3 CLASSIFICATION AND SIZES

3.1 SVEZA COLOR plywood with the EXT/FSF mark is manufactured ac-

cording to the degree of glue joint water resistance: plywood with enhanced water re-

sistance of the glue joint, glued using phenol-formaldehyde adhesives, and intended

for indoor and outdoor usage. 3.2 Depending on the orientation of the grain of adjacent layers, SVEZA COLOR plywood is separated into: - Х – with perpendicular grain direction; - U – with parallel grain direction; - G – with combined grain direction.

3.3 Depending on applied coating type and method, SVEZA COLOR plywood is divided by surface types:

- F – smooth surface; - W – surface with net-line coating; - SP – surface for further painting;

- UN – surface without coating. Note: 1. Surface types may be combined. 2. In formulating orders and marking plywood stacks for a surface without coating, the des-

ignation of the plywood surface layer grade is indicated according to STO 00255177-001.

3.4 Depending on the surface appearance, the SVEZA COLOR plywood is di-vided into grades: 1sel, 1, 2, 3.

shall be performed as per GOST 9620, GOST 27678, GOST 30255, GOST 32155,

[1], [5].

6.2 Plywood length and width are measured at two points parallel to the edges,

at least 100 mm from edges with a metal tape according to GOST 7502 with a toler-

ance of 1 mm. The arithmetic mean value of the two measurements is considered the

actual length (width) of the sheet.

6.3 Plywood thickness shall be measured with thickness gauge GOST 11358 or

micrometer as per GOST 6507 with scale unit up to 0.1 mm at a distance not less

than 25 mm from the edges, in the middle of each sheet's face.

The arithmetic mean value of the four measurements is considered the actual

thickness of the sheet.

Thickness difference in one plywood sheet is defined as the difference between

the maximum and the minimum thickness of the four measurements.

6.4 Out-of-squareness of a sheet of plywood

6.4.1 Out-of-squareness in a plywood sheet is measured with a measurement

square according to GOST 3749. Out-of-squareness is defined by the maximum devi-

ation of the sheet's edges from the surface using a square and metal ruler according to

GOST 427 with a tolerance of 1 mm.

6.4.2 Out-of-squareness may be also determined by the difference of diagonal

lines of the sheet measured by metal tape ruler as per GOST 7502 with the scale unit

value 1 mm.

6.5 Out-of-straightness of a plywood sheet's edges shall be determined by

measuring the maximum gap between the sheet's edge and the edge of the metal ruler

using a probe according to GOST 8925 with a tolerance of 0.2 mm.

up to 80%.

8 MANUFACTURER’S WARRANTY

The manufacturer shall guarantee conformance of SVEZA COLOR plywood to

the quality requirements of the existing standard if transportation and storage condi-

tions are satisfied.

The EXT / FSF grade plywood guaranteed shelf life is 5 years following the

day of receipt by customer.

If the plywood is to be used for further processing, it is recommended to con-

tact the manufacturer for more details about the properties and specifications of the

plywood.

9 SAFETY AND ENVIRONMENTAL REQUIREMENTS

9.1 The content of hazardous chemicals emitted into residential or public build-

ing air during use of plywood products must not exceed the requirements under items

[6], [7], [8].

9.2 Plywood must be produced using materials and components approved by

the national sanitary and epidemiological inspection authorities.

9.3 Only persons age 18 and older with a clean bill of health are allowed to

work in plywood production. Medical examinations are conducted according to the

applicable instructions from the Ministry of Health of the Russian Federation.

9.4 Personnel engaged in plywood manufacturing must be provided with per-

sonal protection equipment according to the applicable regulations under GOST

12.4.011.

9.5 The specific activity of Cesium 137 in plywood must not exceed the health-

based exposure limits set forth in [9].

STO 00255102-004-2017

14

9.6 The standard plywood composition does not include raw materials or com-

ponents classified as hazardous waste.

9.7 Plywood usually has a long service life, and there are a number of ways to

recycle it. Plywood must be recycled taking into account the ordinances regarding re-

cycling in the effective laws of various countries.

10 RECOMMENDATIONS FOR USE

10.1 SVEZA COLOR plywood is designed for multiple application. Adherence

with plywood application and storage regulations will make it possible to increase its

service life.

10.2 Transportation of SVEZA COLOR plywood must be carried out in an en-

closed truck, protected from adverse weather conditions. In transportation, it is essen-

tial to avoid humidification to avoid swelling at the edges, sheet warping, and mas-

sive indentation of packing straps or other quality loss.

10.3 Slight variation in the SVEZA COLOR plywood thickness due to moist

air during transport, along the edge for a distance up to 50 mm from the edge is al-

lowable.

10.4 SVEZA COLOR plywood intended for vehicles must be stored properly:

storage in closed premises that protect plywood from atmospheric precipitation.

10.5 Sawing SVEZA COLOR plywood for parts must be performed with band

or circular saws designed for cutting plywood. To obtain a clean cut, the sawingmust

be performed correctly. First, the sawing is to be done transversely to the face side of

the grain direction, and then lengthwise. This method makes it possible to avoid split-

ting the corners and to decrease face chip size and quantity. While sawing with a cir-

cular saw, high speed and low feed rate are recommended.

To prevent plywood from moisture absorption, in case of cutting, the SVEZA

COLOR plywood butt ends must necessarily be treated with special types of water-

based emulsion paint or another sealant.

10.6 All the holes made during installation works, in order to prevent moisture

penetration into the SVEZA COLOR plywood must be filled with water-based emul-

sion paint or other sealants, and it is recommended to treat the sheet surface with wa-

ter-repellent compound.

When drilling, holes with even edges are obtained with the use of a drill sharp

enough and equipped with a front cutter. Drilling should start from the face side. Use

of a padding sheet makes it possible to avoid splitting on the board reverse face.

When using nails, to avoid splitting the plywood layers, nails with thread or

special wood screw are suitable. A distance from the sheet edge to nail of (12-15)

mm is considered as appropriate.

10.7 Rippling is common, wave-shaped convexities on the surface of film-

faced plywood, related to the technology of wood processing and wood material

STO 00255102-004-2017

15

properties, and approximately up 0.8 mm height and various length. These are due to

water absorption by the plywood.

This is especially often observed when plywood is used under conditions of

plywood and water direct contact.

For use in open premises, sudden climate change during the day and/or season-

al precipitation conditions (for example, spring and autumn months) may also con-

tribute to the appearance of the ripple effect.

The waviness formation continues until complete saturation with moisture up

to approximately 28% through cut edges, edges without additional sealant protection,

drilled holes, installed rivets or phenolic film damages not seen during visual exami-

nation with the unaided eye.

After complete saturation, the waviness from sheets surface disappears almost

completely, normally after 2-3 cycles of plywood contact with water and drying after

each contact.

ANNEX E

(mandatory)

Method of determination of resistance to vapor

In a 500 ml flask with a neck diameter of 60 mm, water is poured to half and

boiled.

The plywood sample is placed firmly on the flask neck and exposed to vapor

for 60 minutes.

After exposure, the sample is removed and dried, and the degree of damage is

visually checked according to a three-point scale:

1 - No swelling. Minor gloss loss. No blisters.

2 - Minor swelling across the whole surface. Gloss alteration. Minor blisters

formation.

3 - Intense swelling. Intense gloss alteration. Intense blister formation.

APPENDIX F

(mandatory)

Method of determination of resistance to sodium hydroxide (NaOH)

A 5% NaOH solution is poured into a glass dish with a capacity of approxi-

mately 50 ml. The plywood sample is pressed firmly from the top so as to leave ap-

proximately 10 cm distance from the cup to the sample edges. Then the plywood

sample is turned over 180 ° with the cup so as to have the solution moistening the

plywood surface, and left for 2 hours.

Plywood resistance to sodium hydroxide is assessed by solution color change:

1 - Clear – total curing of film.

2 - Light-yellow color - normal film curing.

3 - Saturated yellow color - films undercured.

STO 00255102-004-2017

APPENDIX G

(mandatory)

Method of determination of surface waviness of SVEZA COLOR plywood

used for formwork (Rippling test)

The test is carried out on samples of film-faced plywood of size (100x100xS)

mm, with punctures on the surface of the face layers.

On the sample surface, 9 punctures are made with a 1 mm diameter drill to a

depth of the film thickness + the “jacket”.

Before the tests are conducted, the butt surfaces of the samples are painted

along the edges with water-based acrylic paint.

Tests must be performed on both faces of the sample (upper and lower).

Samples with punctures are to be covered with a damp cloth and left for 2

hours, periodically moistening the cloth.

The tested surface is subjected to visual inspection and waviness measurements

with a measurement ruler.

Length measurements of all beams with ruler, rays lengths should be summed

and divided by 9 (number of punctures).
