Bedeutung und Verwendung
4.1 This guide provides a useful summary of procedures for selecting and using test paint powders and powder coatings. It is suitable for thermoplastic and thermosetting coatings unless otherwise stated. By design, this guide is not intended to address test methods or procedures developed specifically for the functional powder coating market, d.h., those powder coatings for pipes or reinforced steel bars (rebar). Information on current testing procedures for pipe and reinforced steel coating powders and powder coatings is available through their respective ASTM subcommittees A01.05 and D01.48.

4.2 Choosing the method to follow and the interpretation of the results will need to depend on the experience and requirements of each case, as well as the agreement between the buyer and the seller. It should be noted that many of the methods used to characterize paint powders, such as gel time (section 16) and inclined flow (Abschnitt 17), are primarily used for the relative comparison of two paint powders rather than giving test values that can be interpreted as good or bad. Interpretation of test results will depend on the specific application in question and often also on the chemical properties of the paint powder used.

Reichweite
1.1 This guide covers the selection and use of procedures for testing paint powders and powder coatings. Tisch 1 lists the included test methods. If more than one test method is listed for the same feature, no attempt is made to show that one method is superior to the other. Choosing the method to follow needs to depend on the experience and requirements of each case, as well as the agreement between the buyer and the seller.

1.2 This guide also references methods developed specifically for the coating powder industry by the Powder Coatings Council (PCI) and the International Standards Organization (ISO).

1.3 This guide describes the testing of paint powders by electrostatic spraying, fluidized bed or any other applicable method.

1.4 In SI-Einheiten ausgedrückte Werte gelten als Standardwerte. In dieser Norm sind keine anderen Maßeinheiten enthalten.

1.5 Dieser Standard soll nicht alle ansprechen, wenn überhaupt, Sicherheitsbedenken im Zusammenhang mit seiner Verwendung. Es liegt in der Verantwortung der Benutzer dieser Norm, vor der Verwendung geeignete Sicherheits- und Gesundheitspraktiken festzulegen und die Anwendbarkeit behördlicher Beschränkungen zu bestimmen.

1.6 Dieser internationale Standard basiert auf den international anerkannten Standardisierungsgrundsätzen, die in der Entscheidung über Grundsätze für die Entwicklung internationaler Standards festgelegt sind, Leitlinien und Empfehlungen des WTO-Ausschusses für technische Handelshemmnisse.
