(j) Upper lower flammability or explosive limits

Other physical or chemical parameters in addition to those listed above may also be included in this section of the SDS.

This may lead to symptoms of hyperviscosity syndrome.

A4.3.9.2 In the case of a mixture, the entries should clearly indicate to which ingredient the data apply, unless it is valid for the whole mixture.

A4.3.9.1 Describe the empirical data of the substance or mixture (if possible) in this section.

In particular, the Reynolds number (which compares the effect of momentum of a fluid to the effect of viscosity) can become very low.

A4.3.12.1 Provide information to evaluate the environmental impact of the substance or mixture if it were released to the environment. This information can assist in handling spills, and evaluating waste treatment practices and should clearly indicate species, media, units, test duration and test conditions. Where information is not available this should be stated. Provide also a short summary of the data given under A4.3.12.3 to A4.3.12.7.

Information on toxicity can be provided using data from tests performed on aquatic and or terrestrial organisms. This should include relevant available data on both acute and chronic aquatic toxicity for fish, crustaceans, algae and other aquatic plants. In addition, toxicity data on other organisms (including soil micro and macro organisms) such as birds, bees and plants, should be included when available.

This process happens typically within a minute for temperatures about 50 K above the melting temperature or glass transition temperature, even for highly viscous polymers, such as, for instance, polytetrafluoroethylene, and this holds even for pores with an aspect ratio as large as 10,000.

A4.3.12.2 Some ecotoxicological properties are substance specific, i.e. bioaccumulation, persistence and degradability. The information should therefore be given, where available and appropriate, for each substance of the mixture.

Bioaccumulation is the potential for the substance or certain constituents of a mixture to accumulate in biota and, possibly, pass through the food chain. Test results relevant to assess the bioaccumulative potential should be given. This should include reference to the octanol water partition coefficient (Kow) and bioconcentration factor (BCF), if available.
