JC/T 897-2014Antiseptic function of antibacterial ceramic (English PDF)

Foreword

This Standard is drafted according to the rules given in the GB/T 1.1-2009.

This Standard replaces the JC/T 897-2002 Antiseptic function of antibacterial

ceramic. Compared with the JC/T 897-2002, besides the editorial changes, the

major technical changes are as follows.

— ADD the "Normative references" (SEE Chapter 2 of this edition);

— DELETE the "Product categories" (SEE Chapter 3 of 2002 edition);

— ADD the "Product marks" (SEE Chapter 4 of this edition);

— ADD the "General requirements" (SEE Chapter 5 of this edition);

— ADD the technical requirements and experimental methods for the

permanence of antibacterial (SEE Section 7.3 of Chapter 6 of this edition);

— MODIFY the definitions of "antibacterial" and "antibacterial ceramic" (SEE

Sections 3.1 and 3.3 of this edition);

— ADD the "Antibacterial test conditions" (SEE Section 7.1 of this edition);

— MODIFY the detailed provisions on the methods of antibacterial

performance test (SEE Appendix A of this edition; Appendix A of 2002

edition).

Appendix A of this Standard modifies-adopts ISO 22196.2011 Measurement of

antibacterial activity on plastics and other non-porous surfaces.

According to the conditions of microbiological experiments in our country, this

Standard makes some modifications when adopting ISO 22196.2011.The

relevant technical differences have already been compiled into the Appendix A.

The existing major differences are as follows.

— This Standard deletes the "8.3 Calculation of the antibacterial activity" of

ISO 22196.2011, and changes it into "A.4.2 Calculation of the

antibacterial rate", which is to consider using the common methods for

representing the antiseptic function of our country's existing products;

— This Standard deletes the Appendixes A and B of ISO 22196.2011;

— This Standard makes some editorial changes to ISO 22196.2011

according to the requirements of national standards.

This Standard was proposed by China Building Materials Association.

This Standard shall be under the jurisdiction of the Technical Committee for

Standardization of Environment-friendly and Healthy Building Materials in the

Building Materials Industry.

Antiseptic function of antibacterial ceramic

1 Scope

This Standard specifies the terms and definitions, product marks, general

requirements, technical requirements, test methods, and inspection rules of

antibacterial ceramic.

2 Normative references

The following documents are essential to the application of this document. For

dated references, only the versions with the dates indicated are applicable to

this document. For undated references, only the latest versions (including all

the amendments) are applicable to this document.

GB 4789.2 National food safety standards – Food microbiological

examination. Aerobic plate count

3 Terms and definitions

The following terms and definitions apply to this document.

It refers to the generic terms of inhibiting and killing the growth and proliferation

of bacteria, saccharomycetes, moulds, and other microorganisms.

It refers to the ceramic with antiseptic function on the surface.

4 Product marks

MARK the antibacterial ceramic according to the sequence of product name,

standard number, symbols of the antiseptic function, antibacterial rate of the

antiseptic function, and antibacterial rate of the permanence of antibacterial.

5 General requirements

The basic performance of the antibacterial ceramic shall conform to the

provisions on the corresponding category of products specified in the national

or industry standards.

6 Technical requirements

The antiseptic function and permanence of antibacterial of antibacterial ceramic

shall conform to the provisions specified in Table 1.

7 Test methods

SIMULATE the cleaning ways of the products during use. USE sodium

hypochlorite disinfectant to repeatedly scrub the surfaces of test samples.

DETECT the antiseptic function of the surfaces of test samples after scrubbing.

8 Inspection rules

CONDUCT group-batching according to the group-batching methods specified

in the relevant product standards.

USE one-time sampling scheme for the detection of antiseptic function and

permanence of antibacterial. TAKE six samples at random from a batch of

products submitted for inspection as test specimens.

Appendix A

(Informative)

Antiseptic function test method

USE the film adhering method to let the bacteria uniformly contact with the test

specimens via the quantitative inoculation of bacteria on the test specimens to

be detected. After a certain time, DETECT the viable count on the test
