REPORTING FORMAT FOR THE CATEGORY APPROACH
see attached category document
PM_Lower Alkyl (C1-C8) Methacrylates
This is a category (C1-C8 lower Alkyl Methacrylates) with clear trends in the physicochemical properties of its members, related to molecular weight, molecular size and hydrophilicity.

Qualifier:

according to guideline

Guideline:

other: • DIN 51562 Parts 1 – 4 • ISO 3104 • Standard operating procedures (QS-PA/AP-0107) • Equipment calibration procedures (QS-VPÜ/AP-097)

GLP compliance:

yes

Type of method:

other: viscometer

Key result

Temp.:

20°C

Parameter:

kinematic viscosity (in mm²/s)

Value:

2.12

The kinematic viscosity of the test item was measured with a micro-Ubbelohde viscometer according to DIN 51 562 at 20°C and 40°C as preferred by the OECD Guideline 114 (“Viscosity of Liquids”)

Kinematic viscosity at 20°C : 2.12 mm²/s

Kinematic viscosity at 40°C : 1.46 mm²/s

Conclusions:

In a valid guideline study the Kinematic viscosity at 20°C= 2.12 mm²/s.

Executive summary:

In a valid guideline study the Kinematic viscosity at 20°C = 2.12 mm²/s.
