23、15-2:1998 + A1:2006 (E) 4 3 Definitions For the purposes of this standard the following definitions apply. 3.1 lot quantity of mortar produced under conditions presumed uniform. After specified tests this quantity is regarded as a whole “complying” or “not complying” with the specifications 3.2 incr
24、ement quantity of mortar taken in a single operation of the sampling equipment used 3.3 bulk sample the aggregation of sample increments meant to represent the lot sampled 3.4 bulk test sample the reduced sample taken from the bulk sample which is used for the testing purposes of this standard 4 Min
25、imum bulk test sample size The minimum bulk test sample size shall be 10 kg. 5 Preparation of the bulk test sample and individual test samples 5.1 Apparatus 5.1.1 A metal or rigid plastics receptacle or scoop1)of not less than 1 l capacity. 5.1.2 Clean, dry containers with close-fitting lids. 5.1.3
26、A trowel or palette knife. 5.1.4 A flat shovel. 5.2 Procedure 5.2.1 General Obtain the bulk sample by taking uniformly distributed increments (preferably from material in motion, provided this can be carried out in safety), and mix thoroughly. Reduce the bulk sample in accordance with 5.3 to obtain
27、the bulk test sample. 5.2.2 Sampling from batch mixers Sample the mortar at the discharge point of a batch from the mixer. Take not less than three increments spaced evenly through the batch at the discharge point of the mixer. Take increments by passing the receptacle across the stream of mortar in
28、 such a manner as to collect a representative sample of mortar. 1) According to the method being used (see 5.2.3). EN 1015-2:1998 + A1:2006 (E) 5 5.2.3 Sampling from conveyors, pipelines etc. Sample the mortar at the discharge point of the conveyor or pipeline. Pass the receptacle across the stream
29、of mortar, if possible so as to cross the whole of the stream, until it is filled. If it is not possible to catch the whole stream at once, pass the receptacle through the stream at a uniform rate so that consecutive increments are taken from different parts of the stream. Where it is not possible t
30、o sample at the discharge point of conveyor, stop the conveyor and use the scoop (5.1.1) to take increments from the full width and thickness of the stream of mortar on the conveyor. Take not less than three increments at regularly spaced time intervals during the passage of the whole of the quantit
31、y of the mortar that is being sampled. 5.2.4 Sampling from large hoppers, bins, or heaps being moved Sample the mortar when hoppers etc. are being filled or emptied or when heaps are being moved, in accordance with 5.2.3. 5.2.5 Sampling from small hoppers, bins, static heaps, or bags Sample the mort
32、ar by means of the scoop. Take increments from material not less than 100 mm below the surface in at least three different places, distributed in a regular manner throughout the mass, so as to ensure, when mixed, a thoroughly representative combined sample. 5.2.6 Bulk transport vehicles Sample the c
33、ontents of bulk transport containers either during filling or emptying in accordance with 5.2.3 or, when this is not practical, by taking increments in accordance with 5.2.5. 5.3 Reduction of the bulk sample Immediately after collecting, using a flat shovel (5.1.4) combine and thoroughly mix the inc
34、rements, taken in accordance with any of the methods described, on a flat, impervious rigid surface. Care should be taken when lightweight or fibrous components are present in order to avoid segregation. Complete the mixing within 5 min of placing the increments upon the surface. Reduce the bulk sam
35、ple to produce a bulk test sample of not less than 10 kg by taking sufficient scoopfuls from random positions throughout the mixed material. Place the bulk test sample in one or more containers (5.1.2) with close-fitting lids. The sampling operation shall not take longer than 3 min. 5.4 Packing and
36、certificate of sampling Each bulk test sample to be despatched to a laboratory in the containers shall be suitably labelled so that its origin can be identified at the laboratory. The bulk test sample shall be accompanied by a certificate from the person responsible for taking the samples stating th
37、at sampling was carried out in accordance with the requirements of this European standard. This certificate shall include the following information: a) the name and address of the body responsible for sampling; b) the name and address of the customer; c) the place, date and time and method of produc
38、ing the bulk test sample; d) identification of the mortar sample, including type, origin and designation by reference to the relevant part of EN 998; e) he quantity of the lot, or the period of production represented by the bulk sample; EN 1015-2:1998 + A1:2006 (E) 6 f) the number of increments and
39、the mass of the original bulk sample; g) age of mortar when sampled; h) identification mark on sample container; i) remarks. In addition it is recommended that the following be added, if known: mixing procedure, i.e. mixer type and length of mixing period. 5.5 Laboratory examination of bulk test sam
40、ples Each bulk test sample received at the laboratory for test shall be examined visually to ascertain whether setting, leakage, or evaporation has occurred. If so, the bulk test sample shall be rejected for further tests, other than sieve analysis (assuming the sample has not hardened). If none of
41、the above factors is apparent, the whole of the sample, with any liquid that has separated, or has condensed on the inside of the container, shall be removed completely and mixed without loss of water to render it homogeneous. Where practicable, the temperature of the bulk test sample shall be adjus
42、ted to 20 C 5 C, without loss of water. In all cases the temperature of the sample at the time of test shall be recorded. 5.6 Time of testing Bulk test samples despatched to a laboratory for testing shall be tested immediately after arrival at the laboratory, and within the specified workable life o
43、f the mortar Test ready to use mortars (factory made wet mortars which are retarded), and pre-batched air-lime/sand wet mortars when not gauged with hydraulic binders, within their specified workable life. 6 Preparation of test mortars from dry constituents and water or prebatched mixes and binders
44、6.1 Amount of mortar for test samples The solid content of a prepared mortar mix, or the volume of the fresh mortar mix, shall be within the range given in Table 1. Table 1 Solid content and volume of the mortar mix Fresh mortar mix Mixer according to EN 196-1 Pan mixer Solid content (kg) 1,83,0 305
45、0 Volume (dm3) 0,52,5 2575 6.2 Mixing the mortar 6.2.1 General Fresh mortar used for the purpose of testing and preparing specimens for tests shall, as far as possible, have the consistence appropriate for its use. Unless otherwise specified, bring the fresh mortar sample to a defined EN 1015-2:1998
46、 + A1:2006 (E) 7 flow value as specified in Table 2, and determined in accordance with EN 1015-3. The water content needed to achieve this consistence is determined by the use of trial mixes.

If such instructions are not available, follow the mixing procedure described in 6.2.2 or 6.2.3. Mix with the amount of water
48、 expected to give a mortar with the intended consistence. Measure the length of the mixing period from the moment all constituents are introduced into the mixer. Record any deviation from the mixing procedure prescribed. 6.2.2 Mixer according to EN 196-1 After the predetermined amount of water has b
49、een introduced into the mixer, add the solid content of the dry mortar mix, as given in Table 1, over a period of 30 s with the mixer running at low speed. For lightweight mortars correspondingly reduce the amount and take from a vessel as an average sample. Then complete mixing at the same speed for a further 60 s unless otherwise specified by the manufacturer2). Follow the same procedure also for factory made mortars to which only water is to be added. For pre-batched mortars to which binders also are to be added,
