客人要求網(wǎng)絡(luò)線要能防UV(紫外線),想問(wèn)一下要用什么對(duì)應(yīng)的標(biāo)準(zhǔn)?
知道電源線或UL1581中的一個(gè)Sunlight resistant(耐日光測(cè)試),具體是用carbon-arc exposure or xenon-arc exposure(碳弧或氙弧測(cè)試)
請(qǐng)問(wèn)Sunlight resistant(耐日光測(cè)試)是不是防UV(紫外線)測(cè)試。不是的話要用什么標(biāo)準(zhǔn)?
謝謝!

7.22 Sunlight resistant test
Any cable that is marked for sunlight-resistant use as described in Clause 8.3.8 shall be considered
acceptable for use in sunlight if the ratio of the average tensile strength and ultimate elongation of five
conditioned specimens of the overall jacket to the average tensile strength and ultimate elongation of five
unconditioned specimens of the overall jacket is 0.80 or more, when the finished cable is conditioned and
tested in accordance with the Weather (Sunlight) Resistance Test in CSA C22.2 No. 2556 or UL 2556,
using 720 h of carbon-arc exposure, or xenon-arc exposure.
UL444要求的測(cè)試,可參考UL2556
