- Ribbed Smoked Sheets Grade 1 refers to Ribbed Smoked Sheets, produced from natural rubber latex as ribbed sheets, by coagulation with acids andsheeting,properly air dried and smoked, and visually graded.
- Ribbed smoked sheets1 (RSS1) are graded based on visual assessment of quality. The International Rubber Quality and PackingConference (IRQPC) have specified the grade descriptions, to establish acceptable grades for commercial usage.

Oxidized spots or streaks, weak, heated, under cured, over-smoked, opaque and burnt sheets are not permissible in this grade. The rubber must be dry, clean, strong, sound and evenly smoked, and free from blemishes, specks, resinous matter (rust), blisters, sand, dirty packing and any other foreign matter, except slight specks. Small pinhead bubbles, if scattered, will not be objected to.

Due to characteristic conditions and manufacturing method, RSS rubber is widely used in engineerings such as
manufacturing tire surface; RSS rubber is formed into sheets so the rubber is of high tensile force and less aging than granulated rubber. Therefore, this rubber is suitable for producing products which require high tear resistance, wear resistance and hardness.
