Scope
GB/T 32065.5-2015 is the English-translated version of 海洋仪器环境试验方法 第5部分：高温贮存试验.
GB/T 32065.5-2015 is the part of GB/T 32065 that specifies the high temperature (dry heat) storage test for marine instruments, setting out its test requirements, test procedure and the related information.
Clause 1 states that the part applies to assessing or determining how well marine instruments withstand a high-temperature environment under storage conditions.
Clause 3 fixes the test requirements: standard atmospheric conditions, specimen mounting, test temperature stabilisation and the handling of test interruptions follow 4.2, 6.1, 6.2 and clause 7 of GB/T 32065.1-2015, and the test equipment follows clause 5 of the same part.
The same clause requires the specimen to sit as near the centre of the chamber as possible, with no surface of it closer than 15 cm to the chamber wall, chamber air speed no greater than 1.7 m/s, no direct radiation from heating or cooling elements, and chamber water vapour content no higher than 20 g/m3, equivalent to 35 °C at 50% relative humidity.
Unless specified otherwise the test temperature is chosen as (55 ± 2) °C or (70 ± 2) °C, with a note restricting 70 °C to extreme storage conditions near the equator, such as North Africa, the Middle East, Pakistan and India, the south-western United States and northern Mexico, and the default test duration is 8 h.
Clause 4 describes the test process, beginning with pretreatment of the specimen under standard atmospheric conditions until its temperature stabilises.
The foreword lists GB/T 32065 as a seventeen-part series of environmental test methods for marine instruments, running from general provisions through low temperature and low-temperature storage, high temperature and high-temperature storage, damp heat, temperature change, mould growth, salt spray, impact, bump, tilt and swing, vibration, hydrostatic pressure and seawater corrosion to a combined temperature-humidity-vibration test, and this part cites GB/T 32065.1-2015 as a normative reference.
It was proposed by the State Oceanic Administration, is administered by the National Technical Committee for Oceanography Standardization (SAC/TC283) and was drafted by the National Marine Standards and Metrology Center. It was issued on 9 October 2015 and has applied since 1 January 2016.
