EN 16732:2015 (E) 5 European foreword This document (EN 16732:2015) has been prepared by Technical Committee CEN/TC 248 “Textiles and textile products”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2016, and conflicting national standards shall be withdrawn at the latest by June 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16732:2015 (E) 6 Introduction The different types of slide fasteners are defined by the material of the elements (teeth), which form their slide fastener chains. They can be of metallic, moulded plastic or monofilament plastic construction. Metallic elements can be produced from flat or profiled wire and are usually clamped around the edge of a beaded tape. An alternative approach is to cast metallic elements directly onto such a tape. Similarly, plastic elements can be moulded onto a beaded tape. Such cast or moulded elements might have projections on which the slider operates to reduce abrasion of the tape. Plastic coil slide fasteners have polyamide or polyester monofilaments that are wound into coils to form engaging elements. The coils can be attached to the face of flat tapes by sewing. Alternatively, the coils can be woven or knitted into the tapes as they are constructed. Monofilament plastic elements can also be of the meander type, which straddle the tape edge. Typical slide fastener chain types are shown in Figure 1. SIST EN 16732:2016

EN 16732:2015 (E) 8 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 slide fastener (zip) fastening device consisting of two flexible, interlocking stringers, with or without end stops, and one or more sliders so arranged that by moving the slider along the stringers in one direction an opening is formed, and by moving it in the other direction the opening is closed 3.2 stringer tape with an attached row of elements designed to interlock with a row similarly attached to another tape 3.3 tape narrow fabric to which elements are fitted 3.4 element (tooth) engaging component fixed to the edge of the tape (see Figure 2) 3.5 slider moving component consisting essentially of a slider body and, normally, a puller which opens or closes the slide fastener by separating or engaging the single elements of the stringer Note 1 to entry: The slider might incorporate a locking device. Alternative slider types are available with a flip-over puller or double pullers, to facilitate operation from both front and back sides. 3.6 slider body component that joins or separates the elements when sliding along the two stringers of slide fastener 3.7 puller fitting attached to the slider body to facilitate manipulation 3.8 locking device device incorporated in the slider unit restricting its free movement along the slide fastener length in an opening direction Note 1 to entry: The locking device might operate either automatically on release of the puller or by manual pressure on the puller. 3.9 slide fastener length distance from the top of the slider to the bottom of the bottom stop, or box in the case of an open-end slide fastener, measured with the slider in the top position and with the puller in the downward position (see Figure 2) Note 1 to entry: Some suppliers measure the effective length of slide fasteners from the top of the slider to the bottom edge of the tape, especially in the case of two way open-end slide fasteners. SIST EN 16732:2016
EN 16732:2015 (E) 9 3.10 bottom stop stop at the bottom end of the chain that checks the opening movement of the slider Note 1 to entry: See Figure 2a), (Key n. 5). 3.11 top stop stop(s) at the top end of the chain that check(s) the closing movement of the slider 3.12 chain continuous closure formed by two interlocking compatible stringers Note 1 to entry: See Figure 2a), (Key n.8). 3.13 chain width width across the interlocked elements or shoulder on which the slider runs, whichever is the greater Note 1 to entry: See Figure 2b), (Key n.6). 3.14 bottom end end which is adjacent to the slider when the device is fully open 3.15 top end end which is adjacent to the slider when the device is fully closed 3.16 open-end slide fastener slide fastener having a special fitment at the bottom end of each stringer in place of the bottom stop, so as to permit the two stringers to be completely separated and re-assembled at will when the slider is in the fully open position Note 1 to entry: The special fitment normally consists of a pin permanently fixed to the bottom end of one stringer, which fits into a box permanently fixed to the bottom end of the other stringer. Note 2 to entry: See Figure 3c) and 4a). 3.17 closed-end slide fastener slide fastener which does not permit the complete separation of the two stringers Note 1 to entry: Normally the top end of the slide fastener separates as the slider is lowered, although there is one type whose top ends are permanently joined together by means of a bridge stop [see Figure 3a) and Figure 3b), 4b), 4c), 4d)]. 3.18 concealed slide fastener slide fastener with the tapes folded so that on closure neither the slider body nor the slide fastener are visible from the outside of the article Note 1 to entry: See Figure 1g). SIST EN 16732:2016
EN 16732:2015 (E) 10 3.19 two-way slide fastener slide fastener fitted with two sliders that operate with equal facility in either direction Note 1 to entry: This type is available in a variety of forms, as illustrated in Figure 4. 3.20 batch quantity of slide fasteners having a specific design, performance code and chain size 4 Requirements When subjected to the tests specified in Clause 5 (as applicable to the features of the slide fastener design to be tested), other than the slide fastener length measurements (see 5.2), samples of new slide fasteners shall conform to Table 1 and to Table 2 if applicable (children items). The overall performance for the slide fastener, as determined by the minimum test results, shall be that of the lowest performance grade achieved by any test specimen for any applicable test. Attention shall be given to the use of the sampling procedures given in Annex L with regard to the interpretation of potential outlier results. It is permissible to perform more than one test on the same slide fastener but care should be taken to ensure that damage sustained in testing does not compromise subsequent test results. A minimum of 3 specimens shall be tested in respect of each applicable test. Failure of any part of a slide fastener before the specified force or number of cycles is reached in any of these tests shall be deemed a failure of the sample. For the acceptance criteria for larger batches the sampling scheme in Annex L shall be used and the number of specimens for each test increased accordingly. Annex L gives information about an appropriate sampling procedure for bulk quantities of slide fasteners. Annex M gives information about end-use and performance codes. SIST EN 16732:2016
