4.1 Overview
Environmental testing is to expose products to natural or artificial environments, so as to evaluate their performance under the storage, transportation and use conditions that they may encounter in practice.
4.1.1 Alarm system standards should make provisions for which test items to be carried out, which test methods to use, the severity and the test sequence (if relevant) based on the environmental conditions that the product may encounter, after analyzing them from technical and economic aspects. Note: The relevant standards refer to the general standards and product standards for security alarm systems. They describe the complete set of requirements that systems, equipment or components should meet, and specify the corresponding test methods, detection requirements, and qualified criteria. 4.1.2 The relevant standards for alarm systems shall specify the permissible performance limits of the test samples during the test. 4.1.3 When it is impossible to test the entire machine for large products, the relevant standards shall specify which key extensions or components are to be tested. 4.1.4 Samples that have undergone environmental tests are generally not considered "new" unless otherwise agreed upon by the supply and demand parties or otherwise specified in the relevant standards. 4.2 Classification of environmental tests
4.2.1 Environmental tests are divided into two categories
Class A test: Working test
Class B test: Accelerated test
4. 2.2 Purpose of Class A test
a. To evaluate the ability of the test sample to work normally under the influence of the use environment. b. To evaluate the ability of the test sample to resist false alarms and (or) leak alarms under the influence of certain special environmental conditions. When conducting a Class B test, the test sample is exposed to environmental conditions whose effects are equivalent to those of the use environment. 4.2.3 Purpose of Class B test
To evaluate the ability of the test sample to withstand such conditions by increasing the intensity of a factor or increasing the proportion of time of action, and to obtain data on its long-term stability.
