BS 3984:1982

What is BS 3984- Sodium silicates about?  

BS 3984  discusses specifications for sodium silicates. BS 3984 specifies requirements for the following materials of technical quality: 

• Sodium metasilicate pentahydrate (n) suitable for general industrial use 
• Sodium metasilicate pentahydrate (s) of selected quality, in respect of chloride and sulphate contents, which will meet British Government Services requirements 
• Sodium silicate solutions suitable for general industrial use 

The last specification comprises a method of classification for sodium silicate solutions, together 

with the permitted tolerances on the properties specified when ordering. 

Who is BS 3984- Sodium silicates for? 

BS 3984 on the specification for sodium silicates  is useful for: 

• Chemical manufacturers  
• Paint manufacturers  
• Fertilizers manufacturers  
• Soap and detergent manufacturers 
• Tar products manufacturers  
• Quality control personnel  

Why should you use BS 3984 - Sodium silicates?  

BS 3984 provides you with two specifications are given for sodium metasilicate pentahydrate. One covers a product suitable for general industrial use and is designated as sodium metasilicate pentahydrate (n) and the other includes additional requirements for material of selected quality in respect of chloride and sulphate contents, suitable for British Government Services use, and is designated as sodium metasilicate pentahydrate (s)1). 

BS 3984 provides you with a specification of a more general nature is given for sodium silicate solutions which take into account variability of composition. Sodium silicate glass is manufactured by fusing together sand and sodium carbonate. BS 3984 provides you with special requirements and guides you with the packaging and marking of the products. 

What’s changed since the last update?  

BS 3984:1982 supersedes BS 3984:1966, which is withdrawn. BS 3984:1982 includes some technical changes with respect to BS 3984:1966. These include: 

• The test methods are not appended to this revision but are published as Parts of BS 6092. In preparing BS 6092, the opportunity has been taken to implement those test methods prepared by Technical Committee 47, Chemistry, of the International Organization for Standardization (ISO) which have been prepared as a result of international collaboration in which the United Kingdom has participated. 
• The units for the specification values have been altered, where necessary, to conform with the expression of results in the associated revised test methods.
