systems on agricultural tractors and selfpropelled machines.
NOTES:
1 The term ‘vehicle’ in the standard refers to agricultural
tractors and self- propelled machines and is used for editorial
clarity and conciseness.
2. Minimum recommended perf ormance levels for acceptable
comfort purposes are set out in Appendix B.
3. This standard covers performances for new air-condit ioning
systems only.
4. This standard does not cover assessment of the abil ity of the
fi lt ration system to deal with hazardous dust or chemicals.
