网球，地板铺设产品，网球场地国际网联ITF认证中正检测为您服务

国际网联认证（ITF）是网球比赛管理机构，其职责义务包括确定网球运动相关规则。多年来，网球相关科学研究水平已被限制于其他体育活动。自1997 年ITF技术中心成立以来，在网球设施设备以及网球比赛者所受到这一领域技术发展的影响的推动下，网球科技和技术已经逐步提升。
The International Tennis Federation(ITF) is the governing body of the game of tennis and its duties and responsibilities include determination of the Rules of Tennis.For many years the level of global scientific research into tennis-related topics has been limited in relation to other sports of comparative size. Since the establishment of the ITF Technical Centre in 1997, the profile of tennis science and technology has been raised through the encouragement of research in the areas of tennis equipment, tennis facilities and the way in which the tennis player is affected by developments in these areas.
网球认证
技术中心关键的职责是网球的认证测试-任何锦标赛中使用的网球通过ITF检验认证，测试在技术中心实验室内进行。
A key function of the Technical Centre is tennis ball approval – any ball used in tournament play must be approved by the ITF, based on the tests conducted in this laboratory.
每个测试项目都有验证失败的可能，所有项目中易失败的是回弹和变形测试，不易失败的是尺寸和质量测试。任何一个项目验证失败，则认证无法通过。制造商需重新申请并另外提供样品，任何样品均采用相同的测试方式进行测试。
Failures occur in all tests, but the most common are the rebound and deformation tests. Least common are the size and mass tests. If a brand fails, then approval cannot be granted. The manufacturer must re-apply by sending another sample, which is then tested in the same way.
场地速度评级
ITF比赛场地速度评级的发展，主要目的在于帮助网球场地产品购买者区分不同的产品类型，并表面速度符合其要求。ITF对场地速度进行了五中分级：
种类1 慢速
种类2 中等慢速
种类3 中速
种类4 中等快速
种类5 快速
The ITF Court Pace Classification Programme has been developed to assist purchasers of tennis surface products to determine the type and speed of surface most suited to their requirements. The ITF classifies surfaces into five categories according to court pace:
Category 1 (slow)
Category 2 (medium-slow)
Category 3 (medium)
Category 4 (medium-fast)
Category 5 (fast)
ITF场地速度等级（CPR）主要对场地和网球表面的相互作用进行测试。这个概念包括摩擦力和恢复特性。擦力主要确认地面与网球表面接触时，地面对网球水平方向运行速度的影响性能；而恢复特性主要确认两次连续弹跳的间隔时间。
The ITF Court Pace Rating (CPR) measures the effect of ball-surface interaction. This concept includes: friction, which primarily determines the reduction in the horizontal component of post-impact ball velocity; and vertical restitution, which determines the time between successive bounces.
球拍性能测试
网球拍性能测试仪器（被称为“MYO”-希腊语意为“力量”）是一个用于测试球拍大受力的常规仪器。每个球拍将在三种不同的球拍速度和球拍表面六个不用的受力点进行测试，以测定球拍前端佳的受力点。
The racket performance machine (known as “MYO” – the Greek word for muscle) is a custom built machine designed to measure the maximum power a racket can generate. Each racket is tested using three different racket speeds and six different impact locations on the face of the racket to identify the optimal power point on the racket head.
ITF认证适用产品类型：
1. Tennis balls 网球
2. Tennis courts Surface网球场
3.地板产品
