- Quality control department
Why should you use BS 5881- Grammage of single layers of solid fibreboard?    
Grammage is the density of fiberboard which is expressed in grams per square meter (g/m2). Grammage has great significance both to the consumer and the producer in defining price. The values of many physical properties such as bursting strength, thickness, and bulk are interpreted and specified with regard to grammage.
BS 5881 describes a laboratory method for determining the grammage of single layers of glued and laminated solid fibreboard. BS 5881 covers reagents and materials, procedure, expression of result, and test report. This can help to determine many physical properties such as bursting strength, thickness, and bulk are interpreted and specified with regard to grammage.
