BS EN ISO 11246-2000 PDF

Full title and description

BS EN ISO 11246:2000 — Dental ethyl silicate bonded casting investments. This is the British (BS) / European (EN) adoption of ISO 11246 (originally published by ISO in 1996) and provides requirements and test methods for ethyl‑silicate‑bonded casting investments used in dental alloy castings.

Abstract

Specifies a method for assessing the efficacy of ethyl silicate bonded casting investments for dental casting alloy restorations. The standard sets out required physical properties and the methods for determining them (e.g., setting behaviour, dimensional change, strength and thermal performance) to ensure reproducible casting results in dental laboratories.

General information

• Status: Withdrawn / superseded (national/adopted BS/EN publication now withdrawn in favour of later consolidated standards).
• Publication date: BS EN ISO 11246 published 15 June 2000 (adoption of ISO 11246:1996).
• Publisher: British Standards Institution (BSI) as the UK adoption of the EN/ISO text; original International Standard published by ISO.
• ICS / categories: 11.060.10 — Dental materials / Prosthodontic materials.
• Edition / version: BS EN ISO 11246:2000 (adoption of ISO 11246:1996, edition 1).
• Number of pages: Approx. 12 pages for the BS/EN publication (original ISO 11246:1996 text was brief — approx. 5 pages).

Scope

Applies to ethyl‑silicate bonded casting investments used in dental casting of alloy restorations. The standard specifies the essential physical property requirements and the test methods for assessing those properties so that users and manufacturers can judge the suitability and performance of such investments for dental casting processes. (Note: the ISO text is concise and later consolidated standards expanded and replaced these requirements.)

Key topics and requirements

• Definition and classification of ethyl silicate bonded casting investments for dental use.
• Required physical properties and performance criteria (examples: setting behaviour, dimensional change on heating, compressive strength, refractoriness/thermal stability, and compatibility with casting alloys).
• Standardized test methods and sample preparation procedures for determining the specified properties and for evaluating investment efficacy in dental casting.
• Information and labelling requirements to accompany products (manufacturer instructions, recommended burn‑out procedures and intended use notes, where applicable).
• Context and relationship to later consolidated standards for casting investments and refractory die materials (see replacement/revision information).

Typical use and users

Used by dental laboratory technologists, dental materials manufacturers, quality and test laboratories, dental product regulators and standards bodies. Typical applications are product specification, incoming inspection, quality control of investments used for lost‑wax dental casting and supplier evaluation.

Related standards

ISO 11246 (1996) was later consolidated into and superseded by ISO 15912 (and its EN/ISO adoptions). Other related dental investment standards include ISO 7490 (gypsum‑bonded investments) and a set of ISO documents covering different bonding systems and refractory die materials; consult the consolidated EN/ISO 15912 series for the current, harmonized requirements.

FAQ

Q: What is this standard?

A: BS EN ISO 11246:2000 is the British/European adoption of ISO 11246 (original ISO publication 1996) covering ethyl‑silicate‑bonded casting investments for dental alloy castings; it specifies property requirements and test methods.

Q: What does it cover?

A: It covers the definition, required physical characteristics and laboratory test methods to assess the performance of ethyl‑silicate dental casting investments (e.g., setting, dimensional and thermal behaviour, and strength).

Q: Who typically uses it?

A: Dental laboratory technicians, manufacturers of dental investments, test laboratories, procurement and quality managers in dental product supply chains, and standards/regulatory bodies concerned with dental materials.

Q: Is it current or superseded?

A: The ISO 11246 text has been withdrawn and its content was consolidated into later standards (ISO 15912 and associated EN/ISO publications). The BS/EN adoption (BS EN ISO 11246:2000) is withdrawn/superseded by the later consolidated casting investment standards—consult EN/ISO 15912 (and its national adoptions) for the current requirements.

Q: Is it part of a series?

A: Yes — it belongs to the family of dental casting investment standards (covering different bonding systems and refractory die materials). The work on ISO 11246 was integrated into the broader ISO 15912 series which consolidates requirements for casting investments and refractory die materials.

Q: What are the key keywords?

A: Dental casting, ethyl silicate, investment material, refractoriness, dimensional change, setting, casting alloy compatibility, test methods.
