accordance with 3.4.5, the adhesive shall have a glass transition temperature
not less than +85 °C.
3.4.10 Index of refraction (see 4.6.9).
The adhesive shall have an
index of refraction not less than 1.500.
3.4.11 Coefficient of linear thermal expansion (see 4.6.10). When
cured in accordance with 3.4.5, the adhesive shall-6have a coefficient of
linear thermal expansion not greater than 110 x 10 mm/°C.
3.4.12 Temperature (see 4.6.10). When cured in accordance with 3.4.5,
and after exposure to non-operating temperature extremes between -40 °C and
+85 °C, the adhesive shall meet the requirements of 3.4.11 when exposed to
operating temperature extremes between -28 °C and +85 °C.
3.4.13 Water absorption (see 4.6.11). When cured in accordance with
3.4.5, the adhesive shall absorb an amount of water not greater than 0.5

3.4.16 Connector compatibility (see 4.6.14). The adhesive shall
securely hold an optical fiber within a fiber optic connector. The adhesive
shall restrict axial movement of the optical fiber to less than ±0.2 µm with
respect to the fiber optic connector ferrule.
3.4.17 Outgassing (see 4.6.15) (space applications only). The cured
adhesive shall have a total mass loss (TML) of < 1 percent and a collected
volatile condensable material (CVCM) of < 0.1 percent.
3.5 Shipping. Adhesive material shall not be shipped on any order to
this specification if the shipping date is greater than 90 days from the
manufacturing date.
