What is ISO 506 about?
ISO 506 discusses natural and concentrated rubber latex. ISO 506 specifies a method for the determination of the volatile fatty acid number of natural rubber latex concentrate. The method is only suitable for latices from Hevea brasiliensis.
Note: ISO 506 is not applicable to compounded latex, vulcanized latex, artificial dispersions of rubber or synthetic rubber latices.
Who is ISO 506 for?
ISO 506 on determining volatile fatty acid number in rubber latex is useful for:
- Rubber industries
- Chemical analysts
- Research and development team
- Quality control personnel
Why should you use ISO 506?
The volatile fatty acid number is one of the parameters for measuring the quality latices from Hevea brasiliensis. The method used to determine volatile fatty acid number is complicated, time-consuming and requires well-trained chemical analysts.
ISO 506 provides you with a detailed account of the method for determining the volatile fatty acid number in natural and concentrated rubber latex. The method described in ISO 506 is trusted in the rubber industry and is the choice of the industry experts for determining the volatile fatty acid number.
