GB/T 7160-2017Carbonyl nickel powder (English PDF)

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.

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.

5.3 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.

6.1 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. […]
