一字之差，相去千里？——灯具控制器烤箱材料探讨
关于IEC61347（GB19510）附录D烤箱与UL935烤箱材料，请看第一段话：IEC61347
D.1 Test enclosure
The heating tests are made in an enclosure in which the temperature of the ambient air is maintained as specified (see Figure D.1). The entire test enclosure shall be constructed of heat resistant material 25 mm thick.
GB19510翻译成耐热材料
再看UL935要求：
25.5 During the test the ballast is to be supported as described in 25.9 and as illustrated in Figure 25.1. The floor between the heaters and the ballast under test is to be of a thermal insulating material.
而根据UL935的要求，thermal insulating material是热绝缘材料，与耐热材料完全是两码事。
根据中英文字面来理解：
heat resistant material （耐热材料）可以是金属（导热材料，但不是热绝缘材料）、夹板（热绝缘材料）、石棉（热绝缘材料）。
thermal insulating material（热绝缘材料）则不可以是金属，但可以是夹板、石棉等材料。
有不同的观点吗？欢迎讨论。
确实是不对的，但是没人意识到这个问题，觉得有个烤箱就可以了 好吧，我一般认为有个烤箱就可以了。
烤箱的温度可以通过外部检测 一个概念，只是UL和IEC的表达风格不同。可统一翻译为“耐热材料”。 themaster 发表于 2014-8-6 13:35 http://bbs.angui.org/static/image/common/back.gif

你确定thermal insulating是耐热的意思吗？heat resistant我相信是。
thermal insulating我认为是隔热材料。
找到个例句，可以参考理解：
Rock wool insulation blanket with excellent thermal insulating properties, construction and installation convenience, energy saving effect is remarkable, and is of high performance to price.
岩棉保温毡具有优良的保温隔热性能，施工及安装便利、节能效果显著，具有很高的性能价格比。
thermal insulating 的确是隔热的意思，以前由于本人所接触的过产品局限，没见过这个个词出现在同一个标准中，所以统一翻译成“耐热材料”。
你说的很有道理：
heat resistant material如果翻译成“耐热材料”，则只定义材料的特性，即“耐热”。
thermal insulating material 如果翻译成“隔热材料”，则意味着材料本身不仅自身要”耐热“，而且启“隔热”作用。一般认为：这样以来“金属”由于传热很快，就不适合做“隔热”材料了（我不太清楚材料是怎么定义的，不知道这样说是不是准确）。
所以结合语境翻译可能更准确点。
你贴中的两个语境，我觉得可都翻译为“耐热材料”。

这个有点区别，是thermal insulation.
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). fasten 发表于 2014-8-6 16:37 static/image/common/back.gif
这个语境有何特别之处吗？
没什么特殊语境只是个人觉得：“The floor between the heaters and the ballast under test is to be of a thermal insulating material” only can see it says it's a kind of "thermal resistant" material, not see it has "insulating " function.
所以个人觉得翻译成“耐热材料”比较稳妥。
