Carbonyl nickel powder
1 Scope
This standard specifies the requirements, test methods, inspection rules, packaging,
marking, transportation, storage, quality certificate and purchase order (or contract)
content of carbonyl nickel powder.
This standard applies to nickel powder, which is produced by carbonyl method.

3 Requirements
3.1 Designations
Carbonyl nickel powder is divided into six designations, according to physical
properties: FNiT04, FNiT06, FNiT09, FNiT11, FNiT24, FNiT35. In which, FNiT
represents carbonyl nickel powder; the numbers represent different bulk density ranges.
3.2 Chemical composition
The chemical composition of carbonyl nickel powder shall meet the requirements in
Table 1.
out, according to the provisions of GB/T 3249.
4.5 Determination of bulk density of carbonyl nickel powder shall be carried out,
according to the provisions of GB/T 5061.
4.6 The sieving particle size of carbonyl nickel powder is sieved, by a sieve of
corresponding precision.
4.7 The appearance quality of carbonyl nickel powder is inspected visually.
5 Inspection rules
5.1 Inspection and acceptance
5.1.1 The product shall be inspected by the supplier, to ensure that the product complies
with the provisions of this standard or the purchase order (or contract); meanwhile fill
in the quality certificate.
5.1.2 The purchaser inspects the received products, according to the methods stipulated
in this standard or the purchase order (or contract). If the inspection results are
inconsistent with this standard or the purchase order (or contract), it shall be proposed
to the supplier, within 15 days after receiving the product, to be settled through
negotiation between the supplier and purchaser. If arbitration is needed, the arbitration
sampling shall be carried out, jointly by the supplier and purchaser.
5.2 Group-batching
Products shall be submitted for acceptance in batches. Each batch shall be composed of
products, which are produced by the same process and of the same designation; the
mass of each batch shall not exceed 10 tons.
5.3 Inspection items and sampling
The inspection items and sampling of each batch of products shall comply with the
provisions in Table 3.
5.4 Judgment of test results
5.4.1 If the chemical composition of carbonyl nickel powder is unqualified, this batch
of products is judged unqualified.
5.4.2 If the Fischer particle size and bulk density of carbonyl nickel powder are
unqualified, this batch of products is judged to be unqualified.
5.4.3 If the sieving particle size of carbonyl nickel powder is unqualified, the product
in this barrel is judged to be unqualified.
5.4.4 If the appearance quality of carbonyl nickel powder is unqualified, the product in
this barrel is judged to be unqualified.
6 Marking, packaging, transportation, storage, quality
certificate
6.1 Marking
The outer packaging of each barrel of product shall indicate:
a) The name and contact information of the supplier;
b) Product name and designation;
c) Batch number;
d) Net weight;
e) The date of packing;
f) The number of this standard.
6.2 Packaging
Carbonyl nickel powder is packaged in a thick plastic bag with sealed packaging; the
outer package is iron drum. The net weight of carbonyl nickel powder packaging is
divided into four specifications: 10 kg, 20 kg, 50 kg, 100 kg; it can also be packaged,
according to the requirements of the buyer.
6.3 Transport and storage
When transporting carbonyl nickel powder, it shall be handled with care and shall not
be bumped, rolled or inverted. Carbonyl nickel powder shall be stored in a dry, non-
corrosive atmosphere to prevent moisture.
6.4 Quality certificate
