Introduction

Core changes in the standard revision

Technical dimensions	2008 version	2020 version	Range of changes
Number of models	10 types	6 types	Reduced by 40%
Component accuracy	±5%	±2%	Accuracy improved by 150%
Sulfur content limit	10μg/mL	5mg/kg	50 times stricter

Analysis of key indicators

The new standard increases the total purity of pentane from ≥98% to ≥99%, and reduces the limit of C6 heavy components from ≤1% to ≤0.5%. New testing requirements for cyclopentane and 2,2-dimethylpropane are added, and the evaporation residue standard is 10 times stricter (≤1mg/100mL).

Testing method upgrade

Component analysis: SY/T0542→SH/T0714/SH/T1790
Sulfur content detection: New UV fluorescence method (SH/T0689)
Moisture determination: Introducing the coulometric method (SH/T0246)

Safety implementation suggestions

After a polystyrene production enterprise upgraded to F5 type foaming agent, it:
1. Added nitrogen protection system to the storage tank
2. Installed UV fluorescence sulfur analyzer
3. Used SH/T1790 as the arbitration method
The product qualification rate increased by 12%

Technology Evolution Background

As the EU REACH regulation tightens restrictions on VOCs in blowing agents, this revision also improves:
- Bromine index control requirements (≤100mg/100g)
- Cancel backward indicators such as copper corrosion
- Clarify that the filling coefficient of mobile containers is ≤0.85
