Name and address of party requesting the sample: The period during which the sampling is done shall be divided into a number 1333-2 equal intervals and a sampling increment shall be taken in the middle of each interval.
For further information on grading, see EN Calculate the water absorption Was as a percentage of the dry mass from the following formula: Determination of particle shape – Flakiness index EN NOTE The required number of sampling locations will depend on the length of the hold of the floating equipment. 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.
The crushing shall be carried out with a laboratory jaw crusher.
In the case of testing several test portions at the same time, these shall not be touching. 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.
When discharging a sample from a grab, catch all the material from one symmetrical quarter or half of the grab content in one or more buckets.
Sampling from static batches should be avoided wherever possible since it is difficult to satisfy the principle of taking sampling increments at random from all parts of the batch, and hence segregation is likely to cause the sampling to produce biased results.
This document supersedes EN This reduces the strength of the mineral fabric, and as a result the rock decays to small particles.
Reference to sampling plan used: Number of pieces of armourstone: NOTE It might be easier to allocate each piece of armourstone of the test sample to one of the 4 categories defined by successive reference stones and, then, count the number of pieces of armourstone in between successive reference stones. If water absorption is to be determined, the mass of the test piece shall not exceed g.
Worldwide Standards We can source any standard from anywhere in the world. When sampling 133383-2 unloading, sampling increments shall be taken with the aid of the unloading equipment.

Measure the thickness T at right angles to the laths using the carpenter’s rule or the tape measure. NOTE Copying of this form is permitted. Location of sampling point s: Users are responsible for its correct application. The distance between two parallel set plates shall be at least three times the sieve size of the nominal upper grading limit. For undated references, the latest edition of the referenced document including any amendments applies.
Mark the test portion for identification. For initial type testing and in cases of dispute the reference method should be used.
Estimate the mass of the heaviest piece of armourstone in the sample, mmax. Method of sample reduction: Every stone shall be fully visible and able to be compared with the reference pieces of armourstone.

Determination of the water content by drying in a ventilated oven ISOTest sieves — Technical requirements and testing — Part 2: Test laboratories can determine the time required to achieve constant mass for specific types and sizes 133383-2 sample dependent upon the drying capacity of the oven used.
When discharging a sample from a grab, take all the material from one symmetrical quarter or half of the grab content, discharged een two vertically set plates at right angles to each other or at one side of a vertically set plate. Chemical analysis  EN Calculate, to the nearest whole number, the cumulative percentage of pieces of 133383-2 Pn with a mass smaller than each specified mass in the mass distribution in accordance with the following formula: Take the smart route to manage medical device compliance.
Scheme 1 will 133833-2 more suitable when the unloading grab is small in comparison to the width of the barge, whereas Scheme 2 will be more suitable 13338-2 the unloading grab is larger.
A list of organizations represented on this committee can be obtained on request to its secretary. Remove the warm test portion from the can and allow to surface dry.
