Full title and description

St ISO 15912-2016 — Dentistry — Refractory investment and die material. This International Standard specifies requirements, classification and test methods for dental casting, brazing and pressable-ceramic investment materials and for refractory die materials used in dental laboratories, including marking, labelling and instructions for use.

Abstract

ISO 15912:2016 provides requirements and test procedures to determine the conformity of dental refractory investment and die materials regardless of binder or refractory composition. The standard classifies products into Types (by intended use) and Classes (by manufacturer‑recommended burn‑out procedure) and sets out essential physical and mechanical property requirements and associated test methods; it also includes requirements for packaging information and labelling.

Scope

Applies to dental casting investments, dental brazing investments, pressable‑ceramic investments and refractory die materials used in dental laboratories. The standard is independent of the refractory powder or binder chemistry and covers classification by intended use and by recommended burn‑out procedure, specification of essential physical and mechanical properties, test methods to determine conformity, and requirements for marking, labelling and manufacturer's instructions. Note: a specific quantitative requirement for setting expansion is not given; if setting expansion for gypsum‑bonded investments is measured, ISO 6873 (gypsum products) may be used as the referenced procedure.

Key topics and requirements

• Classification of products into Types (intended use) and Classes (burn‑out procedure).
• Specification of essential physical and mechanical properties (e.g., strength, thermal behaviour, dimensional change where applicable).
• Standardized test methods to determine conformity to the specified properties.
• Requirements for marking, labelling and manufacturer's instructions to accompany products.
• Guidance on applicability of particular requirements when binder chemistry or intended application makes certain tests irrelevant.
• Reference to related test procedures (for example, ISO 6873 for gypsum‑bonded investment setting expansion measurements).

Typical use and users

Used by dental materials manufacturers, dental laboratories, quality managers, product conformity assessors and standards committees. It supports product specification, internal quality control, third‑party testing and regulatory or procurement requirements where conformity of refractory investment and die materials must be demonstrated.

Related standards

Relevant related standards include ISO 6873 (Dentistry — Gypsum products) for procedures referenced when measuring setting expansion of gypsum‑bonded investments; earlier editions and amendments of ISO 15912 (for historical comparison) and other ISO/TC 106 standards covering dental materials and test methods.

FAQ

Q: What is this standard?

A: ISO 15912:2016 is an International Standard that specifies requirements, classification and test methods for refractory investment and die materials used in dentistry (dental casting, brazing and pressable‑ceramic investments and refractory die products).

Q: What does it cover?

A: It covers classification by intended use and burn‑out procedure, essential physical and mechanical property requirements, test methods to assess conformity, and requirements for marking, labelling and instructions for use. It does not mandate a single quantitative setting‑expansion requirement for all binder chemistries; where gypsum‑bonded investments are tested for setting expansion, ISO 6873 is the referenced procedure.

Q: Who typically uses it?

A: Manufacturers of dental investment and die materials, dental laboratories, test laboratories, certification bodies, procurement specialists and regulators concerned with dental material conformity and performance.

Q: Is it current or superseded?

A: ISO 15912:2016 (Edition 2) is the current edition published in January 2016; the ISO record indicates the publication was reviewed and confirmed (i.e., remains current as the reviewed edition). Users should verify on the ISO catalogue or their national standards body for any updates after 2016 before relying on it for compliance decisions.

Q: Is it part of a series?

A: It is part of the portfolio of dentistry standards maintained by ISO/TC 106/SC 2; it relates to other dental materials standards (for example ISO 6873 for gypsum products) and replaces earlier editions/amendments of ISO 15912 (2006 and its amendment).

Q: What are the key keywords?

A: dental investment, refractory die, casting investment, brazing investment, pressable‑ceramic investment, burn‑out class, test methods, labelling, dental materials (ICS 11.060.10).
