CAS number: 67953-76-8
The test item was formed into a powder train. In the preliminary
screening the test substance doesn`t ignite by a hot flame from a gas
The pile failed to ignite during the
two minutes that the Bunsen burner flame was applied.
The result of the preliminary
screening test obviated the need to perform the main test.

Moisture content (% w/w)
Mean moisture content (% w/w)
General physico-chemical properties of
the test item have been determined.
Methods employed are designed to be
compatible with those specified in Commission Regulation (EC) No
440/2008 of 30 May 2008, Part A: Methods for the determination of
The flammability (solids) was
determined by measuring the burning rate of test item prepared as a pile
of set dimensions. Testing was conducted using a method designed to be
compatible with Method A10 Flammability (Solids) of Commission
Regulation (EC) No 440/2008 of 30 May 2008.
The test item has been determined to
be not highly flammable as it failed to ignite in the preliminary
Potassium salts of HEDP are
involatile and are demonstrated to have high melting temperature of
>450°C. The requirement to test the substance for pyrophoricity and
flammability in contact with water was waived in accordance with Section
1 of REACH Annex IX, because there is no indication on the basis of
structure and experience in use and handling that the substance is
pyrophoric (flammable in contact with air) or flammable in contact with
screening studies were performed with HEDP acid and HEDP-4Na according
to test method A.10 flammability of solids. In both cases the test
material failed to ignite and no further testing was performed. These
results are read-across to potassium salts of HEDP as
the salts are not expected to exhibit higher flammable properties than
their corresponding acids.
salts of HEDP are not classified for flammability based on read-across
from HEDP-acid and HEDP-4Na. Both substances failed to ignite in
preliminary screening studies performed in accordance with EU test
