JC/T 564.1-2018Fiber reinforced calcium silicate boards - Part 1: Non-asbestos calcium silicate boards (English PDF)

Foreword

This part was drafted in accordance with the rules given in GB/T 1.1-2009.

JC/T 564 "Fiber-reinforced calcium silicate board" is divided into two parts:

- Part 1: Non-asbestos calcium silicate boards;

- Part 2: Asbestos calcium silicate board.

This part is the part 1 of JC/T 564. This part was revised with reference to ISO

8336:2009 "Fiber-cement flat sheets - Product specification and test methods",

ISO 1896:1991 "Products in fiber-reinforced cement - Non-combustible fiber-

reinforced boards of calcium silicate or cement for insulation and fire protection",

ISO 390:1993 "Products in fiber-reinforced cement - Sampling and inspection".

This part replaces JC/T 564.1-2008. As compared with JC/T 564.1-2008, in

addition to editorial changes, the main technical changes are as follows:

- MODIFY the "Scope". DEFINE that this part is applicable to the non-

asbestos calcium silicate boards which have fireproof, thermal insulation,

dampproof requirements as used for building interior wall panels, exterior

wall panels, suspended ceiling panels, carriages, offshore structures, ship

interior partitions, composite insulation panels; it may also be applicable to

the non-asbestos calcium silicate boards which are suitable for other

purposes such as home decoration (see clause 1; clause 1 of the 2006

version);

- MODIFY the expressions in the normative references (see clause 2; clause

2 of the 2008 version);

- In the normative reference, MODIFY the year number of GB/T 5464, GB/T

7109, GB 8624, GB/T 10294; ADD 6 standards: GB/T 12954.1-2008, GB/T

23263-2009, GB/T 24321, JC/T 409, JC/T 414, JC/T 622 (see clause 2;

clause 2 of the 2008 version);

- MODIFY the definition of fiber-reinforced calcium silicate boards (see

clause 3; clause 3 of the 2008 version);

- ADD the definition of the textured sheets and saturated shear board

performance (see clause 3);

- ADJUST the specification size. INCREASE the length to 4880 mm (see

Table 2; Table 1 of the 2008 version);

- The non-asbestos calcium silicate board is divided into three categories

according to the use, that is, category A, B, C. MAKE corresponding

adjustments for the markings of the flexural strength grade and the impact

strength grade (see clause 4; clause 4 of the 2008 version);

- MODIFY the standard basis for the raw materials (see clause 5; clause 5

of the 2008 version);

- In the appearance quality, MODIFY the back quality requirements (see

Table 3; Table 2 of the 2008 version);

- Separately LIST the shape deviations. For the thickness non-uniformity in

the shape deviation, PROPOSE different indicators based on thickness.

Appropriately IMPROVE such indicators as edge straightness, diagonal

difference, flatness (see Table 4; Table 3 of the 2008 version);

- MODIFY the index requirements for dimensional deviation. PROPOSE

different indicators for the length and width based on different intervals. The

thickness is divided into textured sheets and non-textured sheets.

PROPOSE different indicators based on different thickness intervals (see

Table 5; Table 3 of 2008 version);

- ADD the requirements for asbestos composition;

- MODIFY the requirements for the items and indicators of physical

properties. CANCEL the indicators of moisture content and heat shrinkage

rate. The apparent density is explained by the supplier in the quality

document. ADD the requirements for such indicators as moisture

absorption rate, hot rain performance, hot water performance, immersion-

drying performance, flexural strength in frost-resistance test (see Table 6;

Table 4 of the 2008 version);

- MODIFY the code of flexural strength grade to R1, R2, R3, R4, R5. MODIFY

the flexural strength indicator. CHANGE the vertical and horizontal strength

ratio items in the original standard into the lowest strength of single block;

for the category A and B sheets, CHANGE it into the requirements for

strength indicator in saturated state. ADD the requirements for three

mechanical properties: impact strength, impact resistance, saturated shear

board performance (see Tables 7 and 8; Table 5 of the 2008 version);

- MODIFY the representation of the test method. USE form to list the test

method corresponding to each item. SUPPLEMENT the test method of the

test items as added in this part (see Table 9; clause 7 of the 2008 version);

- ADJUST the exit-factory inspection items. CANCEL the moisture content.

ADD the item of water absorption rate (see 8.2.1; 8.2.1 of the 2008 version);

- MODIFY the type inspection conditions (see 8.3.1; 8.1.2 of the 2008

version);

Fiber reinforced calcium silicate boards -

Part 1: Non-asbestos calcium silicate boards

1 Scope

This part specifies the terms and definitions, classification, grades,

specifications and markings, raw materials, requirements, test methods,

inspection rules, signs, certificates, transportation, packaging, storage of non-

asbestos calcium silicate boards (shortly referred to as non-asbestos calcium

silicate boards).

This part is applicable to the non-asbestos calcium silicate boards which have

fireproof, thermal insulation, dampproof requirements as used for building

interior wall panels, exterior wall panels, suspended ceiling panels, carriages,

offshore structures, ship interior partitions, composite insulation panels; it may

also be applicable to the non-asbestos calcium silicate boards which are

suitable for other purposes such as home decoration

8 Inspection rules

2014 to prepare the specimen.

4 in Table 11), it shall make the second sampling, to take the sample of the

equal quantity as the first sampling to carry out test:

a) The specimens as taken in the second time shall be inspected according

to the methods as specified in clause 7 of this part;

b) The number of unqualified samples at the first inspection is added to the

number of unqualified samples at the second inspection to obtain the total

number of unqualified samples;

c) When the total number of unqualified samples is equal to the total

accepted quantity Ac2 as specified in column 5 of Table 11, the item of this

inspection batch is judged to be qualified;

d) When the total number of unqualified samples is equal to or more than the

second rejected quantity Re2 as specified in column 6 of Table 11, it is

determined that the inspection batch is unqualified.

9 of Table 11, if the average value of sample is >= AL and the

minimum strength of the single block is qualified, the flexural strength item

is judged to be qualified; if the average value of sample is or the

minimum strength of the single block is unqualified, the flexural strength

item is judged to be unqualified;

b) Impact resistance, saturated shear board performance: When all the

samples inspected are qualified, the item is judged to be qualified; when

there is unqualified sample, this item is judged to be unqualified.
