Note

Handling (Machining) :

  • During machining of the semi-finished products, evacuate swarf to prevent slipping or tripping hazard and observe the maximum allowable concentration of dust and
  • formaldehyde levels on the workplace which apply in your country.
  • Wear safety goggles during machining.

Storage:

  • The products shall be stored indoors in a normal environment (air at 10 - 30Ā°C / 30 - 70% RH) and kept away from any source of degradation such as sunlight, UV-lamps, chemicals (direct or indirect contact), ionizing radiation, flames, etc.
  • Dimensional changes (camber, warpage, shrinkage ā€¦) of the products as well as slight color shifts of the external surfaces can occur with time.
  • The latter does generally not pose a problem in case of semi-finished products since the surface-layer is mostly removed anyway upon machining them into finished parts.

Safety measures:

  • Standard industrial safety recommendations shall be observed.
  • Temperatures above 340 Ā°C shall be avoided.

X-ray Transparency

Transparency of the life science grades to high energy radiation (Measured at 23Ā°C on 12 mm thick test plates, applying radiation with an energy level of 59keV)

Radiation Resistance

Resistance of the life science grades to gamma radiation

  • Index 6 = 106Gy / 1MGy = 106Gy / 1 Gy = 100rad /
  • 100rad = 1J/kg / 1J/kg = 6.24.1012MeV/kg
  • X-rays energy ranging from 100eV to 100keV. Gamma radiation have energy greater than 100keV.
  • The Radiation Index (RI) is defined as the logarith, base 10, of the absorbed dose in Mega grays at which the flexural stress at break or flexural strain at break of the tested material is reduced to 50% of its original value, under specified conditions of irradiation (the most radiation-sensitive of these two properties is chosen as the reference critical property).
