Foreword
This Document was drafted as per the rules specified in GB/T 1.1-2020 Directives for
Standardization – Part 1.Rules for the Structure and Drafting of Standardizing Documents.
This Document replaced GB/T 3683-2011 Rubber Hoses and Hose Assemblies - Wire-Braid-
Reinforced Hydraulic Types for Oil-Based or Water-Based Fluids – Specification. Compared
with GB/T 3683-2011, the major technical changes of this Document are as follows besides t
he structural adjustments and editorial modifications.
--- Change "R1ATS" to "R1AT"; and change "R2ATS" to "R2AT" (see Clause 4, 6.1, Clause
7 of this Edition; Clause 4, 6.2, Clause 7 of the 2011 Edition);
--- Change the scope; increase the upper limit temperature of water-based hydraulic fluid
from +60 ℃ to +70 ℃; and add the relevant requirements for the fluid medium to be
water (see Clause 1 of this Edition; Clause 1 of the 2011 Edition);
--- Add hoses with a nominal inner diameter of 76 and relevant requirements (see 6.1 of this
Edition);
--- Change the maximum working pressure, verification pressure and minimum burst
pressure in Table 4 to the most common standard pressure (see 7.2 of this Edition; 7.2 of
the 2011 Edition);
--- Change the measurement method of the minimum bending radius (see 7.3 of this Edition;
7.3 of the 2011 Edition);
--- Change the fluid temperature of the water-based fluid pulse test from +60 ℃ to +70 ℃;
incorporate the "optional pulse test" into it (see 7.4.2 of this Edition; 7.4.3 of the 2011
Edition);
--- Add the specimen model "Type 8" for the measurement of bonding strength between the
outer covering layer and the reinforcement layer (see 7.7 of this Edition);
--- Add the requirements for wear resistance (see 7.9 of this Edition);
--- Change the immersion temperature requirement for water resistance from +60℃ to +70℃
(see 7.10.3 of this Edition; 7.10 of the 2011 Edition);
--- Add the frequency of inspections in Clause 8 (see Clause 8 of this Edition);
--- Change some marking requirements (see Clause 9 of this Edition; Clause 8 of the 2011
edition).
This Document equivalently adopts ISO 1436.2020 Rubber Hoses and Hose Assemblies – Wire-
Braid-Reinforced Hydraulic Types for Oil-Based or Water-Based Fluids – Specification.
This Document made the minimum editorial modifications as follows.
--- ISO 1436.2020 does not provide clear values for the outer diameter, minimum outer
cladding thickness, and maximum outer cladding thickness of the 2SN and R2AT types
with a nominal inner diameter of 76.This Document gives the outer diameter reference
value to be 96.6mm, the minimum outer cladding thickness reference value to be 1.3mm,
the maximum outer cladding thickness reference value to be 2.5mm (see 6.1 of this
Edition);
--- Delete the “bar” unit expression in the text and only retain the “MPa” unit expression.
