Foreword 前言

This British Standard has been prepared under the direction of the Non-ferrous Metals Standards Committee. It is the second metric revision of BS 2874 , which was originally published in 1962 and subsequently revised in 1969 and it supersedes the 1969 edition, which is withdrawn. It is one in a series of standards for copper and copper alloys in various wrought forms, intended for general engineering purposes. The others in the series are:
该英国标准是在有色金属标准委员会的指导下制定的。这是BS 2874的第二次公制修订版，最初于1962年发布，随后于1969年修订，并取代了1969年版，该版已被撤回。它是用于一般工程目的的各种锻造形式的铜和铜合金的一系列标准之一。该系列中的其他作品包括：
BS 2870 Specificatıon for rolled copper and copper alloys : sheet, strip and foil
BS 2870 轧制铜和铜合金规格：板材、带材和箔材
BS 2871 Copper and copper alloys. Tubes
BS 2871铜和铜合金。管

In this revisıon, due regard has been given to the work of the international Organization for Standardization (ISO) and in particular to Technical Committee ISO/TC 26 . Copper and copper alloys, in respect of chemical compositions, testing requirements, properties and dimensional tolerances. Whenever possible and appropriate, the requirements of this standard have been aligned with those of corresponding international standards.
在本次修订中，对国际标准化组织（ISO）的工作给予了应有的重视，特别是对ISO/TC 26技术委员会的工作给予了应有的重视。铜和铜合金，关于化学成分、测试要求、性能和尺寸公差。在可能和适当的情况下，本标准的要求与相应的国际标准的要求保持一致。
Certain alloys that are considered to be in sufficient demand to warrant inclusion have been added. The additions are:
某些被认为有足够需求以保证纳入的合金已被添加。新增内容包括：
CZ 134 naval brass, high leaded
CZ 134 海军黄铜，高铅
CZ 135 high tensile brass, with silicon
CZ 135 高强度黄铜，含硅
CZ 136 manganese brass
CZ 136锰黄铜
PB phosphor bronze.
PB 荧光粉青铜。
The alloy previously known as CZ 123 in BS 2874 has been redesignated CZ 137 to avoid confusion with the similar but purer alloy which is included in BS 2870 and BS 2875.
以前在 BS 2874 中称为 CZ 123 的合金已重新命名为 CZ 137，以避免与 BS 2870 和 BS 2875 中包含的类似但更纯净的合金 混淆。
The demand for nine of the alloys included in the last edition of this standard is considered to be insufficient to warrant their retention and they have consequently been withdrawn. The alloys withdrawn are CA 103, CA 106, CZ 103, CZ 106, CZ 113, NS 102, NS 111, NS 112 and NS 113 .
对本标准上一版中包含的九种合金的需求被认为不足以保证保留它们，因此它们已被撤回。提取的合金有CA 103、CA 106、CZ 103、CZ 106、CZ 113、NS 102、NS 111、NS 112和NS 113。
In this revision, and for the purposes of this standard only, each of the alloys has been placed in one of three material groups, designated I, II and III, used to specify the dimensional tolerances in tables 5 to 9 . The tolerances specified have been reviewed in the light of current demand and practice. Account has been taken of ISO work when revising the tolerances and the break-points.
在本修订版中，仅就本标准而言，每种合金都放置在三个材料组之一中，分别命名为 I、II 和 III，用于指定表 5 至 9 中的尺寸公差。根据当前的需求和实践，对规定的公差进行了审查。在修改公差和断点时，已考虑 ISO 工作。
All mechanical properties have been reviewed and revised where appropriate. All bend test requirements have been deleted.
所有机械性能均已酌情进行审查和修订。删除了所有弯曲试验要求。
In previous editions of this standard, clauses have been included entıtled 'Inspection' and 'Facilities for testing'. As these clauses are contractual and not relevant to the standard for the product, they have been omitted from this revision.
在本标准的前几版中，已包含“检查”和“测试设施”条款。由于这些条款是合同条款，与产品标准无关，因此本次修订中省略了这些条款。
Compliance with a British Standard does not of itself confer immunity from legal obligations.
遵守英国标准本身并不赋予法律义务豁免权。

Should any of the test pieces fail the dezincification resistance test (see appendix G), two further samples from the same batch shall be selected for testing. One of these further samples shall be from the same length of rod, or section, as that from which the original failed test sample was taken. unless that length of rod or section has been withdrawn by the supplier.
如果任何试件未能通过抗脱锌测试（见附录G），则应从同一批次中再选择两个样品进行测试。这些进一步的样品之一应来自与原始未通过测试样品相同的杆或截面长度。除非供应商已撤回该长度的杆或截面。
Should both the further samples pass the dezincification resistance test, the batch represented shall be deemed to comply with the dezincification resistance requirements of this standard. Should either of the further samples fail the test, the batch represented shall be deemed not to comply with this standard.
如果两个进一步的样品都通过了抗脱锌测试，则所代表的批次应被视为符合本标准的抗脱锌性要求。如果其他样品中的任何一个未通过测试，则所代表的批次应被视为不符合本标准。
NOTE. If a batch of rods or sectıons or CZ 132 O conditıon faals the dezincification resistance test when retested, the supplier has the option to further heat treat the whole batch and resubmit the batch for all the tests called for on the order.
注意。如果一批棒材或棒材或 CZ 132 O conditıon 在重新测试时通过了抗脱锌性测试，供应商可以选择对整批产品进行进一步热处理，并重新提交该批次以进行订单中要求的所有测试。

Appendix C. The rounding of numbers rule
附录 C.数字四舍五入规则

For the purposes of determinıng compliance with compositional limits and mechanical properties (not dimensional tolerances), an observed value or a calculated value obtained from the analysis or test is rounded to the same number of decimal places as used in the relevant standard in expressing the specified limit. The following rules, based on those given in BS 1957, should be used for roundine
为了确定是否符合成分限值和机械性能（不是尺寸公差），从分析或测试中获得的观察值或计算值四舍五入到与相关标准中用于表示指定限值的小数点后位数相同。根据 BS 1957 中给出的规则，以下规则应用于 roundine
(a) If the figure immediately after the last figure to be retasned is less than five, the last figure to be retained should be kept unchanged.
（a） 如果紧接在最后一个要重新品尝的数字之后的数字少于5个，则保留的最后一个数字应保持不变。
(b) If the figure immediately after the last figure to be retanned is either greater than five, or equal to five and followed by at least one figure other than zero, the last figure to be retained should be increased by one.
（b） 如果紧接在最后一个要重新鞣制的数字之后的数字大于5，或等于5，其后至少有一个数字不是零，则保留的最后一个数字应增加1。
(c) If the figure immediately after the last figure to be retarned is equal to five and followed by zeros only. the last figure to be rotainod should be left unchanged if even and increased by one if odd.
（c） 如果紧跟在最后一个要延迟的数字之后的数字等于5，并且后面只有零。如果偶数，则轮状的最后一个数字应保持不变，如果为奇数，则增加 1。
