Viscosity & Flash Point Standards
Certified Viscosity Check Oils
ASTM D445, ASTM D5293, ASTM D4684
CANNON certified viscosity check oils verify SAE target viscosities for kinematic viscometers, cold-cranking simulators and mini-rotary viscometers per ASTM D445, D5293 and D4684 respectively. Each check oil contains a commercial engine oil with certified values at common blend target values for density in g/cm³ (g/mL) at 15 °C, kinematic viscosity in mm²/s (cSt) at 40 °C and 100 °C as well as cranking and pumping viscosities in mPa∙s (cP) at SAE J300 specification temperatures. CANNON certified viscosity check oils are available in 1 L (quart) and 3.8 L (gallon) sizes.
Flash Point Reference Materials
ASTM D56, ASTM D92, ASTM D93
CANNON flash point reference materials are produced in accordance with ASTM D56, Tag Closed Cup Flash Point, ASTM D92, Cleveland Open Cup Flash Point and ASTM D93, Pensky Marten Closed Cup Flash Point. Lot specific data including average flash point and observed standard deviation from a statistical analyis of 40 tests in 20 different laboratories is provided with each standard. Flash Point Reference Materials are sold in 200 mL bottles.
Flow Cup Viscosity Standards
ASTM D4212, ASTM D1200
CANNON flow cup viscosity standards are for use in Zahn, Shell and Ford flow cups. Lot specific kinematic viscosity data in mm²/s (cSt) and calculated cup drain times are provided with each standard. Nominal values at 25 °C are shown in the associated table. Data is also provided at 20 °C and 23 °C.
High Temperature (HTHS) Viscosity Standards
ASTM D4683, D4741, D5481, D6616
CANNON high temperature viscosity standards are produced in accordance with ASTM D5481, Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer and ASTM D4741, Viscosity at High Temperature and High Shear Rate by Tapered Plug Viscometer. ASTM D6616 TBS tet at 100 °C applies to certain standards as well. Lot specific viscosity data in mPa·s (cP) is provided with each standard.
High Viscosity Standards
ASTM D2170, ASTM D2171
CANNON high viscosity standards cover viscosity ranges of particular interest for asphalt and polymer viscosity determinations. See ASTM D2170, Kinematic Viscosity of Asphalts (Bitumens) and D2171, Viscosity of Asphalts by Vacuum Capillary Viscometer. Lot specific kinematic viscosity data in mm²/s (cSt) and dynamic viscosity data in mPa·s (cP) is provided with each standard as appropriate.
Low Temperature Viscosity Standards (General, CCS and CMRV)
ASTM D2983, ASTM 3829, ASTM 4684, ASTM 5293, ASTM D6821, ASTM D6896, SAE J300
CANNON low temperature viscosity standards verify viscometer performance at sub-zero temperatures. These standards are applicable to SAE Specification J300 as well as a variety of ASTM methods including ASTM D2983, Low-Temperature Viscosity of Lubricants Measured by Brookfield Viscometer, ASTM D3829, Predicting the Borderline Pumping Temperature of Engine Oil, ASTM D4684, Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature, ASTM D6821, Low Temperature Viscosity of Drive Line Lubricants in a Constant Shear Stress Viscometer, ASTM D6896, Determination of Yield Stress and Apparent Viscosity of Used Engine Oils at Low Temperature and ASTM D5293, Apparent Viscosity of Engine Oils and Base Stocks Between –5 °C and –35 °C Using Cold-Cranking Simulator.
Silicone Viscosity Standards for Rotational Viscometers
CANNON silicone viscosity standards are intended for use with rotational viscometers only. Silicone viscosity standards are not recommended for glass capillary viscometers (including vacuum viscometers), metal cup-type viscometers (such as ISO, Zahn, Ford and Shell cups), or any other viscometers providing kinematic viscosity—CANNON hydrocardon-based oil standards should be used for these types of viscometers.
CANNON silicone viscosity standards are specifically formulated for use with rotational viscometers. Lot specific viscosity data in mPa·s (cP) at 20 °C, 23 °C, 24 °C, 25 °C, 26 °C, 27 °C and 40 °C is provided with each standard. Viscosity standards are sold in 500 mL bottles.
Thomas®-Stormer® Viscosity Standards
Thomas-Stormer viscosity standards calibrate manual and electronic Thomas-Stormer viscometers. The KREBS UNIT (KU) is often used for Thomas-Stormer viscometers. Lot specific viscosity data (in cP and KU) is provided with each standard at 23 °C, 24 °C, 24.5 °C, 25 °C, 25.5 °C and 26 °C.
