Repeat this procedure until the required size of test portion is obtained. BSI is incorporated by Royal Charter. NOTE 2 Steel slags might contain oxides of calcium and magnesium, which when in contact 133383-2 water these mineral phases will react to form hydroxides with a resultant increase in volume.

The water should be free from any impurity that would significantly affect its density. Method of sample reduction: The floor shall be sufficiently clean and close-textured to be able to distinguish and recover the material of the sample from the floor material. If a sampling increment of a light grading is too large for the preparation of the bulk sample, the procedure as specified in 4.

Take the smart route to manage medical device compliance. When discharging a sample 13383-2 a loader bucket, take all the material from a cross-sectional segment or from one side of an imaginary cross-sectional plane in the centre of the loader bucket, discharged between two parallel and vertically set plates or at one side of a vertically set plate. A reference method is specified. NOTE The testing of water 31383-2 is the first stage in the determination of the resistance to freezing and thawing of armourstone.

Determination of the water content by drying in a ventilated oven ISOTest sieves — Technical requirements and testing — Part 2: A comparison may be made between the test portion under test and the unboiled test portion. Enter the email address you signed up with and we’ll email you a reset link. Remove the warm test portion from the can and allow to surface dry.

The test method consists of soaking at atmospheric pressure and storage in water for thorough water absorption see 9. Usually hairline cracks are generated radiating out from the spots and interconnecting them. The sampling report shall refer to 1338-2 part of this European Standard and state: The test portion shall consist of one piece of armourstone or part thereof without open visible cracks.

If a sampling increment of a heavy grading is too large for the preparation of the bulk sample, the procedure as specified in 4. The sampling shall be carried out at intervals of 10 m along the length of the hold of the floating equipment. The distance between the cross-sections shall be determined by the required quantity of the sampling increment.

When one load contains insufficient material for one sample to be tested several loads shall be taken. 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.

Skip to main content. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Novemberand conflicting national standards shall be withdrawn at the latest by November Purpose for which armourstone is to be used: Execute the split by discharging the homogenised material over two adjoining receivers taking care to avoid any loss of material.

Where segregation is present in one direction of the deposited sample, place the wire in the same direction see Figure 2 and take the subsample by removing all armourstone located, or for the largest part located, at one side of the imagined vertical plane projected by the wire. The number of pieces of armourstone in a test portion shall be as specified in Table 2.

The sampling increments shall be spaced at approximately equal intervals, adjusted to take account of the required number of samples for the load to be sampled.

Estimate the 133383-2 of the heaviest piece of armourstone in the sample, mmax. We use cookies to make our website easier to use and to better understand your needs. If the test portion has fragmented during boiling, record the mass of the largest remaining fragment. Key 1 sample location 2 after partial unloading Figure H.

Worldwide Standards 133383-2 can source any standard from anywhere in the world. Second number of samples can directly be taken and sent to the laboratory together with the first number, or can be taken or sent to the laboratory if necessary depending on the test result of the first number.

The selection of the sampling scheme will depend on the relative size of the unloading equipment and the floating equipment. Wash the test portion, remove adherent particles by brushing, and dry to constant mass. When discharging a sample from a grab, take all the material from one symmetrical quarter or half of the grab content, discharged between two vertically set plates 31383-2 right angles to each other or at one side of 1338-32 vertically set plate.

During filling of a silo ne material segregates and as a result the finer material tends to be found in the centre of the silo with the coarser material along the wall sides. For other purposes, in particular factory production 31383-2, other methods may be used provided that an appropriate working relationship with the test method has been established.

NOTE The required number of sampling locations will depend on the length of the hold of the floating equipment. Where the test portion for water absorption is larger than the remaining part of the laboratory sample it shall be used as the freeze-thaw portion.

Those involved in the planning and execution of sampling should work closely with the operational management to ensure safe working practices. NOTE For guidance on numbers and sizes of samples and test portions for testing armourstone as specified in EN
