33、ter below 25 mm while for briquettes the diameter is higher (see ISO 17225-1). To account for the different particle dimensions, it was necessary to define different test apparatuses for determination of durability for pellets and briquettes.DIN EN ISO 17831-1:2016-05 EN ISO 17831-1:2015 (E)5 1 Scop
34、eThis part of ISO 17831 defines a determination method for testing the mechanical durability of pellets. The mechanical durability is a measure of the resistance of compressed fuels towards shocks and/or abrasion as a consequence of handling and transportation.2 Normative referencesThe following doc

38、ecified rotating test chamber. The durability is calculated from the mass of test portion, after separation by sieving of particles less than 3,15 mm, and the mass of the test portion after tumbling.5 Apparatus5.1 Pellets testerThe structure and dimensions of the pellet tester are shown in Figure 1

40、the pellets and a driving mechanism.The box shall have an internal smooth surface and projections such as rivets and screws shall be kept to a minimum and well rounded (alternatively flathead screws can be used). A door can be placed at any side.Specification of box and inner dimensions:Material: st

The baffle ex
42、tends (50 1,0) mm into the box (see Figure 1) and is securely fastened to the back of the box. The edges of the baffle shall not be sharp but rounded to avoid any cutting effect.DIN EN ISO 17831-1:2016-05 EN ISO 17831-1:2015 (E)7 The box shall be capable of rotating at a constant speed of (50 2) r/m
43、in by means of an electric motor with suitable pulleys or gear in order to avoid vibrations. A rotation counter shall be connected to the drum.The rotation counter can also be connected to the motor for automatic shut-off after a defined number of rotations.5.2 SieveThe sieve shall have a screen wit
44、h 3,15 mm diameter round holes and suitable for manual screening (see ISO 3310-2). The recommended diameter of sieve is 400 mm or above.5.3 BalanceThe balance shall be capable of reading to the nearest 0,1 g and a weighing capacity of 2 kg.6 Sample preparationA laboratory sample of minimum 2 kg mate
45、rial for the determination of mechanical durability shall be obtained in accordance with ISO 18135 and prepared in accordance with ISO 14780. The test sample shall be divided into four equal test samples.One test sample shall be used for determination of the total moisture content in accordance with
46、 ISO 18134-1 or ISO 18134-2.Simultaneously for the determination of the durability each of the remaining three test samples shall be sieved separately in order to remove the fines (particles less than 3,15 mm) using a sieve as described in 5.2.The sieving shall be performed by manually shaking each
47、of the test portions in about 5-10 circular movements. The recommended amount of material in the sieve shall be less than 0,8 g/cm2of sieve area. This requirement will be achieved for example by using a sample of 1,0 kg on a sieve 400 mm diameter. If a sieve with a different diameter is used, the am
48、ount of the material shall be adjusted to achieve the same degree of filling.The three test samples may be unified and divided into two portions in preparation for the tumbling (7.1).7 Procedure7.1 Tumbling procedureSelect one of the test portion of (500 10) g from the unified sample (see Clause 6).
