Full title and description

ISO 1563:1990 — Dental alginate impression material. This International Standard specifies the classification, technical requirements and test methods for impression materials in powder form containing alginate as the gel‑forming ingredient (irreversible hydrocolloids) used for dental impressions.

Abstract

Specifies definitions, composition considerations, required properties (working/setting time, dimensional stability, detail reproduction, strength and tear resistance), sampling and test apparatus for alginate (irreversible hydrocolloid) dental impression powders. Figures in the standard illustrate test apparatus and components.

General information

• Status: Withdrawn (superseded by a consolidated hydrocolloid standard).
• Publication date: 1990 (Edition 2, published August/September 1990).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 11.060.10 — Dental materials.
• Edition / version: Edition 2 (1990).
• Number of pages: 10 pages (original publication).

Scope

Applies to alginate (irreversible hydrocolloid) dental impression materials supplied in powder form and intended to be mixed with water prior to use. The standard sets out classification, required properties, test methods and sampling rules for evaluating performance (e.g., working and setting times, dimensional change, detail reproduction and tear strength). It does not cover reversible hydrocolloid (agar) systems or non‑hydrocolloid impression materials, which are covered by other standards.

Key topics and requirements

• Classification of alginate impression powders by intended use and setting characteristics.
• Requirements for working time and setting time under specified test conditions.
• Dimensional stability and linear dimensional change limits after setting and storage.
• Tear strength and resistance to deformation during removal from the mouth or model.
• Detail reproduction criteria to ensure adequate capture of clinical features.
• Sampling, test apparatus illustrations and test procedures for reproducible laboratory evaluation.
• Labeling and information requirements (composition, powder‑to‑water ratio, storage and expiry guidance).

Typical use and users

Used by dental clinicians (general dentists, prosthodontists), dental laboratories and manufacturers for specification, quality control and conformity testing of alginate impression powders. Regulatory bodies and standards committees reference the standard when assessing hydrocolloid impression products.

Related standards

ISO 1563:1990 was consolidated into and replaced by ISO 21563:2013 (Dentistry — Hydrocolloid impression materials). Other related documents include earlier and parallel standards for agar and reversible hydrocolloid systems (e.g., ISO 1564 and ISO 13716) and regional/adopted editions (EN/LST adoptions).

FAQ

Q: What is this standard?

A: ISO 1563:1990 is an International Standard that specified requirements and test methods for dental alginate impression materials supplied in powder form (irreversible hydrocolloids).

Q: What does it cover?

A: It covered classification, composition considerations, working/setting times, dimensional stability, tear strength, detail reproduction, sampling and test apparatus for alginate powders.

Q: Who typically uses it?

A: Dental practitioners, dental laboratories, manufacturers of impression materials, test laboratories and regulatory/standards bodies for product specification and conformity assessment.

Q: Is it current or superseded?

A: Superseded — ISO 1563:1990 has been withdrawn and was consolidated into ISO 21563:2013 (Dentistry — Hydrocolloid impression materials). Users should refer to ISO 21563 (and any later revisions) for current requirements.

Q: Is it part of a series?
