Table 1 and the description of 6.4 have been clarified and improved. Apart from this various smaller adjustments have been made. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1426:2015
The use of the needle-holder of (97,50 ± 0,05) g without additional weight is also possible. Equipment that controls the penetration time automatically may also be used. Such equipment shall be checked regularly for correct penetration time (see 5.6). 5.2 Penetration needle, (see Figure 2) 5.2.1 Penetration needle specifications made from fully hardened, tempered and polished stainless steel of type X105CrMo17 (1.4125), conforming to EN 10088-3, taking into account that it is not necessary to comply with the minimum content of molybdenum specified in that standard, and of Rockwell hardness C54 to C60 determined in accordance with EN ISO 6508-1. The cylindrical body of the needle shall have a diameter of 1,00 mm to 1,02 mm and one end shall be symmetrically tapered by grinding to a cone with an angle between 8°40’ and 9°40’ over the entire cone length. The cone shall be co-axial with the cylindrical body of the needle; the total axial variation of the intersection between the conical and cylindrical surfaces shall not exceed 0,2 mm. Further dimensional details of the penetration needle see Figure 2. The conical tip of the needle shall be ground square to the axis of the needle within 2 ° until the diameter at the tip is between 0,14 mm and 0,16 mm. For penetrations up to (330 × 0,1) mm the length of the needle shall be approximately 50 mm. For penetrations between (330 × 0,1) mm and (500 × 0,1) mm, use needles that shall conform to the requirements given for mass and dimensions, but which are longer in length so that the ferrule into which the needle is fixed does not penetrate the material undergoing testing. The needle shall be rigidly mounted in a brass or stainless steel ferrule with 5 mm to 10 mm of the needle inside the ferrule. The run-out of the needle tip or any part of the needle relative to the ferrule axis shall not exceed 1,0 mm. The ferrule shall be (3,10 ± 0,15) mm in diameter and (38 ± 1) mm in length. The ferrule of the penetration needle shall fit firmly into the needle holder. The mass of the ferrule and needle assembly shall be (2,50 ± 0,05) g. NOTE 1 A drill hole at the end of the ferrule or a flat on the side is possible to control the mass. Individual identification marking shall be engraved or stamped on the ferrule of each needle; the same marking shall not be repeated by the manufacturer within a 3 year period. NOTE 2 For information concerning tolerances of the needle (Figure 2), see ISO 286-1, EN 1829, EN ISO 1101 and EN ISO 1302. 5.2.2 Continuous check of penetration needle by lab
It is important that initial and continued compliance with the stringent requirements for the needle is maintained. Certification of compliance shall be obtained through the needle supplier or a qualified agency. SIST EN 1426:2015
The verification of the conical tip of the needle can be performed with binocular magnifying glasses or a microscope. A visual control of the run-out of the needle shall be performed by rolling the needle on a table. The mass of the needle plus needle holder together with the additional mass of the weight provides a moving load of (100,00 ±0,10) g. 5.3 Test sample container, metal or glass, cylindrical, flat-bottomed. The internal depth of the container shall be appropriate in order to contain a bituminous sample of which the depth shall be at least 10 mm greater than the expected penetration, and not less than 35 mm and shall not exceed 60 mm. The internal diameter of the container shall be at least 55 mm and shall not exceed 70 mm. NOTE 1 Recommended dimensions of the test sample container are given in Table 1. Table 1 — Informative - Recommended dimensions of the test sample container (see normative details in 6.4) Penetration (0,1 mm) Internal depth (mm) Internal diameter (mm) Approx. volume of sample (mL) Approx. cooling time in air or conditioning time in water (min) penetration < 160 35 55 80 60 160 ≤ penetration < 330 45 70 170 75 330 ≤ penetration ≤ 500 60 70 230 90 If insufficient binder is available (e.g. if it was obtained by extraction of a bituminous mix core or while monitoring short- or long-term ageing development) use a small stainless steel container. In order to fulfil the requirements of 7.4.2, the container shall have an inner diameter of at least 35 mm and a wall thickness between 1,5 mm and 2,0 mm. For penetrations lower than (100 x 0,1) mm, the inner height of the container shall be at least 20 mm. For penetrations from (100 x 0,1) mm up to (200 x 0,1) mm, the inner height of the container shall be at least 30 mm. To ensure a good stable temperature during testing, the container shall be placed in a brass ring with an inner diameter within 0,5 mm of the outer diameter of the sample container and a height of (21 ± 1) mm or (31 ± 1) mm. Report deviation from standard test conditions under Test report e). NOTE 2 The precision of the penetration values determined using the metal ring can be different from those given in Clause 9. 5.4 Water bath (constant temperature bath), w
