RheoCheck - Test Results
Below you can find the description of the test results produced by RheoCheck software
 

MI: Initial Torque ML: Minimum Torque tML: Time at Minimum Torque
This calculation returns the Maximum Torque recorded at Test Start.

REFERENCE STANDARD: ISO 6502-1, ISO 6502-3

UNIT: dN*m or Lbf*In

CALCULATION PARAMETERS:
Reference Curve (0=S*,1=S')
This calculation returns the minimum torque value measured during the test;

The calculation provides useful information regarding the viscosity of the green compound at test temperature.
For example, this information may be useful for:
- the correct evaluation of the force needed for injection moulding (depending from the shape of the mould and the size of the injection channels)
- the setting of temperature and force for extrusion process.

REFERENCE STANDARD: ISO 6502-1, ISO 6502-3

UNIT: dN*m or Lbf*In

CALCULATION PARAMETERS:
Reference Curve (0=S*,1=S')
This calculation returns the time, from the start of the test, when the ML point is reached (in the case of maintenance of the ML value over a period of time, it represents the termination point of the interval)

UNIT: mm:cc (minutes, minutes/100) or mm:ss (minutes, seconds) or Seconds

CALCULATION PARAMETERS:
Reference Curve (0=S*,1=S')
MH: Maximum Torque tMH: Time at Maximum Torque ts_x: Scorch Time
This calculation returns the maximum torque value measured during the established test time.

Depending from the product under test, from the test time selected and from the test temperature, the curve may have reached a plateau value or not
This calculation is an indication of the mechanical characteristics of the cured compound and has positive correlation with other mechanical properties like hardness and tensile stress at set strain.

REFERENCE STANDARD: ISO 6502-1, ISO 6502-3

UNIT: dN*m or Lbf*In

CALCULATION PARAMETERS:
Reference Curve (0=S*,1=S')
This calculation returns the time, from the start of the test, when the MH point is reached (in the case of maintenance of the MH value over a period of time, it represents the starting point of the interval)

UNIT: mm:cc (minutes, minutes/100) or mm:ss (minutes, seconds) or Seconds

CALCULATION PARAMETERS:
Reference Curve (0=S*,1=S')
The Scorch time tsx is the time required for the torque to increase by x units from ML. The typical value of x for an MD Rheometer is 1 dN•m.

The scorch time (time to incipient cure) tsx is a measure of the processing safety of the compound.
For injection moulding, it provides a relative indication of the maximum available time for the complete filling of the cavities.

REFERENCE STANDARD: ISO 6502-1, ISO 6502-3

UNIT: mm:cc (minutes, minutes/100) or mm:ss (minutes, seconds) or Seconds

CALCULATION PARAMETERS:
Reference Curve (0=S*,1=S')
t'_x: time to set percentage of curing M_x: torque at set percentage of curing Tanƌ@ML: Tangent of ƌ at Minimum Torque
The time to a percentage of full cure from minimum torque t’_x is the time taken for the torque to reach: ML + x*(MH-ML)/100
Frequently used values of t’_x are:
- t’_10: is a measure of the early stages of cure
- t’_50: provides the slope of the curve is greatest at this point.
- t’_90: is often used as an indicator of optimum press cure

REFERENCE STANDARD: ISO 6502-1, ISO 6502-3

UNIT: mm:cc (minutes, minutes/100) or mm:ss (minutes, seconds) or Seconds

CALCULATION PARAMETERS:
Percentage of Curing desired.
Reference Curve (0=S*,1=S')
Torque at a percentage of full cure from minimum torque M_x is the torque value at: ML + x*(MH-ML)/100

REFERENCE STANDARD: ISO 6502-1, ISO 6502-3

UNIT: dN*m or Lbf*In

CALCULATION PARAMETERS:
Percentage of Curing desired.

UNIT: dN*m or Lbf*In
tR_x: Time for Reversion of x dN*m Rev_t: Reversion at set Time MCR: Maximum Curing Rate
This calculation returns the time from test start, when a torque reduction of x dN*m from MH is detected.
The calculation is an expression of the degradation of the sample at the testing conditions.

UNIT: mm:cc (minutes, minutes/100) or mm:ss (minutes, seconds) or Seconds

CALCULATION PARAMETERS:
