—对设备的可靠性要求，采取了更为灵活的表达方式。将预热时间也作为可靠性的要求;

—对泵的维护间隔，由3个月修订为6个月;

—对标准试验条件作了修订，增加流量条件，减少了预热时间;

—对相对固有误差的线性要求，由20%修订为10%;

—对指示稳定性试验要求的持续时间，由500h修订为100h;

—对报警阂值稳定性试验要求的时间由500h变为100h;

—室内环境温度由100C-50℃修订为100C-350C;

—环境温度试验的保持时间由4h修订为24h;

—相对湿度试验的温度由30℃修订为35'C;

—电源电压增加了其他系列(原标准只一种220VA.C.);

—编辑格式等同IEC60761-1:20020
