based on experience on site
NOTE The use of the recommended dosage does not imply that compliance with this standard will be achieved over the
whole range. Trial tests should be carried out with the materials to be used on site, to find the dosage necessary to achieve the
required result.
3.6
maximum recommended dosage
upper limit of the recommended range of dosage
4 Requirements
Masonry mortar admixtures, when sampled in accordance with EN 934-6:2001 and EN 934-6/A1, shall comply with
the requirements in EN 934-1:2008, Table 1 using the test methods listed therein and the additional requirements
specific to different types of admixture listed in Table 1.
NOTE 1 Tests should be carried out with the admixtures and other materials intended to be used in the mortar to check
whether the desired effect can be obtained.
For content of substances and release of substances from the hardened mortar which are dangerous to health,
hygiene and the environment see Annex A (informative).
NOTE 2 For requirements necessary for CE-marking see Annex ZA.
