※ 引述《h800531 (大屁)》之铭言： : 各问球友大大 : 小弟当初贴短颗时的球皮本来就没海绵 : 也乱打了数年 : 如今升上大学 入了系队 : 有个很大的疑问 : 短颗没贴海绵 : 可以打正式比赛吗?? : 请各位回答吧!! : 感恩 : 红双喜PF4-871 2.04.03 A side of the blade used for striking the ball shall be covered with either ordinary pimpled rubber, with pimples outwards having a total thickness including adhesive of not more than 2.0mm, or sandwich rubber, with pimples inwards or outwards , having a total thickness including adhesive of not more than 4.0mm. 单胶 2.04.03.01 Ordinary pimpled rubber is a single layer of non-cellular rubber, natural or synthetic, with pimples evenly distributed over its surface at a density of not less than 10 per cm2 and not more than 30 per cm2. 三明治胶皮 2.04.03.02 Sandwich rubber is a single layer of cellular rubber covered with a single outer layer of ordinary pimpled rubber, the thickness of the pimpled rubber not being more than 2.0mm. 综合上面三条, 单胶: 无海绵, 颗粒必须朝外 三明治胶: 有海绵, 颗粒可以朝内或朝外 ITTF Racket Coverings Technical Leaflet T4 Authorisation is given to the top sheet alone. Red and black top sheets with the same supplier and brand name must have the same geometry, properties, wording and numbering. The surface colours must be uniform. Such red and black top sheets do not require separate authorisation fees. It is the player’s responsibility to limit the total thickness of his racket covering to no more than 4.0 mm, including top sheet, sponge and adhesive. It is also his responsibility to ensure that a red top sheet does not become too dark when affixed to the sponge, or a black covering too light. 简单的说, 现行规则胶皮认证不管海绵部分, 认证上胶而已 合格的颗粒朝外胶皮, 要不要贴海绵都属合格 --
