Coating powders - Part 4: Calculation of lower explosion limit (ISO 8130-4:1992, including Cor 1:1993)

In clause 6, replaces in the definition of the symbol B "1,24 × 10^4 J/m^3" by "1,24 × 10^6 J/m^3".

Pulverlacke - Teil 4: Berechnung der unteren Zündgrenze (ISO 8130-4:1992, einschließlich Cor. 1:1993)

Dieser Teil von ISO 8130 legt ein Verfahren zum Berechnen der unteren Zündgrenze eines Pulverlackes fest, d. h. der Mindestkonzentration eines Pulverlackes in Luft, bei der sich eine zündfähige Mischung ergibt. Das Verfahren basiert auf der Kenntnis des Brennwertes des Produktes, bestimmt nach ISO 1928, oder der Kenntnis der Brennwerte der Bestandteile des Produktes.
Aussagefähige Verfahren für die Messung dieser Größe erfordern spezielle Geräte, die schwer erhältlich sein können. Ein Verfahren zum Bestimmen der Explosionsindices von brennbaren Stäuben in Luft ist in ISO 6184 1 angegeben. Das Verfahren ist jedoch sehr kompliziert, erfordert beträchtliche Übung und ist teuer. Das Berechnungsverfahren ergibt untere Zündgrenzen, die bei der Anwendung auf Beschichtungs¬anlagen als zufrieden stellend gelten können.
ANMERKUNG 1   Bei nicht brennbaren Pulvern, z. B. auf Polyvinylchlorid Basis, kann das Verfahren trotzdem einen Wert für die untere Zündgrenze in Luft ergeben. Dadurch wird jede Unterschätzung eines Explosionsrisikos effektiv vermieden.
ANMERKUNG 2   Die in dieser Internationalen Norm angewendete Berechnung beruht auf folgenden Annahmen:
a)   Das Material liegt als Molekulardispersion vor.
b)   Es findet eine vollständige Verbrennung des Materials bis zur höchsten Oxidationsstufe statt.
c)   Es handelt sich um eine adiabatische Reaktion.
d)   Die Flammentemperatur für das Gemisch, mit dem die Mindestkonzentration für eine Explosion in Luft erreicht wird, beträgt
1 000 °C.

Poudres pour revêtement - Partie 4: Calcul de la limite inférieure d'explosibilité (ISO 8130-4:1992, Cor 1:1993 inclus)

Praškasti premazi - 4. del: Izračun spodnje meje eksplozivnosti (ISO 8130-4:1992, vključno s popravkom Cor 1:1993)

Ta del standarda ISO 8130 določa metodo izračuna spodnje meje eksplozivnosti praškastih premazov, tj. najnižjo koncentracijo praškastega premaza v zraku, pri kateri nastane eksplozivna mešanica. Temelji na poznavanju bruto kalorične vrednosti izdelka, ki se ugotovi z metodo iz standarda ISO 1928, ali na bruto kaloričnih vrednostih sestavin izdelka. Za zanesljivo merjenje te količine je potreben poseben aparat, ki morda ni takoj na voljo. Metoda določanja eksplozivnih kazalnikov vnetljivega prahu v zraku je opisana v standardu ISO 6184-1. Ta metoda je sicer zelo zapletena, zahteva precej strokovnega znanja in je tudi draga. Z metodo izračuna se dobijo spodnje meje eksplozivnosti, ki so se v praksi izkazale za zadovoljive pri uporabi v sistemih za nanašanje premazov.

This European Standard was approved by CEN on 16 October 2010.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same
status as the official versions.

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 Oh of the member
bodies casting a vote.
International Standard IS0 8130-4 was prepared by Technical Committee
lSO/TC 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: Cal&a tion of lower explosion limit
- Part 5: Determination of flow properties of a powder/air mixture
Part 6: Determination of gel time of thermosetting coating powders
-
at a given temperature
- Part 7: Determination of loss of mass on stoving
