Overview - ISO 15605:2000 (Adhesives - Sampling)
ISO 15605:2000 specifies standardized methods for sampling adhesives and related products to obtain uniform, representative samples of convenient size suitable for examination and preparation prior to testing. The standard covers single- and multi-component adhesives (components sampled separately when catalysts or hardeners are added) and excludes animal glues and sampling from a continuous adhesive stream (see ISO 8213 for that case).
Keywords: ISO 15605:2000, adhesive sampling, sampling adhesives standard, representative samples, laboratory sample.
Key topics and technical requirements
- Scope and definitions: clear terms such as batch, delivery, gross sample, laboratory sample, reference sample, storage sample and test sample are defined to ensure consistent sampling practice.
- Safety: guidance on hazards (flammability, explosion, solvent vapours, skin absorption), use of safety data sheets, grounding/earthing of large containers, avoiding static sparks, and recommended two-person procedures for large tanks.
- Product types: classification of adhesive forms (Types A–F: fluids, emulsions, dispersions, viscous mastics, powders, solids) to guide choice of sampling method.
- Sampling equipment: requirements for materials and design (non-contaminating, easy to clean), apparatus for mixing (broad-bladed stirrers) and sampling (weighted sampling cans, sampling tubes, scoops, spatulas), plus container types (metal, glass, polyethylene).
- Sampling methods: procedures for:
- manufacturing vessels (stirring and multi-level sampling for fluids),
- filling operations (sub-samples during transfer),
- viscous/powder products (tube or scoop sampling),
- packaged solids (sampling from rolls, sheets, blocks).
- Container filling and storage: fill sample containers generally 80–90% full (to allow expansion and mixing) except anaerobic adhesives (fill ≤ 50%); precautions for moisture-reactive, hygroscopic and light-sensitive adhesives (e.g., inert gas covers, lightproof containers).
- Labelling, sealing and reporting: requirements for identification, documentation of sampling report, and retention of reference/storage samples for dispute resolution.
- Cleaning: strict cleanliness and solvent rinsing of equipment to avoid contamination.
Applications - who uses ISO 15605:2000
- Adhesive manufacturers - quality control and batch release sampling.
- Testing laboratories - preparing representative laboratory and test samples for physical/chemical testing.
- Buyers, inspectors and regulatory bodies - incoming inspection, contract verification and dispute resolution using reference samples.
- R&D and formulation teams - consistent sampling during product development and stability studies.
Keywords: adhesive quality control, sampling procedures, representative adhesive sample.
