- RSL test results stay valid for one year after the initial testing date or from the date which the formulation changed; whichever comes first.
- No change to a formulation is allowed once a RSL ‘PASS’ has been received for a material, without a re-test. A change of formula is defined as where there is a change of a chemical ingredient or where there is a change of a proprietary ingredient, where the composition of that ingredient is not known. A change of supplier of a chemical ingredient is allowed as long as the new supply is chemically identical to the old.
