According to the original national economic! Industry to the national light 1399.2 meaning, "in the release of economic professional standards, clean up the entire part of the national standard for the light industry standard is relatively accurate, the B939.3-19 reduction test method has been transformed into QB/1385321; the original GB8389.4.15878 calculation of the inspection rules, signs, packaging, transportation and pregnancy 2 has been transformed into: QB/3857.19: the original 39.5-1576 safety account has been branded as Q/3857.419, standard -BT8389.?19X will be general technical cases and B/3857.8857.4-1 02 is expected to be set. This standard is more difficult than the above standard:
has trained the necessary technical personnel, and has made extensive adjustments to the content of the document, and has completed the product test head (Sichuan etc.) This standard is the same as the standard 1N2?: 37 steel and the common technical conditions are more related, the standard is a common record,
