1 Scope and field of application
This part of ISO 6741 specifies methods for obtaining laboratory samples for mass determination by one of the methods given in ISO 6741-1. The method appropriate for particular fibres is indicated in ISO 6741-4
The procedures comprise :
| Nature of consignment | Procedure described | |
|---|---|---|
| Bulk staple in bales | Hand sampling (two methods) Core sampling |
|
| Tow and strands in bales and cases | Hand sampling | |
| Unsupported wound or coiled packages of raw silk, tow sliver, top or yarn in containers | Hand sampling | |
| Yarn wound on supports | Cutting method Winding (four methods) |

When a replicate sample is required for other tests or as a precaution against misadventure, the mass taken during sampling shall be doubled and the sample shall then immediately be halved to provide the two samples.
