22、照 AMCA 标准进行测试”，但请注意这与“产品被获准使用 AMCA 国际的认证额定值印章”有本质区别。印有类似语句的印刷品仅仅表明该产品采用AMCA 公布的标准进行测试，但是其测试的数据不会被 AMCA 承认。2)另一个容易引致误会的方面是 AMCA 国际的认证额定值印章与 AMCA 会员证书之间的差异。有些生产厂商会将 AMCA 会员证书印在产品目录上，这容易让人误解为其产品已通过 AMCA 的测试及认证。红白的 AMCA 会员证书仅仅代表其为 AMCA 国际的会员，只有蓝黄色和绿黄色的认证额定值印章，才表明该产品是通过 AMCA 认证额定值程序(CRP)的测试，并被批准使用AMCA 国际
