Question

英文翻译~

1. A TOLERANCE +/-10PCT FOR EACH SIZE, TOTAL QUANTITY AND AMOUNT ACCEPTABLE. FOR SIZE XXX AND SIZE XXX EXTRA TOLERANCE +20/-10% ACCEPTABLE.
意思是：每个规格和总量不能超过+/-10%。不过规格XXX和规格XXX只要在+20/-10%范围内都可以接受
对吗？我怕语法或者单词上理解错误

2.其实这两句话后面还有一句：AN EXTRA SET OF DOCUMENT TO BE PRESENTED FOR SUCH QUANTITY.
‘SUCH QUANTITY'是不是属于开证不清晰？

3.我要告诉客户，请他CLARIFY THE MEANING OF 'SUCH QUANTITYA', 否则会造出开证不清晰。
那么‘开证不清晰’，英文怎么翻译比较准确？

1. 总量一定的情况下，单一型号货品可接受的误差在+/-10%之间。xxx和xxx型号货品的公差可在+20/-10%范围内；
2. 应该不算，因为它允许有误差的存在，只不过多了或者少了的部分要另附文件说明；
3. Please clarify the meaning of "such quantity" to avoid unnecessary confusing on L/C.

Answer 2

Each specification and total amount not more than + /-10%. But specifications XXX and specifications XXX + 20 /-as long as in the 10% range can accep
