9701-1988是比较老的（1988年）使用传统显微硬度计的测试方法从侧面进行薄膜硬度的测试，目的是从侧面避开基材对薄膜的影响。该方法有一定的局限性，标准中明确规定该方法要求覆盖层必须具有足够的厚度。当膜很薄时对于传统显微硬度计来说，会有以下影响：<br /> - 精确定位测量点（压入点与观察点的偏差），避免压入点压出薄膜范围，或太靠近边缘影响区扩展到基材；<br /> - 控制合适的载荷，载荷太大会有膜剥落的影响，以及较大压痕的侧面影响区也会扩展到侧面基材，导致测量结果偏差；<br /> - 光学测量压痕对角线尺寸，对于小载荷小压痕测试的情况下，光学方法测量而导致的误差；<br /> <br /> 而纳米压痕是目前最直接最精确测量涂镀层或薄膜硬度的测试方法，国际标准ISO14577和国标GBT21838是目前专门针对仪器化压痕法测量涂镀层和膜硬度的标准，这种测试手段也突破了显微硬度计的测量限制，无需光学测量压痕尺寸，不因压痕过小导致测量误差，且能实时掌握压入深度等参数，对于不同膜厚控制不同的载荷和压入深度以保证避免基材的影响。传统的显微硬度计因无法做到这些所以只能采用侧面测试的方法。 对于菲希尔的纳米压痕仪，无论是侧面还是正面都可以满足测试要求，而对于大部分致密覆盖层而言，纳米压痕仪直接从正面测量即可。菲希尔的设备是完全按照ISO14577标准设计的，且菲希尔本身也是制定该标准的成员之一， 对于涂镀层或薄膜的硬度测试的标准要求更为熟知。菲希尔设备最低载荷能达到5μN（0.005mN）,对于1μm甚至更薄的薄层也能测试其硬度等其它力学参量。<br />
