Article 4 Credits v. Contracts 第四条 信用证与合同 a. A credit by its nature is a separate transaction from the sale or other contract on which it may be based. Banks are in no way concerned with or bound by such contract, even if any reference whatsoever to it is included in the credit. Consequently, the undertaking of a bank to honour, to negotiate or to fulfil any other obligation under the credit is not subject to claims or defences by the applicant resulting from its relationships with the issuing bank or the beneficiary. A beneficiary can in no case avail itself of the contractual relationships existing between banks or between the applicant and the issuing bank. a.就性质而言，信用证与可能作为其依据的销售合同或其它合同，是相互独立的交易。即使信用证中提及该合同，银行亦与该合同完全无关，且不受其约束。因此，一家银行作出兑付、议付或履行信用证项下其它义务的承诺，并不受申请人与开证行之间或与受益人之间在已有关系下产生的索偿或抗辩的制约。 受益人在任何情况下，不得利用银行之间或申请人与开证行之间的契约关系。 b. An issuing bank should discourage any attempt by the applicant to include, as an integral part of the credit, copies of the underlying contract, proforma invoice and the like. b.开证行应劝阻申请人将基础合同、形式发票或其它类似文件的副本作为信用证整体组成部分的作法。 Article 5 Documents v. Goods, Services or Performance 第五条单据与货物／服务／行为 Banks deal with documents and not with goods, services or performance to which the documents may relate . 银行处理的是单据，而不是单据所涉及的货物、服务或其它行为。 Article 6 Availability, Expiry Date and Place for Presentation 第六条有效性、有效期限及提示地点 a. A credit must state the bank with which it is available or whether it is available with any bank. A credit available with a nominated bank is also available with the issuing bank. a.信用证必须规定可以有效使用信用证的银行，或者信用证是否对任何银行均为有效。对于被指定银行有效的信用证同样也对开证行有效。 b. A credit must state whether it is available by sight payment, deferred payment, acceptance or negotiation. b.信用证必须规定它是否适用于即期付款、延期付款、承兑抑或议付。 c. A credit must not be issued available by a draft drawn on the applicant. c.不得开立包含有以申请人为汇票付款人条款的信用证。 d. i. A credit must state an expiry date for presentation. An expiry date stated for honour or negotiation will be deemed to be an expiry date for presentation. d. i信用证必须规定提示单据的有效期限。规定的用于兑付或者议付的有效期限将被认为是提示单据的有效期限。 ii. The place of the bank with which the credit is available is the place for presentation. The place for presentation under a credit available with any bank is that of any bank. A place for presentation other than that of the issuing bank is in addition to the place of the issuing bank. ii.可以有效使用信用证的银行所在的地点是提示单据的地点。对任何银行均为有效的信用证项下单据提示的地点是任何银行所在的地点。不同于开证行地点的提示单据的地点是开证行地点之外提交单据的地点。 e. Except as provided in sub-article 29 (a), a presentation by or on behalf of the beneficiary must be made on or before the expiry date. e.除非如29(a)中规定，由受益人或代表受益人提示的单据必须在到期日当日或在此之前提交。
