or from which they are applied to the joint in buildings 7.1 General NOTE A method for the determination of the extrudability of one-component sealants from the packages in which they are supplied is given in ISO 8394 References ISO 228-1, Pipe threads where pressure-tight joints are not made on the threads — Part 1: Designation, dimensions and tolerances ISO 2009, Slotted countersunk head screws (common head style) — Product grade A ISO 2338, Parallel pins, unhardened ISO 6927, Building construction — Jointing products — Sealants — Vocabulary Definitions For the purposes of this International Standard, the definitions given in ISO 6927 apply Principle Extrusion of a defined volume of sealant from a standardized device under defined conditions by means of compressed air Reporting of the extrudability as extruded volume per time unit, in the case of multi-component sealants by plotting a diagram Apparatus 5.1 Extrusion device, for pneumatic operation according to Figure and Figure for a test volume of approximately 250 or 400 ml and with an orifice diameter of 2, 4, or 10 mm as stipulated in relevant requirement standards or as agreed 5.2 Air compressor, with valve and pressure gauge to maintain the supply of compressed air at 200 ± 2,5 kPa and with an appropriate connection to the extrusion device 5.3 Graduated glass cylinder, of 000 ml capacity 5.4 Stop watch, calibrated in seconds Conditioning The sealant to be tested and the apparatus shall be conditioned at ± °C and/or 23 ± °C and at (50 ± 5) % relative humidity for at least h © BSI 12-1999 The test procedure shall be carried out at 23 ± °C and at (50 ± 5) % relative humidity Fit the piston and ring of the extrusion device (5.1) together and insert in the cylinder with the ring towards the orifice Fill the cylinder with the sealant without producing any bubbles In the case of multi-component sealant the filling shall be done immediately after the components have been mixed according to the requirements of the manufacturer Flush the surface of the sealant before the orifice cap, slide bar and orifice plate are put on the cylinder Choose the cylinder volume and orifice diameter according to the stipulations of the relevant requirement standards or as agreed upon between the parties involved Where a sealant which has been conditioned at more than one of the temperatures stated in clause is tested, the same cylinder volume and orifice diameter shall be used Set the filled extrusion device (5.1) under an air pressure of 200 ± 2,5 kPa (5.2) with the slide bar closed and keep it constantly under this pressure during the whole test Before starting measurement extrusion, extrude or cm of sealant to fill the orifice of the extrusion device 7.2 Testing of one-component sealants Extrude all of the sealant in the extrusion device (5.1) in one movement and measure the time required Calculate the extrusion rate from the chosen test volume and the extrusion time in millilitres per minute 7.3 Testing of multi-component sealants Place 500 ml of deionized or distilled water in the graduated glass cylinder (5.3) and read the level of water Then extrude approximately 50 ml of the sealant from the extrusion device (5.1) into the water and record the time required Read and record the level of water for its exact volume The first extrusion shall be performed 15 after beginning of the mixing of the components Repeat the procedure at least three times, that is, extruding approximately 50 ml each time and recording the time required and the exact volume Using the time required for each volume of sealant at suitable intervals of time, develop a volume/time graph so that a curve can be plotted which shows the extruded volume per minute at any time within the application life of the sealant as specified by the manufacturer EN 29048:1990 Test report The test report shall include the following information: a) reference to this International Standard; b) name and type of sealant; c) batch of sealant and age, if possible; d) conditions of mixing and mixing device in the case of multi-component sealants; e) volume of sealant tested (cylinder volume) and orifice diameter used; Reference No Quantity 10 11 12 13 1 1 1 1 1 14 a f) extrusion rate in millilitres per minute, in the case of one-component sealants for each conditioning temperature applied; g) diagram of volume/time curve and average extrusion rate in
