GB/T 13376-2008Plastic scintillators (English PDF)

Foreword

This standard replaces GB/T 13376-1992 "plastic scintillator." This standard compared with GB/T 13376-1992 main changes are as follows:

--- Increasing the term "beta and gamma efficiency ratio" (see 3.5);

--- Table table title will be increased;

--- Table 3 reduced the number of defects allowed to exist and size (see 5.2);

--- Original table is split into 5 tables 5 and 6, in order to articulate common plastic scintillator core performance indicators and high beta/gamma-type plastic scintillator The core performance indicators (see 5.4);

--- Increasing the measurement probe beta/gamma-type plastic scintillator (see 6.6);

--- Detailed drawing of FIG. 3, the single-photon measurement of scintillation decay time measuring devices more intuitive (see 6.8.2). The standard proposed by China National Nuclear Corporation. This standard by the National Standardization Technical Committee on nuclear instrumentation. This standard was drafted. nuclear (Beijing) Nuclear Instrument Factory. The main drafters of this standard. Qu Yuhui. This standard replaces the previous standard release case. GB/T 13376-1992. Plastic scintillator

1 Scope

GB/T 13376-2008 is the Chinese national standard on plastic scintillators, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 2 July 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2009. Classification: ICS 27.120, CCS F88. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the classification of plastic scintillator, technical requirements, test methods, inspection rules, packaging and storage. This standard applies to all kinds of plastic scintillator products, these products quality inspection and quality assessment basis.
