This standard is a revision of QR 3812.21990 for the measurement of physical properties of pressure test pieces for gas conditioning. This standard amends and adopts S0241y:2002 for the measurement of physical properties of pressure test pieces for gas conditioning (Lrhcr-Physicaandmcchaniua[lessSampleparationandconditioning]), and is the standard of the International Federation of Automotive Engineers and Chemists TTCS PP.
QB/T3812.2—1999 and other standards adopted 152419:J972: [S02419 has been revised, and IS02419:2002 has replaced 502419:1972.
This standard is based on TS02419:2002 and was re-written. This standard was based on the actual situation in my country. When adopting 1S258:2002, it was revised with a technical policy. The original standard did not have a "normative text" and stipulated in Article 5 that "sampling should be carried out according to TS0241R". The small standard has a "standard steam guide piece support chapter". Its number and order are in accordance with the Chinese legal readability, and the "technical and In the "Definition", 1 "am1opheT", the relevant content is merged with 2.2, without affecting the use of terms and definitions, and is consistent with the international terminology standards; in order to facilitate the general use of the attached "Notes", this standard also makes the following editorial modifications: except for the following ISO standard prefix:
The "International Standard" is changed to "This Standard" in the standard. Compared with Q/3512.21099, the following changes are added: 2 "Normative references", 3 "Terms and definitions", 4 "Standard air", 5 "Model", 6 "Selection and preparation of samples", 8 "Test", 9 "Test report" content; the "word section" is deleted.

The following terms and definitions apply to this document: 3.1
Standard air
The air is determined by the specified temperature and humidity. It is stored in the specified environment within the specified range. The air quality is guaranteed. 3.2
The sample is placed in a slow-flow pool at the specified temperature and humidity. The sample can be brought to the specified temperature by the slow-flow pool. This can be done by the specified temperature.
4 Standard air
Standard air and allowable deviations are shown in Table 1. Standard air and allowable deviations

: Only the health conditions of the M are reported separately, generally speaking, the air temperature is 2D), the standard air temperature is 2D), the standard air temperature is 2D), the standard air temperature is 2D), the standard air temperature is 2D), the standard air temperature is 2D), the standard air temperature is 2D), the standard air temperature is 2D, ... 2 Preparation of the sample: Use a knife to cut the sample from the hot surface (or the estimated surface). If there is no grain surface (grain mountain), cut the sample from the use. If the sample is selected, it should be conditioned before the initial use. 7 General table: Put the sample into the standard air, and the surface should be slightly touched by the stagnant air. The 48h conditioning should be carried out before the test.
8 Test
The test should be carried out in the standard air selected by the test manufacturer, and there will be other provisions in the test method. 9 Test report
The test report shall include the following contents:
Specimen name, serial number, type;
Detailed information on the selected product culture, sampling and Q/T2706-2005 or one or more standard gases (such as 2065% or 2350%)
