交貨長度 Delivery length
1、絞線的交貨長度應符合表中規定。任一絞線的交貨長度允許偏差為±5%。每一合同的總交貨量中,允許有5%不小于三分之一標準交貨長度的短段交貨。根據雙方協議,允許以任何長度的短段交貨。
The delivery length of stranded conductors shall be as stipulated in the tables.The allowed tolerance for delivery length of any strands is within 5%.With the amount of short strands being 5% of the total length signed in the contract .the length for each short strand shall be not less than 1/3 of the standard delivery one.The delivery length can be decided through negotiation by both sides
2、絞線應成盤交貨,并妥善包裝。外段絞線允許成圈交貨,每圈至少包扎三處,并妥善包裝。
The strands shall be delivery in drum and packed carefully .The short strands shall be deliveried in coiling and tied up at least three points and packed carefully.
六、訂貨須知 Ordering Information
訂貨時,用戶應注明所訂產品的型號、規格、數量及產品所執行的標準等。
Please indicate the type、size、number and product standard when ordering .
