Adhesive - Sampling
WARNING — Persons using this Standard should be familiar with normal
laboratory practice. This Standard does not purport to address all the
safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to
ensure compliance with any international or national regulatory
conditions.
1 Scope
This Standard specifies methods for sampling adhesives and related products, in order to obtain uniform samples of convenient size which are adequately representative of the product being sampled. The sample or samples so
obtained are suitable for examination and preparation prior to testing. The methods are applicable to products which require the addition and mixing in of catalysts or hardeners prior to their application, by sampling each component separately. The methods are not applicable, however, to sampling from a stream of adhesive (in this case the samples shall be taken in
accordance with ISO 8213). This Standard does not apply to sampling of animal glues.
2 Normative references

For the dated references, their subsequent amendments (excluding corrections) or revisions do not apply to this Standard. However, the parties who enter into agreement based on this Standard are encouraged to investigate whether the latest editions of these documents are applicable. For undated reference documents, the latest
editions apply to this Standard.
