ABSTRACT
This specification covers the properties and requirements for isopropyl alcohol. Specimens shall be suitably sampled and tested, and shall adhere accordingly to specified values of the following properties: apparent specific gravity; color (Pt-Co scale); distillation range; nonvolatile matter content; odor; water content; acidity (acetic acid); and water miscibility.
SCOPE
1.1 This specification covers isopropyl alcohol (99 % grade).
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D770-11(2019) is the internationally recognized standard specification for isopropyl alcohol (IPA) at the 99% grade. Developed by ASTM International, this standard details required properties, test methods, and sampling protocols to ensure the quality and consistency of isopropyl alcohol used across various industries. Adherence to this standard helps manufacturers, suppliers, and end-users align with global best practices, meet regulatory requirements, and ensure product performance for their intended applications.
Key Topics
- Material Requirements: Isopropyl alcohol must meet specific criteria regarding purity, often referred to as 99% grade.
- Physical and Chemical Properties:
- Apparent specific gravity at designated temperatures
- Color evaluation by standardized Pt-Co scale
- Defined distillation range for quality control
- Maximum allowable nonvolatile matter content
- Characteristic odor with no residuals
- Strict upper limits for water and acidity content
- Guaranteed water miscibility
- Test Methods: The standard references multiple ASTM test methods for verification, such as:
- Determination of specific gravity (Guide D268, Test Method D4052)
- Distillation range (Test Method D1078)
- Nonvolatile matter content (Test Method D1353)
- Odor testing (Test Method D1296)
- Water content (Test Methods D1364, D1476)
- Acidity (Test Method D1613)
- Water miscibility (Test Method D1722)
- Sampling and Packaging:
- Sampling must follow ASTM E300 guidelines
- Packaging size and markings are to be mutually agreed upon and in compliance with applicable regulations
- Safety, Health, and Environment:
- Users of isopropyl alcohol must establish safety procedures in compliance with local guidelines
- Safety Data Sheets (SDS) provided by suppliers must be reviewed for hazard information
Applications
Isopropyl alcohol that complies with ASTM D770 is widely used due to its strict quality benchmarks and traceability. Its typical applications include:
- Solvent and Cleaning Agent: Used for cleaning surfaces in manufacturing, laboratory, and healthcare settings
- Pharmaceutical and Cosmetic Manufacturing: Essential for sanitization, extraction, and formulation processes
- Paints and Coatings Industry: Utilized as a solvent for coatings, varnishes, and inks
- Automotive and Electronics: Employed for cleaning, degreasing, and residue removal from components and devices
By ensuring that isopropyl alcohol meets ASTM D770, organizations can prevent contamination, achieve reliable product performance, and comply with industry and regulatory requirements.
