How to Conduct Second-Source A/B Testing for Raw Rubber?
Quick AnswerCompare incumbent A and candidate B under identical sampling, formulation, and process conditions, and record results at three levels: raw rubber, compound, and finished article.
Sampling and Documentation
ISO 1795 specifies sampling and test-piece preparation methods for raw rubber bales. Each testing program shall record factory, batch number, sampling time, retained-sample location, pre-mixing treatment, and operator.
Comparison Dimensions
At the raw-rubber level, assess Mooney viscosity, P0/PRI, and other contract specifications; during compounding, evaluate the process window, dispersion, and vulcanization; for the finished article, check customer-specified dynamic or static properties and durability. A single passing result only reflects that specific sample.
