Specification Overview:
This document outlines the specifications for GSF 1223, a foamed synthetic rubber (SR) material. The key specifications include flame rating, static coefficient of friction, specific gravity, compression set, thickness, and material hardness.

Flame Rating:
The material adheres to the UL 94 flame rating standard, which is crucial for determining the material's flammability characteristics.

Static Coefficient of Friction:
Measured according to ASTM D1894, the static coefficient of friction is specified as 0.5 ± 0.1, indicating the material's resistance to sliding.

Specific Gravity:
According to ASTM D792, the specific gravity of the rubber is 15 ± 10%, which provides insight into the material's density.

Compression Set:
The compression set is measured by compressing the material to 40% for 22 hours at 100°C, with a result of 0.8 ± 0.2mm, indicating the material's ability to return to its original thickness after compression.

Thickness:
The total thickness of the material is specified as 0.5 ~ 2.5 μ, measured by ASTM D374.

Material Hardness:
Measured using the Asker C scale according to JIS 6253, the hardness is determined by customer requirements.

Color:
The color of the material is determined visually and specified by the customer.
