Foreword
GB/T 3408 "dam monitoring instrument strain gauge" is divided into four parts.
--- Part 1. Differential Resistance Strain Gages;
--- Part 2. Vibrating wire strain gauge;
--- Part 3. Resistive strain gauges;
--- Part 4. Inductance strain gauge.
This section GB/T 3408 Part 1 is the GB/T 3408-1994 "Resistive Strain Gauge" amendment. versus
GB/T 3408-1997 compared to the main changes are as follows.
--- Increased strain gauge performance parameters in the "reliability requirements" and other relevant provisions;
--- Modify the "range", "over range limit", "stability requirements", "anti-transport performance," and so on;
--- In the "Specifications and main parameters", added a new size and measurement specifications;
--- In the "inspection rules", on the "factory inspection" and "type test" provisions of the eligibility criteria were adjusted;
--- In the "test method", supplemented the "reference test atmospheric conditions", "normal experimental atmospheric conditions" and other environmental test conditions
content;
--- Modify and supplement the "logo", "Instruction Manual", "packaging", "transport" and "storage" and other related content.
This part of the GB/T 15406 "Geotechnical instrumentation basic parameters and general technical conditions" and other standards have a certain relationship between the convergence,
And in the technical content of mutual coordination.
Appendix A of this section is normative appendix.
