BS EN ISO 10320:1999 pdf free.Geotextiles and geotextile-related products — Identification on site.
BS EN ISO 10320 specifies the information accompanying geotextiles and geotextile-related products to enable the user on site to identify the goods as being identical to the goods ordered. The positive identification, e.g. of unwrapped or rolled-out geotextiles, is an important aim of this standard. The information specified does not replace that on a technical data sheet, and cannot be used to verify the compliance of the product with the technical requirements.
In addition, there shall be a means of positively identifying the product at the time of its installation, even if it is no longer in the original packaging.
In the case of geotextiles (GTX), the product name and type shall be marked on the product, e.g. by printing along the edge. The marking shall be easily legible and sufficiently durable to permit identification at the time of installation, and shall be repeated at regular intervals of at most 5 m.
In the case of geotextile-related products (GTP), the marking may be as for GTX, or it may for example take the form of tags affixed to the roll edge at intervals of at most 5 m. Examples of other possible systems for GTP are the inclusion of a printed ribbon wound up into the roll, or colour-marking of the edge of the roll. In this latter case, details of the colour codes used shall be included on the unit label. Where the product is further processed, e.g. cut, so as to render product marking impractical, each unit shall nevertheless have a unique identification.
