proposals submitted by Working Group 1 ”Screed material and floor screeds - Definitions, properties and
requirements“.
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by endorsement, at the latest by May 2003, and conflicting national standards shall be withdrawn at the latest by
May 2003.

1 Scope
This European standard specifies a method for sampling of screed materials, making and curing of specimens for
subsequent testing.
This method applies to dry material (bagged or bulk) or to freshly mixed screed materials (ready mixed or site
mixed) or to products supplied in pre-packaged form or in packs ready for mixing.
samples of pre-packaged screed materials taken by the manufacturer during production and/or before dispatch, by
the contractor or client before or during the period of use and subsequently in cases of dispute by any interested
party and samples of the fully mixed product before laying.
This method applies to mortars of cementitious-, calcium sulphate-, magnesite- and synthetic resin screed material.
For mastic asphalt screed material see prEN 12697-20 and prEN 12697-21. Some methods according to
manufacturers instructions may be necessary for special synthetic resin screed material.

3 Sampling
3.1 Apparatus
A metal or rigid plastics receptacle or scoop of not less than 1 l capacity; Clean, dry, airtight containers which shall
be in that condition at the commencement of the sampling operation.
3.2 Procedure
The composition of samples shall always be representative of the average composition of the material. In the case
of pre-packaged products, the manufacturer’s recommendations for handling of the individual components should
be followed.
The test report shall state whether the samples taken are spot samples or composite samples (see 3.6 and 3.7 of
EN 196-7:1989)
The minimum amounts of sample material should be 5000 g. If a greater amount of screed material is required the
sample should contain a full package of the material (e.g. a 25 kg sack ).
Samples which are likely to change in air shall be placed in airtight containers, such as cans, immediately after they
have been taken.

The solid content of a prepared mixed screed material , or the volume of the fresh mixed screed material, shall be
within the range given in Table 1.
All the solid materials shall be put into the mixer and blended. The specified quantity of liquids shall be added over
a period of 15 seconds while the mixer is running at low speed. The mixing shall be continued at low speed for a
