When one load contains insufficient material for one sample to be tested several loads shall be taken. We use cookies to make our website easier to use and to better understand your needs.

The sampling shall be carried out at intervals of 10 m along the length of the hold of the 133383-2 equipment.

The selection of the sampling scheme will depend on the relative size of the unloading equipment and eb floating equipment. At the beginning and the ending of the sampling the edge of the bucket shall pass the cross-section of the stream as fast as possible.

If these details are to be used 1333-2 any other purpose than implementation then the prior written permission of BSI must be obtained. For heavy gradings, the sampling increment may ej be a single piece of armourstone and in this case considerably more than 6 sampling increments will be needed to meet the requirements of Table 1 below. Please download Chrome or Firefox or view our browser tips. Ensure that all pieces of armourstone which may pass the sieve in any orientation have so passed before the retained material is placed on the subsequent sieve.

This reduces the strength of the mineral fabric, and as a 1383-2 the rock decays to small particles. The sampling increments shall be taken at random or at equal distances around the stockpile or part thereof to be sampled.

This publication does not purport to include all the 133883-2 provisions of a contract. When this gives too large a sampling increment, it should be reduced by one of the methods described in 4. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.


When reducing a sample already discharged onto a floor area 4.

A sample increment shall be taken by catching the discharge stream in a loader e, making sure that the complete cross-section of the stream of material is intercepted. Common equipment and calibration ENTests for geometrical properties of aggregates — Part 1: Take the smart route to manage medical device compliance.

Record the percentage to the nearest whole number.

Estimate the mass of the heaviest piece of armourstone in the sample, mmax. NOTE For guidance on numbers and sizes of samples and test portions for testing armourstone as specified in EN Key 1 sample location 2 after partial unloading Figure H.

Execute the split by discharging the homogenised material over two adjoining receivers taking care to avoid any loss of material.

The sampler shall be informed of the aim of the sampling. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Calculate the average mass of the pieces of armourstone heavier than a fragment Mem in kilograms to the nearest 1 kg in accordance with the following formula: Armourstone from which no sampling increment can be taken because it is not accessible, or for some other practical reason shall not be considered to be part of the batch that is represented by the samples.

Location of sampling point s: The use of other methods not described in this standard for determining mass distribution are permitted, in particular for factory production control, provided that an appropriate working relationship with the reference method has been established.

The capacity of the balance shall be suitable to allow the fn basket containing the sample to be suspended and weighed in water. Specifies sampling and test methods for natural, artificial and recycled aggregates for use as armourstone.

Sampling increments are selected at random from all parts of the batch that the samples are to represent. Every stone shall be fully visible and able to be compared 133832- the reference pieces of armourstone. Each piece of armourstone shall be marked clearly and durably with the allocated number.


When using this table, the following possibilities for using samples for testing several properties can be taken into account: Based on a visual assessment of the mass of each individual piece of armourstone of the sample, count and record the number of pieces of armourstone with mass between that of successive reference stones. With a continuous process the quantity produced during an agreed period is treated as a batch.

Determination of the water content by drying in a ventilated oven ISOTest sieves — Technical requirements and testing — Part 2: The test portion shall consist of a single piece of armourstone or part thereof with a mass of at least g.

EVS-EN 13383-2:2002

The version has been reinstated. Where segregation is present in one direction of the deposited sample, place the wires in the same direction see Figure 3 and take the subsample by removing all stones located, or for the largest part located, between the imaginary vertical planes projected by the wires. The crushing shall be carried out with a laboratory jaw 1333-2.

However, several such test portions can be tested at the same time and share both an oven and low temperature cabinet. Examine sn record crack formation. The number of pieces of armourstone heavier than fragments in the test portion of heavy and light gradings shall be as specified in Table 1. Otherwise the majority of the changes from the previous version are editorial. This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations.

Example of a mass distribution determined by bulk weighing method Laboratory: The procedure is based on the testing of a test portion consisting of one piece of armourstone or part thereof, but it is permitted that several such test portions may be tested at the same time and share the boiling.
