ABSTRACT This specification details the minimum property, design and construction requirements for flexible removable and reusable blanket insulation for hot service of above ambient temperatures. Insulation must be one of the following flexible fibrous materials acceptable for the maximum temperature of service: high temperature fiber blanket of any type or grade; needled glass fiber mechanically bonded felt; and mineral fiber blanket of the type suitable for the application. The material for the outer jacket liner and straps, where used, shall either be plain woven glass fiber fabric or that which has been treated with a water resistant compound such as silicone or fluorocarbon, and conforms with the following requirements: minimum weight; breaking strength; tear strength; burst strength; abrasion resistance; color; temperature resistance; and flame resistance. SCOPE 1.1 This specification addresses the minimum requirements for materials and fabrication of flexible removable and reusable blanket insulation for hot service, from above ambient temperatures to 1000°F (538°C). 1.2 This specification separately addresses industrial applications, outdoor commercial applications, and indoor commercial applications. Blanket insulation for industrial applications and outdoor commercial applications must be weather resistant and resistant to liquid chemicals. Blanket insulation for indoor commercial applications is limited to 500°F (260°C) maximum use temperature, is not required to be either weather resistant or resistant to chemicals, and is typically used for HVAC, plumbing, and other light grade indoor piping systems that distribute steam or water, or both. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 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.
Abstract
Overview
ASTM C1695-22: Standard Specification for Fabrication of Flexible Removable and Reusable Blanket Insulation for Hot Service is a critical international standard developed by ASTM for the thermal insulation industry. This specification sets the minimum requirements for the materials, design, and construction of flexible, removable, and reusable insulation blankets used in hot service applications above ambient temperatures, up to 1000°F (538°C). The standard covers a range of fibrous insulation materials including high-temperature fiber blankets, needled glass fiber felts, mineral fiber blankets, microporous thermal insulation, and flexible aerogel insulation, all tailored for specific operational requirements.
Key Topics
- Material Requirements: The standard outlines acceptable insulation materials, including high-temperature fiber blankets (per ASTM C892), needled glass fiber felt (ASTM C1086), mineral fiber blankets (ASTM C553), microporous insulation (ASTM C1676), and aerogel insulation (ASTM C1728). For outer jackets, liners, and straps, woven glass fiber fabric treated with water-resistant compounds such as silicone or PTFE is specified.
- Performance Criteria: Materials must meet specified minimums for weight, breaking strength, tear strength, burst strength, abrasion resistance, temperature resistance, and flame resistance.
- Fabrication and Design: Requirements include pre-measurement for a tight fit, construction details for seams, parting faces for drainage, overlap with adjacent insulation, and geometric design to avoid force-folding. There are also detailed stipulations for tie-down straps, drawstrings, and identification tags.
- Application-Specific Criteria: The standard distinguishes between industrial, outdoor commercial, and indoor commercial applications:
- Industrial and outdoor applications require weather and chemical resistance.
- Indoor commercial insulation (e.g., HVAC or plumbing) is rated for temperatures up to 500°F (260°C) and is typically not required to provide weather or chemical resistance.
- Quality Assurance: Detailed inspection, rejection, and tagging protocols ensure correct identification and tracking of insulation products.
Applications
ASTM C1695-22 is essential for industries where energy conservation, safety, and maintenance flexibility are critical. Examples include:
- Industrial Facilities: Insulation for valves, flanges, piping, and equipment operating at high temperatures, often exposed to outdoor conditions, chemicals, or physical abuse.
- Power Plants and Refineries: Removable and reusable blankets allow for easy access for inspection and maintenance while providing thermal efficiency and personnel protection.
- HVAC and Commercial Plumbing Systems: Indoor removable insulation for steam, hot water, and process piping ensures easy maintenance while maintaining energy efficiency.
- OEM Equipment: Manufacturers can design equipment with tailored, removable insulation solutions that meet demanding operational or environmental requirements.
Removable and reusable insulation blankets built to ASTM C1695-22 offer significant benefits, such as:
- Simplified maintenance and inspection with minimal downtime
- Enhanced worker safety through controlled surface temperatures
- Improved process efficiency via consistent thermal insulation
- Reduced waste and cost over the lifecycle of insulated assets
