This document shall be given the status of a national standard, either by publication of an identical text

or by endorsement, at the latest by month year of DOP, and conflicting national standards shall be

withdrawn at the latest by month year of DOW.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent

rights.

According to the CEN-CENELEC Internal Regulations, the national standards organizations of the

1 – Scope:
2 09/2020
This document specifies the electrolytic cadmium plating of
parts and fasteners (addition of "and fasteners").
2 – Normative references:
EN 9100 is not a normative reference anymore.
EN 9100 has been added in bibliography.
The reason is that according to CEN/CENELEC Internal
regulations Part 3 (February 2017) (see 33 – Aspects of
conformity assessment) "no document containing
requirements for products, processes, services, persons,
systems and bodies shall make conformity dependent on a
quality management systems standard, i.e. it shall not, for
example, make normative reference to ISO 9001".
3.1 – batch:
Addition of "Note 1 to entry: For mechanical parts, hydrogen
embrittlement relieved at the same time".
4 – Purpose of process:
Introduction of three types:
- Type 1: as plated,
- Type 2: with hexavalent chromium based post-treatment,
---------------------- Page: 5 ----------------------
SIST EN 2133:2021
EN 2133:2020 (E)
- Type 3: without hexavalent chromium.
8 – Information for the processor:
"Requirements for finishing operations other than
chromating, e.g. phosphating" has been replaced by
"Requirements for finishing operations other than Type 2 or
Type 3 post-treatment, e.g. phosphating".
Table 1 – Stress relief heat treatment of steel parts:
Removal of the tolerance of ± 10 °C.
Addition of the note b.
For 1 100 MPa < UTS ≤ 1 450 MPa: the duration is 4 h min.
(instead of 1 h min.) and stress relief heat treatment is now
from 175 °C to 215 °C (instead of 190 °C to 230 °C).
For carburized parts, stress relief heat treatment is now
from 130 °C to 160 °C (instead of 130 °C to 150 °C).
10 – Process schedule:
Addition of a process flow chart (see Annex A).
10.2 – Masking:
Editorial change: masking (instead of covering).
10.4 – Nickel strike:
Nickel strike is mandatory on corrosion resisting steels and
is necessary on other type of steels.
10.5 – Cadmium plating:
If brighteners are used, absence of hydrogen embrittlement
shall be verified in accordance with ASTM F519.
11.1 – Hydrogen-embrittlement-relief heat treatment:
Editorial change: hydrogen-embrittlement-relief (instead of
de-embrittlement).
Table 2 – Hydrogen-embrittlement-relief of steel parts:
Removal of the tolerance of ± 10 °C.
Addition of the note b.
For 1 100 MPa < UTS ≤ 1 450 MPa: the hydrogen-
embrittlement–relief heat treatment is now from 175 °C to
215 °C (instead of 190 °C to 230 °C).
For carburized or nitrited parts, the hydrogen-
embrittlement –relief heat treatment is now from 130 °C to
160 °C (instead of 130 °C to 150 °C).
11.2 – Post-treatment:
The term "Post-treatment" is used instead of "chromating".
Introduction of Types 1, 2 and 3 within this subclause.

New requirements depending on the type.
13.4 – Hydrogen embrittlement of steels:
Requirements are now detailed for parts and for fasteners.

Requirements are now detailed for burnishing test and for
grid test.

Full revision of the requirements of this subclause.
14.1.5 – Corrosion resistance:
Requirements are now detailed for parts and for fasteners.
14.2.3 – Coating thickness:
Addition of requirements regarding the measurement of the
thickness in the hard-to-reach areas.
