中文意思:
Thermal insulation of the loose-fill type shall be conditioned to a density as specified by the insulation manufacturer to obtain a required rated thermal resistance of Rsi 0.56 to 0.678 (R3.2 to R3.85).

流体灌注型的隔热材料应先作条件预处理，使其密度达到生产厂家的规格标准，这样才会具有所要求的额定阻热值 Rsi 0.56 to 0.678 (R3.2 to R3.85)。

19.16 Thermal insulation used for recessed temperature tests
19.16.1 Thermal insulation of the loose-fill type shall be conditioned to the density specified by the
insulation manufacturer to obtain a required rated thermal resistance of Rsi 0.56 to 0.678 (R3.2 to R3.85).
19.16.2 Thermal insulation shall be conditioned, if required, by a blowing or vacuum machine before it is
placed around the test luminaire. Density shall be verified by placing insulation into a box of known volume
and weight, and then weighing the filled box. The difference in weight between the empty and full box,
divided by the volume, shall be the insulation density.

5.18 Thermal insulation
5.18.1 Thermal insulation shall be fire-resistant material, such as glass fiber, inorganic material, or
polymeric material.
5.18.2 A polymeric thermal insulation material shall:
(a) have a temperature rating equal to or greater than the operating temperature in the
luminaire; and
(b) have a minimum HB flammability rating, or comply with the horizontal burning flame test of
Clause 16.25.
5.18.3 Thermal insulation shall be reliably secured in place. It shall be attached to the luminaire in the
correct position by at least one of the following means:
(a) staples or bolts;
(b) adhesive applied to at least one-third of the surface of the insulation;
(c) parts of the luminaire that do not have to be removed for installation. A supply conductor
projecting through the insulation is not acceptable for securing the insulation in place; and
(d) other means if investigated and found to be mechanically equivalent.
5.18.4 Thermal insulation shall not be located within 6.4 mm (0.25 in) of any opening for the connection
of conduit unless the insulation is attached to a cover or other part that will be removed when conduit is
being attached to the luminaire.
5.18.5 Glass fiber thermal insulation provided as an integral part of the luminaire shall have a minimum
density of 9.6 kg/m3 (0.6 lb/ft3).

我公司做测试经常用啊，主要是用来测试RECESSED LAMP（筒灯），至于照片，我找找看
