Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
According to ECHA Guidance on information requirements and chemical safety assessment viscosity is relevant only to liquids. Viscosity is the property of a fluid substance of absorbing a stress during deformation which depends on the rate of the deformation. Similarly, the stress can be regarded as the cause which brings about a deformation rate. The viscosity of fluids is environmentally relevant owing to the penetration of fluids into the soil and the harmful effect on the groundwater which may thus possibly be caused. (Guidance on information requirements and chemical safety assessment - Chapter R.7a: Endpoint specific guidance)
Sulphuric acid, compound with graphite is an inorganic solid, consisting of natural graphite and variable amounts of intercalated sulphuric acid.
Since sulphuric acid, compound with graphite is a solid, testing of viscosity is technically not feasible and scientifically not justified according to ECHA Guidance on information requirements and chemical safety assessment.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
