16 cfr 1500.44燃烧测试
1500.44里没有豁免string,ASTM F963-08 A4 豁免了string,请问别人申请做1500.44,我需要豁免它吗？谢谢 楼主提出的问题，确实太精僻，但A4只是对材料、产品或组件的定义进行了详细描述，并没有说要豁免，而其中还有一个附加燃烧测试，你可以再往下看下A5，参考16cfr1610的燃烧测试标准。故你不能豁免string. 谢谢valley01的回答,就是我还是有点疑问,没搞明白......这是ASTM F 963-08 A4对string的定义:
A4.2.5 strings—long slender flexible material usually consisting
of several strands (as of thread or yarn) woven or
twisted together, usually used to bind, fasten, tether, or tie. This
does not include string when used, for example, for hair on a
doll.
下面是豁免的条款:
A4.3 Exemptions
A4.3.1 Strings, paper, and ping-pong balls.
不明白valley兄说的没有豁免string是什么意思呢?我也再去看看1610..不知道能不能把1610的相关条款贴上来看看吗?....谢谢 Annex 4
Revised editorially to help clarify existing requirement
修改了一些表达方式, 帮助更清楚地解释存在的要求
Added a reference to the methodology from 16CFR1500.44
增加了参考16CFR1500.44测试方法的参考文献
Removed “may” and “should” and replaced with mandatory language “is” and “shall”
删除了“可能”和“或许”取而代之的是强制的语气“是”和“应该”
Added the following caveat 增加了下面说明:
“this standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.
此标准目的是测量和描述材料,产品或者组件在特定条件下对热和火的反应, 其并不包括材料,产品或者组件在真实火源中进行火灾风险评估所需的所有要素.”
Add definition of “paper” which is exempted from the flammability test
增加了对可以豁免燃烧测试的“纸”的定义
a thin, flat, single layer of material produced by the compression of fibers. The fibers are usually composed of cellulose. Examples of paper products are traditional playing cards, newspaper, magazines, and construction paper. Examples of products that are not paper are cardboard, and paperboard (multiple layers of paper bonded together).
由压缩纤维制成的薄的,平的单层. 此压缩纤维通常含有塞璐璐. 纸制产品例如传统的游戏牌,报纸,杂志和美术纸. 非纸制产品例如硬纸板和纸板(由多层纸粘结在一起形成). 以上是公证行的理解 谢谢valley01的回答，非常好，不知道velley的意思是不是由于公证行认为绳子并没有被豁免，所以要当纺织品来烧呢？还是什么其他意思？我确实还是没有搞明白为什么绳子不能被A4豁免．．．．另外我现在的问题是1500.44，不是1610，不知是不是valley看错了呢？谢谢
1.ASTM F963 08 A4里已经明确豁免了用于绑，固定，栓，系作用的细长的柔软的材料编制或搓在一起，但不包括已经被使用的绳子，比如玩偶上的头发．
A4.2.5 strings—long slender flexible material usually consisting
of several strands (as of thread or yarn) woven or
twisted together, usually used to bind, fasten, tether, or tie. This
does not include string when used, for example, for hair on a
doll.
下面是豁免的条款:
A4.3 Exemptions
A4.3.1 Strings, paper, and ping-pong balls.
2. A4.4Sample Preparation for solids and soft toys.
A4.4.2 Remove all string or paper from the product as deemed necessary.
3. 根据以上两点我不明白公证行对A4的理解里怎么会没有string的豁免呢？
4. 我的看法是string是固体，并不屬於A5或者1610的范围之内呀,不清楚valley让我看A5和1610的目的． 首先我们要搞清楚物体存在的几种状态:液态,气态,固态,冰水混合态
string 肯定是固态,但FABRIC也是固态,
STRING可以由不同的材料组成,也可以是FABRIC组成,
A4只是固体的燃烧测试,豁免了STRING,并给出了STRING的定义
A5是针对FABRIC燃烧测试,但没豁免STRING,
至于STRING做不做燃烧测试那得看STRING的材质,大小,
所以1500.44里没有豁免string
以上仅为个人理解 谢谢valley和nick的热情答复，一下子帮助我解决了很多让我困惑一时的问题，能不能举点具体的例子让我参考一下呢？再次感谢论坛上各位朋友的帮助．．．．． 不好意思，我看错了，应该是这样的，你再看下标准吧 Valley,謝謝你的幫助，但其實上面我也已經貼過很多遍了呀，A4.2是DEFINITIONS
A4.3是Exemptions．．．
A4.3Exemptions:
A4.3.1 Strings, paper, and ping-pong balls.
