BS ISO 19984-1:2017 Rubber and rubber products. Determination of biobased content - General principles and calculation methods using the formulation of the rubber compound, 2017
- National foreword
- Foreword
- Introduction
- 1 Scope
- 2 Normative references
- 3 Terms and definitions
- 4 Principle
- 4.1 Identification indices for rubber or a rubber product to determine the biobased content
- 4.2 Condition level 1: when all (a), (b) and (c) are available
- 4.3 Condition level 2: when (a) is available but (b) and/or (c) is unavailable
- 4.4 Condition level 3: none of (a), (b) nor (c) is available
- 4.5 Distinction between biobased carbon content and biobased mass content
- 4.6 Principle of determination of the biobased content by analyses
- 4.7 Outline of analyses and separation procedures for the determination of biobased contents
- 5 Calculation methods for biobased content
- 5.1 Constituents of a rubber product
- 5.2 Biobased mass content
- 5.2.1 Biobased mass content when the biobased constituents are derived wholly from biomass
- 5.2.2 Biobased mass content when the biobased constituents are derived partly from biomass
- 5.3 Biobased carbon content
- 5.3.1 Biobased carbon content when the biobased constituents are derived wholly from biomass
- 5.3.2 Biobased carbon content when the biobased constituents are derived partly from biomass
- 6 Test report
- Annex A (informative) Difference between “biobased carbon content” and “biobased mass content”
- Annex B (informative) Mechanism of 14C insertion into biobased products
- Annex C (informative) Examples for calculation of biobased mass content and biobased carbon content
