Amendment No. 1 to GB/T11606.1-1989 "General Rules for Environmental Test Methods for Analytical Instruments"
This amendment was approved and issued by the State Administration of Quality and Technical Supervision on July 19, 2000, and took effect on December 1, 2000. Published in the 9th issue of 2000 (China Standardization). 1. In Chapter 4, \50±0.1H\ is changed to \50±0.5H\. 2. In Chapter 5, "Constant temperature test" is changed to "Constant damp heat test". 3. The units in Table 1 should be placed below the project name. The test item "humidity" should be changed to "humid heat". The "humidity\" column in Table 1 is modified as follows:

1 Subject content and scope of application
GB11606.1--89
This standard specifies the environmental test grouping, reference working conditions, test items, selection of environmental groups, environmental tests and test procedures for analytical instruments (hereinafter referred to as instruments).
This standard is not applicable to marine analytical instruments. 2 Reference standards
GB2422 Environmental test procedures for electrical and electronic products Terminology GB2298 Mechanical vibration shock 3.1 Group I
The ambient temperature and humidity are controlled within the specified range, usually refers to a controlled environment with air conditioning equipment. Be careful when operating the instrument. This group is suitable for precision instruments.
3.2 Group II
Only the ambient temperature is controlled within the specified range, usually refers to an indoor environment with general insulation, heating and ventilation. The instrument is allowed to be subjected to general vibration during use. This group Applicable to laboratory instruments, 3.3 Group
Environment without ambient temperature and humidity control, usually refers to indoor environment without insulation, heating and ventilation. The use and transportation conditions of the instrument are poor. This group is suitable for industrial process instruments, 3.4 Group IV
Harder environment without ambient temperature and humidity control, usually refers to outdoor environment with or without shelter. The instrument may be subject to drastic environmental changes during use or transportation 4 Reference working conditions
Reference working conditions Reference values, errors and ranges are shown in Table 2. Without generating When there is disagreement, the test can be conducted under the conditions of 20±10℃, relative humidity less than 75%, power supply voltage of 220±22V, and power supply frequency of 50±0.1Hz.
5 Test items
There are 16 environmental tests, namely power supply frequency and voltage test, low temperature test, high temperature test, temperature change test, constant mixing test, alternating damp heat test, vibration test, magnetic field test, air pressure test, sand and dust test, long test, salt spray test, low temperature storage test, high temperature storage test, drop test and collision test. Approved by the Ministry of Machinery and Electronics Industry of the People's Republic of China on March 25, 1989 and implemented on March 1, 1990
6 Selection of environmental grouping
GB11606.1-89
6.1 The product standard shall select the environmental grouping according to Chapter 3. If a certain (generally only one) impact quantity is not completely consistent with the environmental conditions of the specified group, the product standard shall be specified separately.
6.2 When it is not feasible to test a large product as a whole, the relevant standards shall specify which key parts or components shall be tested. 6.3 The test items listed in Table 1 are the items that the instrument must perform. 7 Environmental Tests
Each test usually includes the following items:
Pretreatment (if necessary);
b. Initial inspection (if necessary):
c. Test;
d. Intermediate inspection (if necessary);
e. Recovery (if necessary);
f. Final inspection.
Test Sequence
When two or more test items are performed on the same instrument in sequence, the sequence is generally not specified. If the test sequence has an impact, it shall be specified by the relevant standards.
