In addition, the following definitions are applicable. 3.1.1 Batch 3.1 .I .I loomstate fabric for loomstate fabric, both a Production Batch and an Inspe
23、ction Batch are the quantity of fabric produced from one weavers beam or one continuously woven length not exceeding 5 O00 metres, provided that weft yarn of consistent and proven quality has been used If a fresh delivery of weft yarn of unproven quality is introduced during weaving the warp, a fres
24、h NOTE batch has been created. 3.1.1.2 piece treated fabric for piece treated fabric, both a Finishers Batch and an Inspection Batch are the quantity of fabric subject to finishing processes in one continuous length not exceeding 5 O00 metres If several small batches are brought together during the
25、finishing process to form one large NOTE Finishers Batch, due note should be taken of the need to maintain identification of each individual batch. 1) Published as AECMA Prestandard at the date of publication of this standard 2) In preparation at the date of publication of this standard 3) Published
