Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern=
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 8130-9 was prepared by Technical Committee
ISOITC 35, Paints and varnishes, Sub-Committee SC 9, General test
methods for paints and varnishes.
IS0 8130 consists of the following parts, under the general title Coating
powders:
- Part I: Determination of particle size distribution by sieving
- Part 2: Determination of density by gas comparison pyknometer
(referee method)
- Part 3: Determination of density by liquid displacement
pyknometer
- Part 4: Calculation of lower explosion limit
- Part 5: Determination of flow properties of a powder-lair mixture
- Part 6: Determination of gel time of thermosetting coating powders
at a given temperature
- Part 7: Determination of loss of mass on stoving
- Part 8: Assessment of the storage stability of thermosetting pow-

Coating powders -
Part 9:
Sampling
1 Scope
This part of IS0 8130 describes methods for the
sampling of coating powders from consignments
and for the subdivision of the sample into quantities
suitable for undertaking appropriate test methods
specified in the other parts of IS0 8130.
It is assumed that this part of IS0 8130 will be used
and applied by those who are appropriately qualified
and experienced. The procedures are intended to
be carried out by suitably trained and/or supervised
personnel.
2 Definitions
For the purposes of this part of IS0 8130, the follow-
ing definitions apply.
2.1 lot (batch): A definite quantity of coating pow-
der manufactured or produced under conditions
presumed to be uniform.
2.2 consignment: A definite quantity of coating
powder issued and received as one delivery and
covered by one set of documents. The consignment
may consist of one or more lots or parts of lots.
3 Apparatus
3.1 Sampling scoop, of non-sparking metal and of
semicircular or C-shaped cross-section (see
figure I), capable of boring out a core of material
from the full depth of the container. Figure 1 - Typical sampling scoops
