Full title and description

ASTM D1045-19 — Standard Test Methods for Sampling and Testing Plasticizers Used in Plastics. This document provides standardized procedures for sampling liquid plasticizers and for routine laboratory tests (acid number, ester content, specific gravity, color, refractive index, and water content) used to establish and confirm quality control for plasticizer materials.

Abstract

These test methods define how to collect representative samples from storage and transport (including tank cars and other large vessels) and how to perform a set of routine analytical determinations on liquid plasticizers used in compounding plastics. The standard emphasizes SI units, references established ASTM test methods for individual determinations, and includes safety notes for reagents and measurement equipment.

Scope

This standard covers sampling and testing of liquid plasticizers used in the compounding of plastics. Specific determinations included are acid number, ester content (where applicable), specific gravity (relative density), color (using referenced colorimetric scales), refractive index, and water content (e.g., Karl Fischer). The standard specifies representative sampling procedures (including composite sampling from large vessels) and directs users to referenced ASTM methods for individual measurements. SI units are the standard of record.

Key topics and requirements

• Representative sampling procedures for bulk containers and shipments (composite sampling; minimum composite volumes referenced for large vessels).
• Routine test determinations: acid number, ester content, specific gravity (relative density), color (Platinum‑Cobalt / Gardner / tristimulus methods), refractive index, and water content (Karl Fischer titration referenced).
• Use of SI units as the standard; parenthetical customary units may be shown for information.
• References to and reliance on established ASTM companion methods (e.g., D1209, D1218, D1544, D4052, D3465, E203, D1193) for specific measurements and procedures.
• Safety considerations for hazardous reagents and for equipment such as mercury thermometers (specific hazards discussed in the standard’s hazard section).

Typical use and users

Primary users are quality control and analytical laboratories at plasticizer manufacturers, plastic compounders and processors, raw material procurement teams, and third‑party testing laboratories. The methods are intended for routine acceptance testing, in‑process quality control, and verification of incoming shipments of liquid plasticizers.
