Abstract

Overview

ISO 7387-1:1983 - Adhesives with solvents for assembly of PVC‑U pipe elements - Characterization - Part 1: Basic test methods defines the basic laboratory methods used to characterize solvent‑based adhesives for unplasticized polyvinyl chloride (PVC‑U) piping. Part 1 specifies three fundamental tests used to decide the uniformity and basic properties of these adhesives: viscosity (dynamic and Brookfield), conventional dry matter content, and ash content (where applicable).

Key topics and technical requirements

Viscosity (Section one)
- Two methods: dynamic viscosity according to shear rate (reference method) and Brookfield RV “viscosity” (manufacturing/inspection).
- Dynamic method: measures shear stress vs shear rate at controlled temperature to determine Newtonian or non‑Newtonian behaviour and produce z = f(γ) curves.
- Brookfield method: uses RV, RVF-100 or RVT viscometers with specified moving bodies and speeds; tests are normally run at 23 ± 1 °C in a thermostatted bath. Results reported as Brookfield RV viscosity with the speed/moving‑body pairing; stability and repeatability rules apply (consecutive readings tolerance).
- Practical measurement details: selection of speed and spindle to keep readings within instrument scale, expression of results to three significant figures, attention to thixotropy.
Conventional dry matter content (Section two)
- Procedure: deposit a defined test portion (≈0.5–1 g) on pre‑dried plates, allow solvent evaporation (10–15 min), then final drying at 110 °C for 60 min in a ventilated oven.
- Equipment: drying oven (thermal inertia), balance accurate to 0.1 mg, desiccator, syringe for sampling. Results expressed as percentage of residue relative to original mass.
Ash content (Section three)
- Included for adhesives that do not contain fillers unstable at test temperature. (ISO 7387-1 identifies ash content as a basic characterization parameter; specific procedural steps are given in the full standard.)

Applications and users

Quality control and incoming inspection for adhesive manufacturers, PVC‑U pipe and fittings producers, and fabricators.
R&D and formulation laboratories assessing batch-to-batch uniformity and rheological behaviour.
Third‑party testing and certification bodies establishing compliance with material specifications.
Procurement and specification writers who need objective test methods for supplier acceptance criteria.

Related standards

ISO 7387 (other parts): Part 2 (secondary test methods) and Part 3 (separation/characterization methods).
ISO 2555 is referenced as the basis for the Brookfield RV viscosity procedure.

Keywords: ISO 7387-1:1983, adhesives with solvents, PVC‑U pipe, viscosity testing, Brookfield viscosity, dynamic viscosity, dry matter content, ash content, solvent‑based adhesive characterization, test methods.
