BS EN ISO 15854:2021

What is ISO 15854 about?  

ISO 15854 is one of a series of documents for Dentistry, Casting, and baseplate waxes that specifies the classification of and requirements for dental casting and dental baseplate waxes together with the test methods to be employed to determine compliance with these requirements 

ISO 15854 does not include specific and quantitative requirements for freedom from biological hazards. It is recommended that, in assessing possible biological or toxicological hazards, references be made to ISO 7405 and ISO 109931. 

Note: ISO 15854 does not apply to waxes supplied for additive manufacturing or CAD/CAM-based procedures. 

Who is ISO 15854 for? 

ISO 15854 is applicable to- 

• Manufacturers of Casting and baseplate waxes for dentistry use. 
• Dentist 
• Medical laboratories for dentistry purposes 

Why should you use ISO 15854? 

Casting wax is a mouldable material with minimal residue on ignition suitable primarily for shaping patterns in the production of cast restorations using the “lost-wax” technique, and baseplate waxes mouldable material primarily for forming occlusion rims, positioning and retaining artificial teeth therein, and shaping patterns that are duplicated in the denture base polymer. 

ISO 15854 helps manufacturers to meet minimum requirements for dental casting and dental baseplate waxes together with the test methods to assure the expected quality standards. 

What’s changed since the last update? 

BS EN ISO 15854:2021 supersedes ISO 15854:2005, which has been withdrawn. BS EN ISO 15854:2021 has some significant technical changes with respect to ISO 15854:2005, these include: 

• The requirement for separating paper for baseplate wax sheets has been revised 
• The statement of the requirement for residue on ignition for casting wax has been revised 
• The mass of wax used for the residue on the ignition test has been increased to 10g 
• The use of a mandrel for the delamination test has been revised 
• Clarification has been given on the procedural detail in most tests 
• Specification of the content of the required report has been added
