UL1598温升测试天花|UL1993温升测试天花

UL1598温升测试天花是广东安规根据标准UL1598第19.10节及图19.10.1、UL1993图9.2及9.5.2节设计制作而成。UL测试天花带可活动支架与脚轮，可移动，可随意更换摆放位置，非常方便实验室进行日常测试与设备管理。

UL1598温升测试天花满足以下结构要求：

(1) 正面和背面为1218mm×1218mm，12mm厚的胶合板。

(2) 两边木料为2 x 6 in。
(3) 两端木料为1 x 6 in。

(4)内部支撑木料为2 x 4 in。
(5) 内装美国进口UL认证的标准4 x 1-1/2 in的8角形接线盒（俗称八卦板）。

注：目前中国市面上其他公司生产的大部分UL1598天花所使用的Outlet Box均为手工制作，非标准要求的Outlet Box，无UL认证或仿冒UL认证，本公司均为美国原装进口UL认证八卦板，直接从美国市面上购买所得。包括侧面的接线盒，均有UL认证，其他外行仪器商为国内随意寻找接线盒，完全不能达到标准要求，不能通过正儿八经的UL仪器设备审核。
(6) 接线包含一根白色和黑色的14AWG导线及一根16AWG或更粗的线接在接线盒上用于接地。
(7) 天花内垂直铺设两层约89mm厚的玻璃纤维，热阻值为Rsi 1.4到1.9，直接与八卦板接触并完全铺设于金属导线管周围。
(8) 测试天花底部至少距离地面1.8米，请保证测试房间层高至少达到2.3米左右，距离任意墙面或其他障碍物至少0.6米。

The UL1598 temperature test ceiling apparatus conforms to Figure 19.10.1 and is constructed as follows:
(1) the face and back are plywood 12mm thick, 1218 mm (48 in) square.
(2) the sides shall be 2 x 6 in trade size wooden members.
(3) the ends shall be 1 x 6 in trade size wooden members.

(4) the inside supports shall be 2 x 4 in trade size wooden members.
(5) a metal octagonal outlet box, 4 x 1-1/2 in trade size, shall be securely mounted in the center of the plywood panel, projecting through and flush with the outer face. One method of mounting the box is with steel angle brackets attached to opposite sides of the box and secured with wood screws to the inside of the plywood panel.

(6) wiring shall consist of one white and one black 14 AWG conductor of any type, and one 16 AWG or larger conductor, bonding the boxes together.

(7) the test ceiling apparatus is filled with two layers of faced or unfaced glass fiber insulation batts positioned at 90 degrees to each other. The insulation batts is approximately 89 mm (3.5 in) thick and Rsi 1.4 to Rsi 1.9 (R8 to R11), positioned directly in contact with the outlet box and slit to completely surround the flexible metal conduit.
(8) The test ceiling apparatus shall be mounted in a draft-free room, and shall be located not less than 1800 mm (72 in) above the floor, a minimum of 300 mm (12 in) below the room ceiling, and a minimum of 600 mm (24 in) from any wall or other obstruction.
