Standard Specification for Liquid Chlorine
ABSTRACT
This specification covers industrial grade chlorine normally available as a liquid in pressurized metal containers. Liquid chlorine shall conform to the following requirements: gaseous impurities content, moisture content, and nonvolatile material content.
SCOPE
1.1 This specification covers industrial grade chlorine normally available as a liquid in pressurized metal containers.
1.2 The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, 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.
1.3 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, handling and safety precautions.
1.5 The following safety hazards caveat pertains only to the test methods listed in Sections 3 and 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.

Overview
ASTM E1120-21: Standard Specification for Liquid Chlorine provides requirements for industrial grade liquid chlorine, specifically for chlorine stored and transported in pressurized metal containers. This standard is widely used in industrial, commercial, and regulatory contexts where chlorine is required for various applications. ASTM E1120-21 details the essential chemical and purity specifications that liquid chlorine must meet to ensure safe and consistent quality for end users. The document also covers packaging, labeling, and applicable safety and regulatory guidelines.
Key Topics
Purity Requirements:
The standard outlines the maximum allowable levels of gaseous impurities, moisture, and nonvolatile material in liquid chlorine. These requirements are critical for maintaining product quality and safety during storage, handling, and application.- Maximum for gaseous impurities (by volume)
- Maximum for moisture (mass %)
- Maximum for nonvolatile material (mass %)
Testing and Sampling:
- Test methods for evaluating chlorine purity are referenced, such as ASTM E410 for moisture and residue, and ASTM E1746 for sampling and analysis of gaseous impurities.
- Sampling must be performed according to precise standards to verify compliance.
Packaging and Labeling:
- Packaging must align with U.S. Department of Transportation (DOT) regulations (Title 49 CFR) and, where applicable, Department of Defense requirements.
- For pesticide uses, labeling must comply with EPA regulations (Title 40 CFR).
- Occupational Safety and Health Administration (OSHA) regulations, including requirements for hazard communication and labeling, also apply.
Units and Conformance:
- SI (metric) units are the primary reference; imperial units are for guidance only.
- Rounding-off of values follows ASTM Practice E29 for consistency in data reporting.
Safety Considerations:
- Users must review the current Safety Data Sheets (SDS) and follow best practices in chemical handling, storage, and exposure response.
- The standard emphasizes the user's responsibility to ensure compliance with all relevant safety, health, and environmental regulations.
Applications
ASTM E1120-21 is essential in any industrial context where liquid chlorine is used or handled. Key application areas include:
- Water Treatment and Disinfection:
- Liquid chlorine is commonly used for municipal water purification and wastewater treatment facilities.
- Industrial Processing:
- Utilized in the production of chemicals, paper, plastics, solvents, and pharmaceuticals.
- Pesticide Formulation:
- When chlorine is used as a pesticide or in pest control, compliance with this specification ensures regulatory and safety standards.
- Shipping and Logistics:
- Relevant for manufacturers, suppliers, and logistics providers responsible for packaging, labeling, and transporting liquid chlorine.
Meeting ASTM E1120-21 ensures consistency, reliability, and safety for end users and regulators throughout the chlorine supply chain.
Related Standards
Several other standards provide support and additional detail for users of ASTM E1120-21:
- ASTM E29:
Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications - essential for rounding data values. - ASTM E410:
Test Method for Moisture and Residue in Liquid Chlorine. - ASTM E1746:
Test Method for Sampling and Analysis of Liquid Chlorine for Gaseous Impurities. - DOT Regulations (Title 49 CFR):
Covers transportation and container requirements for hazardous materials. - EPA Regulations (Title 40 CFR):
Relevant for pesticide labeling and environmental compliance. - OSHA Regulations (Title 29 CFR):
Addresses hazard communication and safety labeling for workplace chemicals.
Adhering to these related guidelines helps organizations achieve full regulatory compliance and maintain high safety and operational standards for liquid chlorine management.
