ASTM D1051 defines the specifications for rubber insulating sleeves used to protect arms from electrical shock. It outlines classification by voltage rating, required physical and dielectric tests, and proper labeling and packaging, ensuring sleeves are safe, reliable, and effective in electrical work.
Sleeves must pass various tests, including dielectric strength, tensile strength, elongation, and ozone resistance, as specified within the standard. It also includes provisions for labeling, marking, and packaging to ensure proper identification and safe application. ASTM D1051 is essential for the production of reliable and safe insulating sleeves, complementing the protection offered by insulating gloves.
