What is ISO 6101-1 - Zinc content in rubber about ?
ISO 6101-1 is the first part of the multi-series standard that specifies an atomic absorption spectrometric method for the determination of the zinc content of rubbers.
The method described in ISO 6101-1 applies to raw rubber and rubber products having zinc contents at a minimum of 0,05 % (mass fraction). Zinc contents below this limit can be determined, provided that suitable adjustments are made to the mass of the test portion and/or to the concentrations of the solutions used.
The use of the ISO 6101-1 addition method might lower the bottom limit of detection.
Who is ISO 6101-1 - Zinc content in rubber for ?
ISO 6101-1 on adhesives is relevant to:
- Manufacturers of rubber
- Chemical engineers
- Scientists and researchers
- Any entity responsible for testing and quality assurance of rubber
Why should you use ISO 6101-1 - Zinc content in rubber for ?
Rubber is a tough, flexible material, suitable for making tyres. Addition of zinc to rubber enhances the vulcanization properties of rubber. This is why zinc is a popular metal added to rubber.
ISO 6101-1 provides best practice guidance on methods and requirements for determining the zinc metal content present in raw rubber using atomic absorption spectrometry.
ISO 6101-1 specifies procedures, principles, reagents, sampling methods, and testing to determine the zinc concentration in a sample, as well as procedures for preparing standard calibration solution, tracking it on a calibration graph, and using spectrometric measurement to measure the zinc concentration.
Overall, ISO 6101-1 is a comprehensive guide to provide methods for determining the zinc metal content present in rubber, so users will gain a comprehensive understanding of the quality of rubber to improve durability and strength.
What’s changed since the last update ?
BS EN 6101-1:2019 supersedes BS EN 6101-1:1991, which is withdrawn and includes
- The procedure for the destruction of organic matter is further detailed
- Formula (2) in 9.2 has been changed to zinc content being expressed as milligram per kilogram
- Precision data have been updated in Annex B
